TCP socket not delivery data

[alex0732]

Hi!
There is a bunch of arduino MEGA256 - esp8266. It works fine, correctly sends data to the server via MQTT. It is required to remake on TCP-socket. I do as in the example, in debug I see the following output:
185270> SOCKET #0: send dataLen=135 socketData=#A0:20:A6:02:20:9C

No data is sent to the server. Confusing extra bytes "�n�?(" after "##", they are not in the original packet. "##" - is the end of packet.
The python test script delivers data to the server normally. Tried with firmware esp-link v3.0.14-g963ffbb and v3.2.47-g9c6530d.
El-client - last release. What is my problem? err=-11 - is normally closed session?
