ble_app_hrs working in nRF sdk 11 but not working in sdk 12.3

[Atul Bansal]

Hello all,

I have a custom nrf51822 board with me and I am trying to flash it with ble_app_hrs example. I tried both sdk 11 and sdk 12.3 and used the softdevice s130 as stated in the compatibility matrix given in this link :- http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf51%2Fdita%2Fnrf51%2Fpdflinks%2Fnrf51_comp_matrix.html

I have not done any changes to the  code whatsoever. It is working fine with the sdk 11, but with sdk 12.3, it is getting compiled and flashed, but I cannot see the output in my nrfConnect app. 

What could be the problem here?

Also, I tried doing it with all the subversions of sdk 12 and I could find only sdk 12.1 was working. 12.2 and 12.3 were not showing any output.

Thanks

Atul

Hi Atul.

That sounds strange. I have no issue with the HRS example in SDK v.12.3.0.

Are you using the HRS example provided in SDK v.12.3.0? Or are you trying to use the HRS example from SDK 11 with SDK v12.3.0?

Have you tried debugging to see if you can get any hints to what might be the issue?

Best regards,
Joakim.

I am using Keil to compile the examples. To answer your questions, yes, I am using the HRS example provided in SDK v12.3. And when I try to debug, I see that the PC is stuck at the memory location 0xFFFFFFFE. Do you think that I am having problems because I am using a custom board with nrf51822 chip?

The custom board which I am working on has a serial input port, therefore I am using a PCA10040 board to flash it. I can detect the chip using the nrfgo studio, so I don't think I did any mistake in that, but I wanted you to have a full idea of the framework on which I am working on.

As there is no issues running the examples on the nRF51 DK, I would assume the issue is with your custom board.

There is a lot of Q&A's on devzone regarding issues with running SDK examples on a custom board. I would suggest that you take a look around.

Maybe adding some more information about your custom board will help make sense of why the example isn't working for you.

Best regards,
Joakim.

Also, you can take a look at the migrated example I uploaded to your other post.
