I am trying to run EdgeImpulse locally on a Nano 33 BLE Sense. After flashing the device, it will accept one AT command, but then for every subsequent command, the board returns “Not a valid AT command”. Is this an issue with the serial protocol? I am using coolTerm with baud rate 115200 and 8-N-1.
I tried using screen but get the same issue as well the CR command not being executed.
