Use AT commands over UART on mDot

Hi, so I’m trying to use the mDot as a LoRA module for another microcontroller through the use of AT commands.

I’ve hooked up my UART pins to pins 2 and 3 of the mDot for communication and try sending “AT” among other failed attempts, and I get no response from the mDot.

I can tell that the mDot is on, as I am measuring a current draw through a multimeter, so I’m lost at what the issue might be.

It is possible to use the mDot like a separate module and send packets over LoRA using just the AT commands sent over the UART pins on the default firmware, right?

I don’t have a development board, so I can’t simply plug the mDot to USB.
