I have Sierra USB modem connected to TX1 devkit with R24.2.1. As recommendation from vendor i have installed Gobinet and Gobiserial drivers which created ttyUSBx and qcqmi0 nodes. Also GobiAPI(QMI) provided from Vendor able to talk with modem. Once i enabled the data session and try using ping, am not getting any reply messages. Same when I install drivers and APIs in my local ubuntu PC it works fine.
Following are the host setup requirement:
The Linux distribution may have in built drivers and applications that can interfere with SDK process’s
execution. The below Qualcomm drivers, if present, need to be black listed.
Please black list them as below (example is for Ubuntu). Add the 2 entries to the
“/etc/modprobe.d/blacklist-modem.conf” file and restart the host
“Modem Manager” is another application that can interfere with the SDK’s operation. Please remove it
and restart the host. Below example is for an Ubuntu PC:
#sudo apt-get remove modemmanager
#sudo killall -9 modemmanager
In wireshark, am able to see ICMP reply from 188.8.131.52 but somehow it is discarding in TX1. Also i have checked the packets via tcpdump, and packets am seeing as below when i give ping 184.108.40.206:
