I am using BX3105 module for one of my project. In that, I used AT+KTCPSTART=1 to start direct flow communication with server. After starting this mode I'm not able to use AT commands. So, I need to exit from that mode. But I have tried many way to get out from direct data flow mode after connecting to server, I don't know how to disconnect from server. Only after resetting the module, I can able to use AT commands. Is there any way to disconnect from that direct data flow.
