Remark The preferred PHY when connecting is 1M PHY.
AT+PHY=
Function Set the preferred PHY when connecting.
Example AT+PHY=2
Return Value OK
Remark Set the preferred PHY currently connected to 2 M.

Baud Rate
AT+UART=?
Function Query the parameter range of this command.
Example AT+UART=?
Return Value
AT+UART=[1200,2400,4800,9600,14400,19200,38400,56000,57600,115200,128000,230400,256
000,460800,500000,512000,921600]
OK
Remark
The default Baud rate is 115200 bps.
After actual verification, under the conditions of the maximum MTU of the 2M physical layer and the
minimum connection interval, the baud rate above 512000 bps can reach a stable transmission rate
of up to 50 KB/s.
AT+UART?
Function Query the current serial port baud rate.
Example AT+UART?
Return Value
AT+UART=115200
OK
Remark The current UART baud rate is 115200 bps.
AT+UART=
Function Set the serial port baud rate.
Example AT+UART=9600
Return Value OK
Remark
Set the baud rate as 9600 bps. The changed setting will take effect after 2 s and print the string
"BPS SET AFTER 2S..."
