Hi!
I have noticed strange problem with one of GPIOs - P0.15. We have tested 50 devices based on nRF52832 and 3 of them have problem with P0.15 after few days.
P0.15...
The default I2C address of my sensor is 0x29 (7-bit).
If the least significant bit is low (0x52) the message is a master write to the slave. If the lsb is set (0x53) then...
