Test APP
The Bluetooth V4.2 BLE RS232 adapter will link with OS
platform, ex. iOS, Android, Windows or etc.. The data bit,
baud rate, parity, stop bit, flow control, central or peripheral
will be configured by the command, DIP switch or APP. The
adapter will support small to medium quantity of data. The
continuous bulk data transmission is not available for the
The Bluetooth V4.2 BLE support the GATT service. The
profile is different with the V2.1 SPP, serial port profile. It will
need the APP. The sample code will be offered with the
2. AT command via RS-232 interface (Please check the user manual)
3. APP via GATT service
