nrf_gpio_pin_set() causes reset

I use set and clear for pins definition in other functions, far away from advertising calls. So this can't be a problem :(

@Spirit I found I had to wait a bit after starting to advertise before I did the GPIO stuff. I just put in a call to nrf_delay_ms() in between, I think.

@Eliot Stock Where exactly did you have a source of your problem? I have the same issue, but I can't resolve it -> nrf_gpio_pin_set cause a reset :(

You're right, it had nothing to do with the GPIO stuff. It was an assert in the soft device cause by starting to advertise and then doing stuff right after that.

Since that macro does nothing but set a bit in the output register I can see no way that could actually be the cause of a reset, unless PIN_SF_VCC_ON is 26 or 27.

I think you must be failing somewhere else. Start in the hardfault handler, are you going in there, where did you come from? If you reset, what's the reset reason (read it out of the register).

(note: you can set a pin high as soon as you make it an output by setting it high first then making it an output, although that has nothing at all to do with your issue).

most likely there is some APP_ERROR_CHECK failure somewhere else, the default behavior for this is a soft reset.

Looks like hardware issue. If that pin is not connected, does is reset as well ? What happen when that pin turns on ? I guest it switches power on something. May be you could check to see if it affects the power of the nRF chip. If the power get pulled bellow the threshold it will cause a reset.
