Hi All,
I'm having trouble running one of my I2C sensors connected to the nrf52 when running at a 200hz sampling rate.
Interestingly enough, the same sensor seems to...
I mean what kind of header information and stuff besides the data. I could only find this for advertising packets.
A graphic or list like this would be nice:
