[Felix Galindo]

Is the mDot with programming header compatible with this usb adapter board?

Or is there another usb adapter board you recommend>

Felix,

For issuing AT commands to the mDot, this board will probably suffice. You will not, however, be able to flash new programs on your mDot or see debug output when using this board.

Our MDK (Micro Developer Kit) board, on the other hand, allows you to flash your mDot with new programs, see debug output as well as use the AT command port, and has been fully tested with the mDot. Here’s a link:

Hope this helps!

Cheers,

Mike

Is there a guide on how to send AT commands to the MDK? When I connect it to my Mac – two ports show up. For example – they showed up as usbmodem14121 and usbmodem14113. I can see the console output on the port 14113. I tried sending AT commands on 14121 but I don’t see any output.

Ashu,

Usually the first port that enumerates (lower number) is the debug port and the second port is the AT command port.

Also, make sure your baud rates are correct. The mDot AT firmware uses 115200 as the default for both the debug and AT command ports. You should also disable any hardware or software flow control in your terminal application.

Cheers,

Mike
