Do you have the /dev/qcqmi port?
Do you integrate the slqssdk binary?

HI Jyijyi,

We have solved the above error by placing slqssdk binary in /vendor directory. And after making some changes, it’s working for us.

But now, we have following error (continuously retry…), due to which we are not able to access internet thru wwan0 interface. Also attached full radio logs for reference.

Let me know what is missing?
