Dear Nordic,
I met a problem while using nRF24L01+ about MAX_RT interrupt.
In my codes, I disabled RF HW retransmit (hal_nrf_set_auto_retr(0, RF_RETRANS_DELAY);) because...
Hello,
From the datasheet of nRF52840, I found the 32MHz crystal's package is 2016 (reference circuit).
Is it necessary? Can I use bigger package?
Thank you.
