I have not managed to reproduce that here. So if I understand this correctly, the HF crystal becomes stopped after calling nrf_gzll_enable()? Do you see the same if you try the \examples\proprietary_rf\gzll\gzll_ack_payload\pca10028\host_ack_payload example?

Hi,

Does the crystal start if you write directly to the clock register from the application?

    NRF_CLOCK->TASKS_HFCLKSTART = 1;
    while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0);
