pca10056e example on nrf52811 failing at ble_stack_init()

[CraigE]

I loaded up pca10056e ble_app_beacon example for SES to test it on a custom nrf52811 device I have built (using BMD-360 module).

I followed the instructions here and removed the appropriate preprocessor symbols, then loaded it onto the board.

Using some breakpoints in debug mode I can see that it will run up until the ble_stack_init() function is called in main, where it presumably has an error and enters an infinite loop.

I'm not sure what's wrong, since it will run fine on the nrf52840 DK.

Hi,

Have you included the 32.768 kHz low-frequency crystal on your custom board? If not, you need to change the configuration to use the internal RC oscillator, as it seems that it is not integrated into the BMD-360 module.

Best regards,
Jørgen

That was it, thank you!

Seems like the main downside to using the internal RC oscillator is just a slight increase in current draw, which I can deal with for now!
