When I have the HC-06 powered from the board (either 3.3V or 5V) & try to upload to the board I get,
Target no device found
Error in initializing ST-LINK device.
Reason: No device found on target.
Yet when I unhook the module from the board everything uploads fine.
So, I uploaded to check my debug serial connection without the HC-06 connected, all fine.
Hook up the module, no debug . Its as if connecting it up to the power on the board knocks out the USB-ST-Link.
When I plug into the 5V - debug drops, LED3 goes out & LED1 starts flashing.
When I plug into to 3.3V - debug stops but the LEDs remain on.
I've swapped out the HC-06 module but I still get the same behaviour,
All power is being supplied by the US-ST-Link
