Dual SIm switching using GPIO6 pin

1

hi everyone,
Iam trying dual sim switching in my WP76XX module , by using GPIO6 pin to switch to external SIM_2
by using AT Commands , but iam unable to configure my gpio pin to switch to external SIM_2
the gpio configuration which i want is +WIOCFG=6,3,1,1,3 to switch to SIM_2 in my Modem using wp76xx , iam attaching the snap shots of the commands which ive used and the response which ive got iam unable to configure my GIO6 pin to switch to external sim_2 as there are two external sims External sim_1 and external sim_2 currently iam in external SIM_1 mode i want to switch to external SIM_2 MODE , by using at commands or linux commnds please if someone could help me with this .

Any help would be aprreciated!!

This is my sim slot 1

OK

i wanted to configure gpio6 to switch to external sim slot 2
but unable to configure it is throwing error

AT+WIOCFG=6,3,1,1,3
ERROR

root@swi-mdm9x28-wp:~# echo 6 > /sys/class/gpio/export
sh: write error: Operation not permitted
even iam unable to export gpi6

Please if someone can guide me how can i do external dual sim switching using at commnds it would be a great help !!

I tried on WP7608 FW R13, I can use AT+KSIMSEL to switch SIM:



at!custom?

             IPV6ENABLE         0x01

if I used the following, I can also control the state of GPIO6:


at!entercnd="A710"
OK
at!custom="EXTUIMSWITCHEN",1
OK
at!reset
OK


//GPIO6 low state
at+ksimsel?
+KSIMSEL: 1

OK
//GPIO6 high state
at+ksimsel=2
