ble_hrs on a custom board

[sd]

Hello. I'm trying to port the ble_hrs to a custom board with an NRF51822 on it, but the advertising never starts. While I'm debugging this, what should I be looking out for that would make the design not work properly on the chip? I have only one button, and I set the LEDs to different pins.

There isn't a lot to go on here so I'll ask a couple of basic questions:

1. Is the soft device programmed on your chip before attempting to start your application?
2. Is the application throwing an ASSERT of some sort during your initialization?
3. Can you trace the initialization in the debugger and see what is happening?
4. Can you post your initialization code?

I'm getting my head around the Keil debugger, so please be patient ;)

1. Yes I'm using S110 (LEDs toggle fine, btw if no radio init is done) 2,3) How do I check for / do that?
2. It's the same as the stock example from the SDK Many thanks!

Hopefully #2 is answered in your other question. For #3 you can set breakpoints as the initialization goes on and see if you get to that point. You have to be a bit patient because once the soft device is started it doesn't react well to breakpoints and you have to reset your application after each breakpoint.
