Dual SIm Switching in WP76XX

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 .

Can you control the state of goio6 with +ksimsel now?

3

no iam unable to control the state of gpio6 with ksimsel because

if i keep +KSIMSEL=2 it must switch to SIM_SLOT_2 which is not happening , and also iam unablle to configure GPIO6 to switch to external SIM_SLOT_2

4

It is going to external sim switching mode but only slot_1 iam unable to switch it to external sim slot_2

5

Is this the same in fw r13 or r16?

BTW, why do you want to set “AT+WCIOFG=6,3”?
According to AT command guide, this should be for GPIO4:

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

Thank you for your kind reply. We also using WP7608 FW R13 only. we hope this works

On my side , i can use +ksimsel=1 to switch to SIM1.

Are you seeing the same AT command log as mine?

9

yes, iam seing the same AT command log as yours and iam able to switch to SIM1 too but i want to switch to my external sim_2 as shown in the above image of 2 external sim cards , i want to use the second sim interface which iam unable to the +KSIMSEL=2 is not working …

then have you tried the following to set GPIO6 as GPIO usable in linux?

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


root@swi-mdm9x28-wp:~# echo 6 > /sys/class/gpio/export
root@swi-mdm9x28-wp:~# echo out > /sys/class/gpio/gpio6/direction
root@swi-mdm9x28-wp:~# echo 0 > /sys/class/gpio/gpio6/value
root@swi-mdm9x28-wp:~# echo 1 > /sys/class/gpio/gpio6/value
root@swi-mdm9x28-wp:~# echo 0 > /sys/class/gpio/gpio6/value

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