6.2 General Purpose Input/Output port
/!\ Important notice: The following commands are from Generic AT command guide and will work only
if the Maestro SmartPack is disabled (AT+SPMODE=1). Else please refer to the SmartPack user manual
to control GPIOs through SmartPack AT commands.
This port can be configured as either an input or an output and is mapped to GPIO1 in the internal micro-controller.
– To setup this port as an input, type AT+WIOM=1,"GPIO1",0 on the serial port. Then to read the status of
the input, type AT+WIOR="GPIO1" . +WIOR: 0 means input is below 0.8V, while +WIOR: 1 means a positive
voltage higher than 2V and no more than 3.3V. Higher voltages will damage the unit.
Note: Please note that the input port is put by default to High status internally, so you just need
to short it to the ground to make it low, and open to make it high.
See below example:
AT+WIOM=1,”GPIO1”,0 ;Configure as input
AT+WIOM=4 ;Save configuration
AT+WIOR="GPIO1" reWIOR: 1 ;Just leave I/O pin open
AT+WIOR="GPIO1" reWIOR: 0 ;While shorting I/O to ground
