2. AT+SCAN=1 master scanning started;

3. AT+AUTOCONN configure if it is automatically connected after power on；

4. Once in manual connection，AT+CONN configure to connect specific device；

5.1.1.1 Master connecting method

5.1.1.1.1 Condition filtering

The device can be configured to filter by MAC address bonding and service UUID.

UUID filtering AT+UUIDSVR

is filtered according to the content configured by AT+UUIDSVR. The filtering condition cannot

be closed. If MAC address filtering is not enabled, the MAC matches, it is automatically connected to the slave once service UUID is

matched.

If the user needs MAC address filtering, MAC address filtering needs to be enabled through AT+BOND=1, and the MAC address

is added to the master through AT+BONDMAC. After the master scans to the slave, if it is the same as the binding list MAC address

and the service UUID, it automatically connects to the slave device.

If the master is configured as a manual connection, MAC address binding filtering will be ignored, but svruuid is consistent.

5.1.1.1.2 Automatic connection

If configured to connect automatically, the slave is automatically connected after the condition filter is met.

If configured to connect manually, turn on scanning. The master will scan the device with the service UUID matched and output

through the UART (the data format is as shown in Figure below, the master outputs the scan result data format). The user connects to

the specified slave device using AT+CONN.

RSSI(Signal quality) MAC

5.1.2 Slave

1. AT+ROLE=0 choose role as slave. Restart to take effect.

2. AT+ADV=1 configure normal advertising mode.

3. The broadcast switch is configured to be enabled. Once power on, it automatically enters the broadcast state. Otherwise,

the broadcast device cannot be found.
