EM74XX how to connect to internet with LTE in Linux?

Hi,

My EM74XX use Gobi drivers, and it has /dev/qcqmi0&1.(Sim card is 4G type)
I try to use QMI SDK “Connection_Manager”, but it always failed.

Anyone gives me some suggestions?
Thanks.

BRs,
Allen

Alan,

Define ‘failed’? What is the host you are using? An ubuntu machine? I presume you have rebuilt it for your target? What is the command line you are using to start it? If you are getting an ‘Unable to detect unit…’ (or something like that) then it means your user profile does not have read/write access to the qcqmi ports, either log in as root or send ‘chmod 777 /dev/qcmi*’.

Regards
