I was having a few issues and noticed that Buildroot did not include the latest ( 1.18.0 ) version of libqmi so I upgraded that. Things seem much better after that, but now I am getting intermitant errors when trying to use the "qmicli" and "qmi-network" commands. These are the two typical errors I am seeing: 1) # qmicli -d /dev/cdc-wdm0 --nas-get-signal-strength [28 Jun 2017, 13:44:37] -Warning ** Error reading from istream: Error reading from file descriptor: Input/output error error: couldn't create client for the 'nas' service: CID allocation failed in the CTL client: Transaction timed out # qmicli -d /dev/cdc-wdm0 --nas-get-signal-strength error: couldn't create client for the 'nas' service: QMI protocol error (3): 'Internal' # qmicli -d /dev/cdc-wdm0 --nas-get-signal-strength error: couldn't create client for the 'nas' service: QMI protocol error (3): 'Internal' 2) # qmi-network /dev/cdc-wdm0 status Loading profile at /etc/qmi-network.conf...

Has anyone come across these errors, or can give me any tips what could be wrong or how to help diagnose the issue further? Thanks in advance.
