Now I'm working with MCP 3.9.0.
When any device is connected, characteristic default values are not 0's. Can they be initialized in any way? It is a little bit annoying when...
Is there a separate reference resign for the 1.8V of operation (as in case of nrf51)? Or it's implicit and the chip can be powered in range of 1.7V - 3.6V.
Thank you!
