Cannot reset SIM7000G module #130

Hi.

when I run the reset program, I get the following output. The baud rate is set correctly. I can't send AT commands to the board from the console. Only when I insert the AT command in the program code will they run. My guess is that I won't get any feedback on the if (SerialAT.available) query if the modem is already running.:

In this way, it is not possible for me to reset the modem. What can I do here?

14:25:32.941 ->

But if I press the reset button on the board again and the modem is already active, I get the following output:

14:32:47.517 -> 
14:32:47.555 -> Testing Modem Response...

Hello I have the same problem with my board. Did you solve it ?

pixelfriese commented 3 years ago

Hi,

Yes, I was able to solve it. The AT commands from the reset script had to be executed manually. After that the module could be used normally again.

In my case I had to change SerialAT.begin(9600, SERIAL_8N1, PIN_RX, PIN_TX); into SerialAT.begin(19200, SERIAL_8N1, PIN_RX, PIN_TX); and only then it worked. Hope this helps.
