Can't Send APDU: Error executing command: error: operation failed: Unknown status 0x87430003

[bam80]

The modem is Fibocom L860GL-16.

Logic Channel seems successfully open but then Send APDU: part fails, I tried different commands:

Also, if I open the Channel manually and then try to immediately close, it fails:

 $ mbimcli -d /dev/cdc-wdm0 --ms-set-uicc-open-channel="application-id=a0000005591010ffffffff8900000100" 
Succesfully retrieved open channel info:
	  status: 144
	 channel: 1
	response: (null)

$ mbimcli -d /dev/cdc-wdm0 --ms-set-uicc-close-channel="channel=1"
error: operation failed: Unknown status 0x87430003

What could I else try to diagnose it?

[stich86]

have you tried using -p on mbimcli?

[bam80]

I stopped the ModemManager and had to remove the -p option from the script as otherwise it doesn't work:

$ mbimcli -d /dev/cdc-wdm0 --ms-set-uicc-open-channel="application-id=a0000005591010ffffffff8900000100" -p
error: couldn't open the MbimDevice: Couldn't spawn the mbim-proxy

eSIM is working under Windows?

[bam80]

I didn't try particular exemplar yet, but overall it does.
Don't have Windows on hands, might have tomorrow.

[stich86]

Succesfully retrieved open channel info: status: 144 channel: 1 response: (null)

I don't see response here.. are you swapped slot to use eSIM one?

[bam80]

Yes, otherwise, it can't open the Channel.

[stich86]

but you should get an APDU response and it doesn't reply, that's very stange..

[bam80]

So you think Windows won't help here?

[stich86]

if you can test this module on Windows it's better, just to see if the eSIM can be accessed and profiled

[bam80]

If it works on Windows, do you know some USB sniffing techniques to debug it?

[bam80]

So I've got the Windows for two days, and apparently eSIM does work there.
I don't have any eSIM profile to test completely, though.

But I can enter "Manage eSIM profiles" screen, see EID there and QR code with eSIM properties, and can "Add a new profile".

If you have any other test procedure in mind, please let me know.
Thanks.

eSIM is working under Windows?

@stich86 Yes, at least I can add a profile:

recommended, you contact fibocom FAE engineer.
this a mobile module cannot close the channel, i think it is a firmware bug.

[bam80]

@septs as you see above this module works on Windows perfectly fine
