The modem runs at 9600 baudrate. What would be the right command to read the response instead of read() ?

I'm now connected over the WebREPL and I can send the commands, but the response is somehow strange. I would expect something different. >>> uart.write('AT+CFUN=1,1\r'.encode()) 12 uart.read() or uar.readline() shows nothing..

OK, thx!

Ok, now it seems working. But when I put uos.dupterm(None, 1) into the terminal, it stops working, the terminal hangs.

I've flashed the same boot.py, but still the same result. I'm currently running no main.py. FW is
esp8266-20180511-v1.9.4.bin

Thanks for linking the post. I couldn't get it working yet, I posted some additional questions in the linked post.

I'm working on something similar. I have a modem hooked up to my ESP8266 12E via serial in order to send a receive AT commands to the modem. The cabeling is a follow: ESP8266 3.3V --> Modem 3.3V ESP8266 GND --> Modem GND ESP8266 RX --> Modem TX ESP8266 D4 --> Modem RX However, if I run the uos.dupte...

I have a ESP8266 12E I would like to connect to a SIMCOM7000E modem over serial connectivity (RX / TX). Here in the forum I read, that the serial interface is already occupied by the REPL. Is there even a way to connect the modem over serial to the ESP8266? I've already achieved the same with Arduin...
