I added uart service ( here and here )
and I think in part of ble everything goes well. I have blinking led1 and can see all my services.
Then I tried add uart part.
After...
I have a custom board that has a nRF52832 device (receiver).
I am scanning for remote beacons (also custom boards with nRF82832).
The result is that I obtain the MAC of...
Hi I use 4 characteristics in peripheral and central. When I write to one of the characteristics in the peripheral, I read it using sd_ble_gattc_read in the central. But,...
