We have the same problem with WP8548 (on MangoH Green, primary CF3) and WP7502 (on our custom board). Using ‘cm sim select’ command we can’t switch to EXTERNAL_SLOT_2. E.g.

SIM card is absent (LE_SIM_ABSENT).
root@swi-mdm9x15:~#
But when we reboot the board with the EXTERNAL_SLOT_2 selected, ‘cm sim info’ gives us meaningfull information (after reboot completed), ‘cm sim’ reports READY for the second slot and we can establish a connection using ‘cm data connect’ command. When we switch from SLOT_2 to SLOT_1 and back then SIM 2 is reported as ABSENT again (until next reboot). SLOT_1 is always reported as READY.
Could anyone help? Is there a tricky command sequence?
Habib. Thank you for your reply.
In my first message I wasn’t clear enought. So let me clarify. I have a mangOH Green board with WP8548 installed in a primary CF3. I also have 2 SIM cards installed (for 2 different mobile network operators: Megafon and Tele2 - they work in Russia) in two different UIM sockets on my mangOH board. I DON’T physically switch/remove/reinstall those SIMs during my work. I’m just trying to switch between them with “cm sim select EXTERNAL_SLOT_*” commands. The problem is that I can’t switch to EXTERNAL_SLOT_2 without power cycling the board: “cm sim” reports “LE_SIM_ABSENT” for the second slot.
So if you (or someone else on this forum who have a mangOH Green board with a WPx5xx and 2 SIMs installed) could run few commands through SSH on your mangOH Green board and post results here I would be sooo happy! Here are these commands: cm sim select EXTERNAL_SLOT_1 cm sim cm sim select EXTERNAL_SLOT_2 cm sim cm sim info
By the way. I’ve found out that I still CAN switch between SIMs through AT-commands. So strange.
Habib,
Thank you so much! One more thing to verify. Do you use a custom build firmware or downloaded one? I use a downloaded: root@swi-mdm9x15:~# cm info firmware
SWI9X15Y_07.12.14.00 r34472 CARMD-EV-FRMWR1 2017/11/29 18:24:42
Just a quick update.
I’ve updated legato framework on a target (WP8548/mangOH Green) to the latest version so far - 18.05. It still reports LE_SIM_ABSENT for the second SIM but I can connect with ‘cm data connect’ command (after the second attempt though). That’s a big step further!
hi when i select the sim 2 slot receiving the message as unable to select
the command issued is cm sim select EXTERNAL_SLOT_2
the response is Unable to select ‘EXTERNAL_SLOT_2’.
can any one guide me how to select the SIM Slot 2 and the firmware version used is SWI9X07Y_02.18.05.00 000000 jenkins 2018/07/19 17:40:21
