AT commands to shut down bluetooth module

Thread Starter

I'm trying to save battery life on a device I'm building by shutting down bluetooth when communication is not required. Ideally, I would like to do that from the Arduino microcontroller.

I assume that the safest way to do that would be to use a transistor switch on the Vin of the board but I wonder if there are functions embedded on those module, possibly an AT command that would allow me to do that programatically.

I'm struggling to 1) wrap my head around AT commands 2) find a good reference for HM-10 and HC-05 bluetooth modules AT commands.

Any help is appreciated
