pin reset sequence for nRF52832

[ogura]

For pin reset, do I need to drive it low after it goes high once during power on sequence? or it does NOT need to be high before drving it low.

I'm not sure what you are trying to achieve. Please give me more details.

after VCC_NRF up, advertising does NOT start. so I need to do PIN RESET. P0.21 is pulled up in IC and it goes up after power up. How long do I need to do PIN RESET after RESET PIN after power up. in my experiment, I need to wait for e few sencond to make pin reset work.

Hi,

The RESET pin must be held low for a minimum of 0.2uS in order to generate a valid reset event.

If you are having trouble with the application starting when starting up, try to add the -r argument when programming the .hex with nrfjprog. nrfjprog -f NRF52 -r
