LAUNCHXL-CC2650: Unable to run simple broadcaster demo on Launch Pad board

Kevin Kieffer

Part Number: LAUNCHXL-CC2650
Other Parts Discussed in Thread: CC2650

After building and flashing the simple_broadcaster cc2650lp_stack project and then building and flashing the simple_broadcaster_cc2650lp_app, I can start stepping through the code with the debugger.

I have not modified the demo code at all.

At line 338, where the GAP role parameters are being set in the SimpleBLEBroadcaster_init function of simple_broadcaster.c, the debugger never returns after attempting to execute that line.

Pausing the debugger shows it to be here:

What am I missing? Shouldn't this demo code run "out of the box" on this board?

Hi Kevin,

The demo code should work out of the box. Are you just letting the device run, or are you stepping through it line by line? If you just let it run, do you see it advertising and outputting to the terminal?

Best,

Nate

I don't see it advertising at all. However I can confirm that the simple_peripheral project runs "out of the box".

What SDK are you using for both projects?

Have you built the stack library beforehand? Once I did that on a CC2650 Launchpad I am able to see it advertising.

I think there must be a bug in simple_broadcaster. I was also unable to run it on the BOOSTXL (see this thread: BOOSTXL-CC2650MA: Unable to run simple_broadcaster example, - Bluetooth forum - Bluetooth®︎ - TI E2E support forums)

However the simple_peripheral runs on BOTH boards (as long as the correct board.c is included). So for now I can work off simple_peripheral.

Hi Kevin,

What tool are you using to detect the broadcaster? I think it's unlikely there's a bug because I was able to see it advertising on my end. I would recommend using BTool as your central device to minimize variation across our trials.

Additionally, can you connect your launchpad to SmartRF Studio? If so, can you transmit/receive an unmodulated carrier wave if you have 2 launchpads? This will help us ensure that your launchpad hardware is working as we expect it to.

Best,

Nate
