Hi Chris

Good to hear you figured it out 🙂

The radio will be disabled after you have disabled the SoftDevice, that is correct.

Best regards

Dang Torbjorn!

I think you nailed it. I was calling from a NUS response handler.

Setup to call from main instead, seems good to go!

I used nrf_sdh_disable_request() from main (not a handler/callback)

I also had to dodge

```buttonless_dfu_sdh_state_observer()```

servicing the

```NRF_SDH_EVT_STATE_DISABLED```

event and shutting down the system by setting my own flag.

Appreciate the help.I assume the soft device releasing the radio peripheral would put the radio peripheral into "Disabled" state.

Regards,
Chris.

Is there any chance you are trying to call nrf_sdh_disable_request() from interrupt context?

If so, do you know which level?

If you are calling this function from main context I don't understand why it would fail.

Is your code based on one of the standard SDK examples, or is it mostly custom?

Best regards
