3.2.7. Input/Output Port Binding
This command is used to configure the user defined output-port action triggered by input ports. If
the IO combination is set and the corresponding condition appears, the device will output specified
wave shape on the specified output port. Otherwise, the device will restore the initial status of the
specified output port. And the device will report message +RESP:GTIOB to the backend server
when the logical status of bound input ports changes.
AT+GTIOB=
Example:
AT+GTIOB=gmt100,1,3,3,3,1,0,8,3,,,,,0006$
AT+GTIOB=gmt100,1,3,3,3,2,1,,,,,,,0006$
'0' – '9' 'a' – 'z' 'A' – 'Z'
<IOB ID>: ID of the user defined IO binding.
<Input Mask>: Bitwise mask for input ports composition. Each bit, from bit 0 to bit 1,
represents one digital input port. Set to 1 to enable and 0 to disable corresponding input port.
bit0: ignition detection
bit1: digital input 1
<Trigger Mask>: bitwise mask for trigger condition composition of the corresponding input
ports. Each bit, from bit 0 to bit 1, represents the logical status of the corresponding input
