Thanks for your response! Yes, I have an error code as below:

<error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM] at ../../../main.c:384

PC at: 0x0002F0DB

After looking at this more closely I re-verified the softdevice loaded using nRF connect for MacOS to read back the memory and it turns out the s132 softdevice was loaded and not s140 as expected. I discovered the build script didn't update the softdevice automatically, only the application. So with the correct softdevice loaded, it worked. Sorry for any confusion and thanks again for your help!

Hi,

Do you get any error codes? Which project did you start out with? There is no PCA10059 project for the ble_app_beacon example in the SDK, did you use PCA10056 project?

Could you upload the project for debugging?

Best regards,
Jørgen

After further reading, I thought it might be due to the wrong softdevice, but I am using the softdevice intended for the nrf52840: s140_nrf52_6.1.1_softdevice.hex. It's odd because it seems to think it's a 132 softdevice. Is there some way to verify? I used nrf connect and it seems ok.
