Running basic tutorial on custom breakout board

[Justin]

Hello,

What changes need to be made to the following tutorial to enable basic advertising with the Rigado BMD-300 on a custom board breakout board?

I've ripped out everything to do with the LEDs and buttons, but I'm still not seeing any advertising data with my custom board.

CONTEXT:

• Verified the code works on the Rigado BMD-300 Series Evaluation Kit.
• Verified a basic main.c can run on my custom board with a BMD-300.
• I'm initializing the clocks with this: APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
• I have also gone through the following blog post: rigado.zendesk.com/.../225674668-Example-files-will-not-run-on-my-hardware-but-do-on-the-Eval-board-

Well that kind of points to a hardware problem. The only difference between the 300 and 301 is an external vs. internal antenna.

The options I see are:

1. Something isn't soldered down correctly module to your board.
2. The BMD-300 module is bad
3. The BMD-300 module might have a pre-production nRF53832 which have some unique software needs.
4. Something is messed up with your RTC circuit on your breakout board.

I would start first by changing the init statement for the SD to run off the internal RC RTC. That should answer number 4.
