When trying to use TRB142 in full control mode, connecting on network and opening socket in transparent mode using:
AT+QIOPEN=1,1,"TCP",<"//My Ip//">,5011,5011,2 socket opens, device is connected to server and data is passing through.
However when trying to exit data mode using "+++" and following instruction (not sending anything 1 second before and after, and not using CR, LF characters) as stated in quectel AT comand manual, socket stays open in data mode, and doesnt switch to command mode. AT&D0 is configured. Is there another way to exit data mode in full control modem on TRB142?
