Hello Nordic-Team,
I am using the SENSING mechanism on GPIOs to wake up a firmware from SYSTEM OFF. Two GPIOs are used for this and it is crucial for the firmware to detect...
The spec. gives a 22V max for a limited amount of time. And max. 5.5V as recommended operating conditions.
But I wonder, what will be "inbetween", e.g. 7V for hours?
From...
Hi all,
I'm working on BLE time synchronization between nodes using hardware timestamps via GRTC + DPPI + PPIB cross-domain. CRCOK and PHYEND work perfectly, but adding...
