Hello, I noticed that you were using SDK 11 and just wanted to add this version does not implement the workaround for the following errata: [108] RAM: RAM content cannot be trusted upon waking up from System ON Idle or System OFF mode. This errata can lead to the same type of behavior on affected devices.

Edvin,

Thanks for the reply. Adding your code at the beginning of ble_stack_init() yielded both clocks starting as normal.

Hello,

If the softdevice functions are not responding, then it may sound like there are some XTAL issues. Do you have an external LFXTAL? And is it working?

Can you try to jump over the "advertising by jumping over the code", as you described, and replace it with something like this:

    NRF_CLOCK->TASKS_LFCLKSTART = 1;
    while (!NRF_CLOCK->EVENTS_LFCLKSTARTED)
    {
        // Wait.
    }
    NRF_LOG_INFO("LFCLK Started.");
    
    NRF_CLOCK->TASKS_HFCLKSTART = 1;
    while (!NRF_CLOCK->EVENTS_HFCLKSTARTED)
    {
        // Wait. 
    }
    NRF_LOG_INFO("HFCLK Started");

What does the log say? Are the clocks started?

Best regards,

Edvin
