API cleanup and bugfixes to get minimal functionality #13

puddly · 2024-04-10T22:09:48Z

This is a fairly large PR but until the radio library is actually functional I don't see a need to split it up.

I've made a few changes:

Adjusted the command serialization/parsing to work with the device's actual serial protocol instead of modifying the deCONZ protocol.
Renamed commands to more closely match what is in the SDK.
Renamed all getter API functions to use a get_ prefix and setters to use set_.

At the moment, a few things do not work:

Radio startup does not work properly without adding fake endpoint objects because endpoint registration doesn't appear to be functional. The endpoints are registered but the coordinator does not respond to the loopback Active_EP_req with anything other than [242, 242] (also a bug?).
Restoring a backup crashes if set_nwk_extended_panid is called. If this call is removed, backup restoration "works" but no new settings are actually written.
permit similarly doesn't work and crashes with the same error as above.
There are no firmware commands to report the current firmware version, board name/model, or manufacturer name.
There is no way to reset the firmware into a known state. I'm intentionally crashing it to do so, but this isn't a very good way.

I believe that many of these issues stem from the network startup/shutdown/settings writing sequence being unclear. I wasn't able to find anything in the documentation about forming a new network with specific settings, especially with the radio already running.

For the library to be functional with ZHA, the following need to work and they are what I am currently trying to fix:

# Leave the current network and erase all settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB reset

# Form a temporary network, perform an energy scan to find a good channel, then use the settings provided by zigpy
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB form

# Dump the current network settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB backup -z > backup.json

# Form a new network with random settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB form

# Restore the old network settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB restore backup.json

# Dump the settings again
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB backup -z > backup2.json

# They should be identical except for the frame counter increasing by 5000 and the backup timestamp changing
diff backup.json backup2.json

# Energy scanning should work
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB energy-scan

# And finally, new devices can join the network and be interviewed by zigpy
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB permit

Could you explain a little more the process to read/write network settings like I have above? The write_network_info function should be pretty simple at this point so let me know what should be changed to get it working. I've added # TODO comments throughout the library in places where I ran into trouble.

Let me know if you have any questions!

CC @Maxwelltoo, as you mentioned having interest in helping out.

Maxwelltoo · 2024-04-11T03:19:57Z

Understood, I’ll take a look at these issues.
I'm completely new to Zigbee, and I'm more comfortable with C than Python. So, it will take me some time to go through the documentation and source code. Once I make some progress, I'll be sure to let you know.

@puddly Please see the explain as follows:

# TODO: implement a proper software-driven watchdog

A: OK, Let's do it

# TODO: Most commands fail if the network is not formed. Why?

A: The form_network command will initialization Zigbee stack and select the device role, so some commands must run after it.

# TODO: add our registered endpoints manually so things don't crash. These should be discovered automatically.

A: OK, Let's do it

# TODO: Why does setting the extended PAN ID trigger a crash?

A: From the LOG, it seems doesn't include the extended PAN ID in the send Frame.

Fixed, thanks.

# TODO: Network settings do not persist. How do you write them?

I've tried adding await self._api.start(autostart=True) in various places at the end of form_network but I still cannot get the new network settings to take effect.

We expect that write_network_info configures all of the network settings of a device. This is how the code currently looks:

Reset (via crash, sorry!) to get into a known state
network_init()
form_network(role=DeviceType.COORDINATOR) (without this, I can't send other commands)
start(autostart=False) (without this, I can't send other commands)
Write all of the new settings.
start(autostart=True)
- I immediately get Received indication CommandId.form_network{'extended_panid': 74:4d:bd:ff:fe:60:3c:ae, 'panid': 0x6EAA, 'channel': 22}, which is not correct. It seems at this point the settings are not written.

After a reset, the old settings are still there. I think there is some issue with the order in which these commands are called. I've tried removing some and changing autostart but it doesn't seem to matter, the settings don't persist.

I sniff the packet, It seems that 242 endpoint which be green power proxy must include from ZigBee PRO 3.0 as Coordinator/Router device. Could you also check again?

We expect that the add_endpoint command registers an endpoint on the device that can then be queried by sending a loopback (0x0000 -> 0x0000) ZDO Active_EP_req. These are the default endpoints](https://github.com/zigpy/zigpy/blob/18a7add71a546ba009e811c153a61c60d7f0987a/zigpy/application.py#L714-L750) zigpy registers so my expectation is that the loopback Active_EP_req would respond with [1, 2] or [1, 2, 242], not [242, 242]. Having the same endpoint twice seems like a bug.

Alternatively, is there a specific time when add_endpoint can be called? Before start(autostart=True), network_init(), or form_network(role=DeviceType.COORDINATOR)?

puddly · 2024-04-16T17:49:46Z

I've cleaned up the command serialization and deserialization. All commands are now in a commands.py module and should have clear structures. This doesn't change the way the code works but it should be much simpler to understand.

lhespress · 2024-04-17T03:22:02Z

@puddly

Reset (via crash, sorry!) to get into a known state

network_init()

form_network(role=DeviceType.COORDINATOR) (without this, I can't send other commands)

start(autostart=False) (without this, I can't send other commands)

Write all of the new settings.

start(autostart=True)

Start command mean start ZigBee stack, once call, it'll start top level commissioning and indication information when formed network successfully, like this:

Received indication CommandId.form_network{'extended_panid': 74:4d:bd:ff:fe:60:3c:ae, 'panid': 0x6EAA, 'channel': 22},

It'll only return command response but don't do anything if repeat call start command when has called start command. the follow steps is suggestion:

Resetto get into a known state
network_init()
form_network(role=DeviceType.COORDINATOR)
Write all of the new settings.
start(autostart=True) or start(autostart=False)

True: It initializes, load some parameters from NVRAM and proceed with startup.
False: It initializes scheduler and buffers pool, but not MAC and upper layers.

Alternatively, is there a specific time when add_endpoint can be called? Before start(autostart=True), network_init(), or form_network(role=DeviceType.COORDINATOR)?

The add_endpoint must be be called after form_network(role=DeviceType.COORDINATOR), there isn't a specific time for start(autostart=True).

puddly · 2024-04-17T03:56:37Z

Thank you. I've tried the modified startup sequence but there doesn't appear to be a change, settings still aren't persisting.

There is no reset command but we can trigger a crash if we form the network twice

What means about the reset command? restart or factory the device?

@KlimovVladimir Yes，It'll be update once the firmware as the attachment has been checked and match the function.

puddly · 2024-06-04T18:08:57Z

@lhespress Sorry for the delay. I've tested the firmware and made some adjustments to this branch. It looks like things are getting better.

Things that now work:

Model string, manufacturer string, firmware version, reset, and factory reset commands
Network backup and restore!

Things that do not:

Factory reset initially works but a new network is formed if you take a backup immediately after. When the stick is factory reset, it should not have any network settings.

I think I am confused about the stack startup sequence. Could you explain how to do the following?

Connect to the stack, reboot, and then load the network settings without starting or forming a network.
Connect to the stack, reset, and then check if there is a formed network without forming a new one.

Other than that, it would be nice if the stack sent some sort of indication upon boot or reset, as this would allow the reset() command to work better (without polling) and also would allow the application to immediately detect when the stack has crashed and reset.

@Hedda There is some changes for startup sequence for the issues @puddly mentioned, i'll update it this week.

lhespress · 2024-07-17T07:10:47Z

@puddly

Factory reset initially works but a new network is formed if you take a backup immediately after. When the stick is factory reset, it should not have any network settings.

That's because of it'll form a network automatic after start command, i changed the startup sequence which can read and write the network information without form command. BTW, it must call factory command when write network information with forming a network.

Connect to the stack, reboot, and then load the network settings without starting or forming a network.

reboot means restart the device, right?

It can't load network setting without forming a network in the build0516.zip firmware. I have changed in the follow firmware.

Connect to the stack, reset, and then check if there is a formed network without forming a new one.

reset means factory reset the device, right?

That's because of it'll form a network automatic after start command, so it'll forming a new network in the build0516.zip firmware.

It'll sent an factory indication without forming a new one in the follow firmware.

Other than that, it would be nice if the stack sent some sort of indication upon boot or reset, as this would allow the reset() command to work better (without polling) and also would allow the application to immediately detect when the stack has crashed and reset.

It'll sent an indication when factory or reset in the follow firmware.

Please download the firmware build0717.zip which change startup sequence and match with fixes-serialization branch.

Hey everyone, I'm interested in using an ESP32-C6 as a zigbee coordinator radio as part of the zigpy stack. I see this PR is linked in various upstream issues as a blocker and wanted to see if there's some way I can help with testing or bug fixes.

Any specific areas you think are good to jump in and help?

@robbawebba Thanks for your help firstly. Could you help confirm the function use the firmware build_1016.zip on ESP32-C6 which UART use GPIO4 (RX) and GPIO5 (TX)?

puddly · 2024-10-16T16:25:34Z

@lhespress I have a request. Would it be possible for you to build a version of the ESP32-H2 firmware that uses the USB-C UART port of the device? Testing it with a USB-UART adapter requires extra wires and USB ports compared to other coordinators that can function just over USB.

Unfortunately, the new firmware doesn't appear to work very well. Reset indications are not sent on startup and network formation no longer respects the written settings.

Just to make sure we're on the same page, here is exactly how I am testing:

# In the zigpy-espzb virtualenv
pip install git+https://github.com/lhespress/zigpy-cli@feature/zigpy_espzb
pip install -e .  # To install the development version of zigpy-espzb

# Leave the current network and erase all settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB reset

# If you try to read settings, you should get a `NetworkNotFormed` error
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB backup -z

# Form a temporary network, perform an energy scan to find a good channel, then use the settings provided by zigpy
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB form

# Dump the current network settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB backup -z > backup.json

### At this point, read `backup.json` and make sure the settings match what zigpy wrote

# Form a new network with random settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB form

# Restore the old network settings
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB restore backup.json

# Dump the settings again
zigpy -vvv radio --baudrate 115200 znsp /dev/cu.usbserial-A94TYUSB backup -z > backup2.json

# They should be identical except for the frame counter increasing by 5000 and the backup timestamp changing
diff backup.json backup2.json

You will see in the log output what settings the form command is trying to write. Can you explain what exact commands I need to run, from the moment I connect to the serial port, to:

Check if a network exists.
Form a network with the exact, provided settings.
Start the current network, if one exists.
Load the currently-written network settings without starting the network.

I feel there is some mistake with the connect() code or the write_network_info() code.

@puddly Please check build_1022.zip which use the USB-C UART port of the device for command. BTW, if you want to show the log which use GPIO4 (RX) and GPIO5 (TX) as UART.

Hi @lhespress, I was able to test the same functionality outlined above on ESP32-C6. I observed a few results that don't match the expected outcome, but I'll let you be the judge of that since I'm new to this effort.

Below are the test steps and observations. Attached are the zigby cli debug logs.
2024-10-22-build_1016.testlog.txt

Leave the current network and erase all settings
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 reset
✔️ Looks like the device rebooted and reset
If you try to read settings, you should get a NetworkNotFormed error
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 backup -z
❌ Zigpy dumps some network settings, no NetworkNotFormed error observed
Form a temporary network, perform an energy scan to find a good channel, then use the settings provided by zigpy
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 form
✔️ A network appears to be formed
Dump the current network settings
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 backup -z > backup.json
⚠️ Settings dumped to JSON, with a warning: "Backup is incomplete, ignoring"
At this point, read backup.json and make sure the settings match what zigpy wrote
✔️ settings.json appears to be complete, I'm not sure what's missing or incomplete
Form a new network with random settings
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 form
✔️ A network appears to be formed
Restore the old network settings
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 restore backup.json
⚠️ This command seemed to fail due to an exception "backup is incomplete". but the next step may indicate that the restore succeeded?
Dump the settings again
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 backup -z > backup2.json
✔️ Only difference between the backups is the "backup_time" field.
They should be identical except for the frame counter increasing by 5000 and the backup timestamp changing
diff backup.json backup2.json
⚠️ Only difference between the backups is the "backup_time" field. Frame counter is not increased. Both show a frame counter of 5000.
Energy scanning should work
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 energy-scan
❌ Warning observed: WARNING Coordinator does not support energy scanning
❌ After mean 5 / 5 finished, the energy scan attempts seem to repeat forever. SIGINT is required to end the command.
And finally, new devices can join the network and be interviewed by zigpy
$ zigpy -vvv radio --baudrate 115200 znsp /dev/ttyUSB1 permit
✔️ I see devices joining the network.

Please let me know if you need additional testing help or more logs! Maybe I'll try setting this up with ZHA too.

@lhespress You can see from @robbawebba running the tests that there are still some problems.

Can you explain what exact commands I need to run, from the moment I connect to the serial port, to:

Check if a network exists.
Form a network with the exact, provided settings.
Start the current network, if one exists.
Load the currently-written network settings without starting the network.

I feel there is some mistake with the connect() code or the write_network_info() code. From the tests, it's clear that the coordinator is not starting up properly and network settings are not persisting.

lhespress · 2024-11-01T08:41:01Z

@puddly

Check if a network exists.

What do you mean how to check whether have formed a network or not?

Form a network with the exact, provided settings.

You can setting any information before call the form command.

Start the current network, if one exists.

It'll start the network if has formed when call start command.

Load the currently-written network settings without starting the network.

The newest firmware has supported it.

lhespress · 2024-11-01T09:06:47Z

@robbawebba Thanks for you share the test result.

If you try to read settings, you should get a NetworkNotFormed error

Reset command only reboot the device, it doesn't erase all setting, factory command will do it.

They should be identical except for the frame counter increasing by 5000 and the backup timestamp changing

The frame counter use a same value now, i can change it on next update.

Energy scanning should work

Can you explain what the mean of Energy scan? Active scan available network or Energy detect?
