Procedure to Upgrade –L4E1 cellular radio firmware to version 676
Prerequisites: a. The gateway should have SSH enabled via ethernet LAN in order to copy the firmware to the unit. b. The gateway /tmp should have > 110MB space available. c. Disable cellular on the UI if it's in WWAN mode. Step 1: copy the LE910C4-EU_25.20.676_CUST_069_perf_STR.bin,l4e1_flash and uxfp files to /tmp using a program like winscp or Filezilla. ( a zip of these 3 files can be found here : http://www.multitech.net/developer/wp-content/plugins/download-monitor/download.php?id=63 or here http://www.multitech.net/developer/downloads/#lr4e1-cellular-radio-firmware) Step 2: verify that that you are on a lower version of radio module firmware sudo -s radio-cmd at+gmr if it returns 25.20.673 then you are good to proceed to step 3. if it comes back with "M0F.670006" then it's already upgraded and you don't have to do the below steps. Step 3: Login through ssh using program like putty and then copy l4e1_flash and uxfp from /tmp to /home/root (password same as the admin password to elevate previlages to root) cp /tmp/l4e1_flash /home/root/. cp /tmp/uxfp /home/root/. Step 4: check file permissions if not executeable and owned by root do: chmod 755 /home/root/l4e1_flash chmod 755 /home/root/uxfp chown root:root /home/root/l4e1_flash chown root:root /home/root/uxfp Step 5: upgrade firmware /home/root/l4e1_flash /tmp/LE910C4-EU_25.20.676_CUST_069_perf_STR.bin Step 6: After the device reboots login via ssh and verify that the upgrade was successful. sudo -s radio-cmd at+gmr The command should return the value M0F.670006 Cleanup: Remove uxfp and l4e1_flash scripts from /home/root sudo -s rm -rf /home/root/l4e1_flash rm -rf /home/root/uxfp ------------------------------------------------------------------- Here is an example run to show how the output should look like: mtcdt login: admin Password: Last login: Mon Jun 29 21:18:29 UTC 2020 on ttyS0 admin@mtcdt:~$ sudo -s Password: root@mtcdt:/var/config/home/admin# radio-cmd at+gmr 25.20.673 OK root@mtcdt:/var/config/home/admin# cp /tmp/l4e1_flash /home/root/. root@mtcdt:/var/config/home/admin# cp /tmp/uxfp /home/root/. root@mtcdt:/var/config/home/admin# chmod 755 /home/root/l4e1_flash root@mtcdt:/var/config/home/admin# chmod 755 /home/root/uxfp root@mtcdt:/var/config/home/admin# chown root:root /home/root/l4e1_flash root@mtcdt:/var/config/home/admin# chown root:root /home/root/uxfp root@mtcdt:/var/config/home/admin# /home/root/l4e1_flash /tmp/LE910C4-EU_25.20.676_CUST_069_perf_STR.bin l4e1_flash: executing this l4e1_flash: Attempting to Flash...This might take upto 15mins.
