RE: RTC Compare stops generating interrupts

@llyaK: I assumed you used packs for testing. The example I provided doesn't use pack. You can download the SDK from this link.

Try to compile ble_app_uart example included in the sdk, if it does, you can put the example ble_app_uart - RTC1 into the same place (\examples\ble_peripheral) and compile.

I'm unable to compile and deploy this successfully. The included project doesn't correctly link against the softdevice hex file. I get the following errors when using the provided project

Hi IlyaK,

The RTC use the LFCLK as the oscillator. But you should be fine to use the RC LFCLK for the RTC1.

I wasn't able to reproduce the issue you described. I assume you don't use app_timer library which also use RTC1 ? Attached is a project that I simply toggle LED4 on the PCA10028 board by RTC1.

The example is based on SDK v8.1
