GPIO25 and INT1 in Q26CL702


#1

Hi everybody,

I have this problem with a Q26CL702 modem with following configuration

“DWL”,“V08b13”,"",“Sierra Wireless”,55344,“111611 18:03”,“dda36757”,“00010000”
“FW”,“FW_SRC_747_8_F4_3.Q2687G”,“R7.47.4.201208311102.Q26CL702”,“Sierra Wireless”,2221264,“083112 11:02”,“6aa633a2”,“00020000”
“ROM”,“800000”
“RAM”,“200000”
“DWLNAME”,“Q26CL702”

I would like to switch GPIO25 which is multiplexed with INT1 to use it as interrupt pin or digital input.

If I give:

at+wipc=1,“INT1”,2,2,1

then GPIO25 disappears from GPIO list (retrieved with command at+wiom=2).
To me, that’s correct.

If I try to release INT1 with command

at+wipc=0,“INT1”

The GPIO25 is not restored anymore in the GPIO list and I can’t use

at+wiom=1,“GPIO25”,0

command, which reply +CME ERROR:501. The only way to restore
GPIO25 in GPIO list is to power cycle the modem.

Is there any reason for this behaviour?

Thank you!

Best Regards

Hi,

I think your observation is expected.

Please refer to AT command guide section “22.4.6. Notes”.
