2. AT+SCAN=1 master scanning started;
3. AT+AUTOCONN

6.1.1.1 Master connecting method
6.1.1.1.1 Condition filtering
The device can be configured to filter by MAC address bonding and service UUID.
UUID filtering AT+UUIDSVR
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.
6.1.1.1.2 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.
