automatically reconnect. After BLE is enabled again, the automatic reconnection function
will be resumed.
If the MAC address of the remote slave device is changed, the automatic reconnection function
of this module fails.
Example
Example Query the list of reconnected devices
Instruction: AT+AUTO_CNT?
Return: +OK=NULL
Enable automatic reconnection and set the reconnection device MAC C2:01:02:03:04:05
Instruction: AT+AUTO_CNT=1,C2:01:02:03:04:05
Return: +OK
Enable automatic reconnection for all devices in the automatic reconnection list
Command: AT+AUTO_CNT=1
Return: +OK
Disable automatic reconnection for devices with MAC C2:01:02:03:04:05
Instruction: AT+AUTO_CNT=0,C2:01:02:03:04:05
Return: +OK

AT+PHY?
+PHY =[para]
Setting
AT+PHY=[para]
+OK：Succes
+ERR=[NUM]：Error
Parameters
para: The value ranges from 1 to 15
1:1 M PHY (default)
2:2 M PHY
4:125K Coded PHY
8:500K Coded PHY
This instruction can set multiple PHYs, parameters using the concept of bitfields. Simple
conversion method, such as the preferred 1M PHY and 2M PHY, the sum of the corresponding
parameters can be used as the parameter, that is, AT+PHY=3.
Descrition
Take effect immediately, power failure does not save;
This parameter takes effect in the secondary role.
If it is connected to a mobile phone, it takes effect when the mobile phone turns on the
notification.
Example
The preferred physical layer for querying connections
Instruction: AT+PHY?
Return: +OK=1
Set 2M PHY as preferred
Instruction: AT+PHY=2
Return: +OK
