@IFTEKHAR-HASAN It appears as though you're on SDK 0.9. Since then we've released SDK 0.9.5.
However, I'd recommend loading an even newer voxl-modem package from here:
http://voxl-packages.modalai.com/dists/qrb5165/staging/binary-arm64/voxl-modem_1.0.4_arm64.deb
This one hasn't made it into an official SDK release yet but contains the quectel-CM updates I mentioned earlier.
