EM7455 error: WDA unsupported #2

Open blee0518 opened 4 years ago

I am having issues with EM7455. I used .rules to make sure device ATTRs use qmi_wwan driver it shows in lsusb -t that modem is using these drivers. Running latest firmware update for ATT, and have tried GENERIC

When running qmi-network /dev/cdc-wdmX start I get :

error: couldn't create client for the 'wda' service: CID allocation failed ine CTL client: Transaction timed out
Device link layer protocol not retrieved: WDA unsupported
Starting network with 'qmicli -d /dev/cdc-wdm2 --wds-start-network=apn='broadd'  --client-no-release-cid '...
error: couldn't create client for the 'wds' service: CID allocation failed ine CTL client: Transaction timed out
error: network start failed, client not allocated

When I try to run Start-network manually, i get this response:

error: couldn't create client for the 'wds' service: CID allocation failed ine CTL client: Transaction timed out

If I remove the .rules file from running giving the port mbim_wwan, I have been able to run mbim-network /dev/cdc-wdmX start and get a network start successfully, but I am not able to get an IP address.

This modem would be the second modem I am running on my Debian device, the primary(working) one now is MC7455 with qmi and raw-ip. I am able to get DHCP address with this modem fine.

Can you help with fixing in either way?

Hi. I am interested in your answer. Did you succeed in?

I was able to fix. I dont have all information off hand but i had to reset the EM modem to look like a MC version. I ran a script file i found online.

I suggest reaching out to the libqmi community. And asking them they are very active. https://www.freedesktop.org/wiki/Software/libqmi/

Best of luck.
