This blog series was created as an attempt to fill in the gap between how Bluetooth Smart is described in the spec and how you can use our APIs and event from our softdevice to do what defined in the spec…
Important updates:
Due to erratum 84 (COMP: ISOURCE not functional), capacitive sensing using the relaxation oscillator method is not usable in a real product with the nRF52832, as it will only work reliably…
