Different from the traditional Bluetooth (such as Bluetooth headset), BLE4.1 need specified
eigenvalue and device service ID to connect smartphone. The direct connection between BLE and
smartphone device manager will lead to communication problems. Therefore, it needs a the third
party APP, such as BunoBasicDemo (published by DFRobot), BLE Device Monitor from TI .etc.
In this section, we'll take BunoBasicDemo published by DFRobot as an example.
Set BLE4.1 as peripheral device with command AT+ROLE=ROLE_PERIPHERAL. Set connection
mode as P2P by AT+NETWORK=P2P command and restart BLE4.1 (power off and restart).
Open BunoBasicDemo app, click SCAN, then we'll see the scanned BLE4.1 device .
