MC7455 and MC7430--query-subscriber-ready-status timeout

[Chris Lockwood]

Hi,

I have MC7455 and MC7430 cards. Both are loaded with SWI9X30C_02.24.03.00.

I'm using the latest git commit 5bb673fe87... but the same behaviour is observed with 5c3935b75fc4dd46...

To get these cards to connect, I first need to run --query-subscriber-ready-status, then --attach-packet-service command and then the --connect commands.

>From a clean start, first command run is:
root at avios:~# mbimcli -p -d /dev/cdc-wdm0 --query-subscriber-ready-status --no-close
error: operation failed: Transaction timed out
[/dev/cdc-wdm0] Session not closed:
                    TRID: '4'

The command takes a bit more than 10 seconds before it times out (I can see the 10 second timeout in the libmbim source).

But I can then --attach-packet-service and -connect and its all working fine. Without the --query-subscriber-ready-status command I cannot connect.

Any ideas why it might time out? It's not a huge problem but it does add another 10 seconds to the start time.


With verbose logging:
root at avios:~# mbimcli -v -p -d /dev/cdc-wdm0 --query-subscriber-ready-status --no-close
