Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
what's the difference between app_timer api an nrf_drv_timer
are they using separate timers or the same timers?
if they are using the same timers, can app_timer_create...
I'm trying to use app_timer without softdevice, I tried to initialise it explicitally but still not working

I have an application which uses SPI to communicate with ADC.
when I don't use SoftDevice and use nrf_drv_timer to start conversion periodically it works
but when I...
Hi,
I am using the sample ble_gls code from Nordic.
