MqttSocket_Write "client->write.pos" not reset when socket write fail

[trzhongty]

mqtt_socket.c MqttSocket_Write

In blocking mode, "client->write.pos" is not reset when the "MqttSocket_WriteDo" result is less than 0. which in turn causes the wrong offset data to be sent when trying to reconnect, further errors until "client->write.pos >= buf_len"

Or should I have to clear client all on reconnect？

Hi @trzhongty

Yes, you are correct, the client structure should be re-initialized prior to attempting a reconnect due to an error or broker disconnect.
