Remark
Enable scanning extended broadcast packet function, "Primary PHY" is the primary physical layer,
"Secondary PHY" is the second physical layer, and "SID" is the authentication ID.
Extended broadcast has no filtering function, and parameters of 2 ~ 6 are considered invalid.

PHY Rate
AT+PHY=?
Function Query the parameter range of this command.
Example AT+PHY=?
Return Value
AT+PHY=[1~15]
OK
Remark
1: 1M PHY
2: 2M PHY
4: 125k Coded PHY
8: 500k Coded PHY
This parameter is a bitfield, multiple PHYs can be set. For example: Setting AT+PHY=3 means 1M
PHY and 2M PHY are preferred. A setting of 15 means that all 4 PHY rates are preferred. The default
PHY is 1M PHY.
This command only takes effect in slave mode. If the slave device is connected, the parameters will
be updated immediately, otherwise, it will take effect at the next connection, and the settings will be
saved after power-off.
Remark: RF-BM-BG22A1 and RF-BM-BG22A1I only support 1M PHY and 2M PHY.
AT+PHY?
Function Query the preferred PHY when connecting.
Example AT+PHY?
Return Value
AT+PHY=1
