18. Set PIO multiple port output

Command Response Parameter

AT+MPIO=<Param> OK

Param: Mask combination of

PIO ports number (Decimal)

HC-05 Bluetooth module provides the ports (PI00~PI07 and PI010) which can

extern another input and output ports to the user.

(1) Mask of PIO port number = (1<<port number)

(2) Mask combination of PIO ports number= (PIO port number mask 1|PIO port number

mask 2|……)

Example :

PI02 port number mask=(1<<2) =0x004

PI010 port number mask =(1<<10)=0x400

Mask combination of PI02 and PI010 port number=(0x004|0x400)=0x404

Example:

1. PI010 and PI02 ports output high level

AT+MPI0=404\r\n

2. PI04 port output high level

AT+PI0=004\r\n

3. PI010 port output high level

AT+PI0=400\r\n

4. All ports output low level

AT+MPI0=0\r\n
