Thank you - I now have data passing through the EM7455:
- Lenovo ACC100290 purchased from Amazon which has firmware configured for MBIM
- Linux 4.10 kernel
I got a bit hung up about the transaction id's, forgetting I needed to
leave the connection open and re-use the transaction id's for future
commands like 'query-ip-configuration'. I notice some mbimcli commands
need to make sure not to re-open and others don't. Is there a simple
rule about this?
I did find 'query-packet-statistics' never returns anything but 0's:
root at ventana:~# mbimcli -d /dev/cdc-wdm0 --query-packet-statistics
[/dev/cdc-wdm0] Packet statistics:
Octets (in): '0'
Packets (in): '0'
Discards (in): '0'
Errors (in): '0'
Octets (out): '0'
Packets (out): '0'
Discards (out): '0'
Errors (out): '0'
Thanks for your help!
