I need to change the state of a GPIO pin (GPIO1) on a SL8083 module using the AT serial interface
The problem is any AT+WIOM commands just return and error.
AT+WIOM=2 should list all the current status of the GPIO’s
AT+WIOM=1,“GPIO1”,1,0 should set the GPIO1 to an output with a value of 0
Both commands just return ERROR
What am I missing?
PS The firmware version is
Manufacturer: Sierra Wireless, Incorporated
Revision: S2_0_0_19AP R1003 CARMD-EN-10527 2011/07/12 14:02:20
IMEI SV: 3
3GPP Release 5
Do I need to download anything to enable these commands
