Bluegiga BLE112-A: able to program, but unable run see

bluetooth low energyin-circuit

I tried to get Support from Bluegiga directly, but I didn't get an answer (despite the fact that their Zendesk is nearly unusable):

I'm using a BLE112-A on our board:

I've been able to flash my BGScript with the CC Debugger onto the chip, but I can't see it appear in a Bluetooth monitoring app. Flashing the same script onto the development board will show up the chip immediately.

Here's the flash tool's info output from the chip:

I've checked the docs already, but I cannot see the cause. I've tried it with two of my boards. Any ideas?

That schematic is fine. I've powered the BLE112-A with similar setups without issue and the fact you can program it is also a good indication that this is more likely a hardware-software interaction issue. I've had the chips software stall waiting for something to be written out over a hardware interface.

I would do the following:

  • Remove USB support from your hardware config, as those i/o lines are not used
  • Configure UART to match how it is connected (not possible to see from schematic), i.e. if you haven't connected RTS/CTS make sure you aren't enabling hardware config in you system.
  • Remove any writes to hardware you aren't using.

As there's no real debugger for BGScript, one of the best ways to test what happens is to use a simple LED on a GPIO (configured as output) and turning it on in different spots to see what code executes and what doesn't.
