PC Bluetooth Connection

The direct connection between PC and BLE4.1 built-in Bluetooth is not available for temporarily

(similar to smartphone, PC also need another software to realize the connection. The development

is still in planning)

Bluetooth P2P Communication

The procedure of BLE4.1 P2P connection is similar to BLE4.0, and the only difference is the P2P

mode command.

There are two devices in all, one should be set as the master device(ROLE_CENTRAL) and the

other one should be set as the slave device(ROLE_PERIPHERAL). Config two BLE4.1 devices as

P2P connection mode with AT+NETWORK=P2P (Default: P2P mode).
