Application examples
We used nRF Connect, an APP provided by the Nordic company, to test the sending and
receiving of data between mobile phones and BLE serial port adapters.
1.
The BLE serial port adapter keeps the factory default parameters and connects to PC through the serial
port. Power on and enable it in the data communication mode.
2.
Open the "nRF Connect" software and the phone will search the BLE Bluetooth devices nearby. The
device name "BLE0405C1P" will be shown, which is the default name of the BLE serial port adapter.
