Using DSR1,DTR1,DCD1,RI1 and UART1 simultaneously


#1

Is it possibleto use DSR1,DTR1,DCD1,RI1 as GPIO’s and still be able to talk to the unit via UART1 (RXD1,TXD1,RTS1,CTS1) simultaneously? The hardware associated with this question is WMP100 or Q2686H.

I’ve had a look at the ADL guide and the AT guide, and I don’t see any mention of this.

Hi RobS,

In order to use all those GPIOs the Uart1 port must be closed (AT+WMFM=0,0,1) and unsubscribed. Otherwise you cannot subscribe to those GPIOs. In other words: it is unfortunately impossible to use both at the same time.
