AT Command baud rate

#1

Hi,

I’m trying to use a Arduino nano to send AT commands to cubecell. The problem is the nano uses the same serial pins for hardware + computer comms, meaning I can’t debug properly.

I’m wanting to use Software Serial on the Arduino nano to free up the tx and rx pins on the nano. However software serial is only reliable at lower baud rates (not 115200)

Is it possible to lower the default baud rate of cubecell AT command mode to something lower? Below 50k?

Thanks!

Yes, but some printed data may be garbled.

#3

If AT command mode on heltec can be set to 9600 and software serial set to 9600 on nano, it should not be garbled though?

How to adjust AT command default baud rate?

Thanks

AT_Command change Serial.begin(Baud rate you want), then download the program.
