Description surya 2016-10-26 05:32:27 UTC

Hello,

I am trying to interface a sierra 4g modem (MC7455) with ARM(TI-am335x) board.
So, basically am using libqmi (qmicli) to access the node /dev/cdc-wdm0. 

But,am getting below error.

root@phycore-ge-am335x:~# qmi-network /dev/cdc-wdm0 start
Starting network with 'qmicli -d /dev/cdc-wdm0 --wds-start-network=  --client-no-release-cid'...

error: couldn't create client for the 'wds' service: CID allocation failed in the CTL client: Transaction timed out
error: network start failed, client not allocated

Any help will be appreciable. Thanks !!

Regards
Surya

Is there any chance you have another process using the QMI port, e.g. ModemManager? This usually happens when multiple processes try to use the port without using the "qmi-proxy" setup.
