And also, for GATT_Server, GATT_Client it can be Central or Peripheral. (As I manually set it.)
And also, the...
hi
I am using nRF51822(from waveshare). previously i was able to program my device with nRFgo Studio. But I am facing a problem now. I programmed my device with radio transmitter...
I want to collect data for analysis sent from peripheral(ble_app_uart example), I connected peripheral device to app(nrf connect) and enabled service, now the data is sent...
