Thanks for that hint! I my case the problem was caused maybe because of stack overflows within freeRTOS tasks. The problem disappeared when I adjusted the stack size parameters.

I encountered the similar issue and finally found that there is an Macro declaration in nrf_drv_config.h that limited an array size that handling gpiote user registration. The macro is GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS which is set to a value of 4. However, it is due to the SDK has already registered 4 buttons, the array has used up.

So channel_port_alloc returns NO_CHANNELS. If you examine channel_port_alloc(), can you figure out why?

Thanks for commenting! The code does not fail in that, I just edited the question to show where the error is hit.

Firstly, you should use the alpha version. You should use SDK 11 with S132 2.0.0.

I'm guessing this comming from:

if (m_user_count >= m_user_array_size)
{
    return NRF_ERROR_NO_MEM;
}

inside app_gpiote_user_register().

If you init with 4, m_user_array_size should be 4.
