Hello everyone, I’am using EM7565 in production environnement, We are experiencing issues with two identical setups, the modem gets reset after few hours of uptime (from hours to days), In the linux logs, we observe a disconnection on the USB port : [259892.516755] usb 1-3: USB disconnect, devic…

Have you tried the latest FW 01.14.13.00

Hello, no I didn’t, I’ve checked the release notes but it’s unclear for me if there are any changes that could solve the issue I’m facing, Would you recommand to update the modem ? As the system is in production modem update could be difficult to achieve, In the past to update the modem we were u…

Does this help to use qmi-firmware-update? [image] Updating EM7565 on openwrt MC/EM Series Here’s what I’m doing. root@OpenWrt:~# qmicli -d /dev/cdc-wdm0 -p --dms-set-firmware- preference="01.09.04.00,002.019_000,GENERIC" [/dev/cdc-wdm0] Firmware preference successfully…

The update process is now clearer to me, Do you have any comment on the crash report ? Before updating the modems I need to be sure the process have a chance to fix the issue, By the way we have an other identical setup on the same area facing the same issue with a very similar crash report : AT!…

no, i don’t know if the new FW can solve the problem. Just see if there is some luck on this If you are using verizon, you can also try the newest FW SWI9X50C_01.14.20.00 https://source.sierrawireless.com/resources/airprime/minicard/75xx/em_mc75xx-approved-fw-packages/#sthash.0IAOmDbB.dpbs

Hello again, As you suggested, I’ve upgraded the modem to the version 01.14.13.00 using qmi-firmware-update, Unfortunately, the error still occurs, with a similar crash report : AT!GCDUMP Src: FatalError File: rflte_dispatch.c Line: 5397 Str: rflte_dispatch_handle_act_deact failed 00000000 000…

Can you try with newest FW SWI9X50C_01.14.20.00 with VZW PRI and see if you can register network after changing the APN in AT+CGDCONT?

At first sight this sounds complicated to execute as I don’t have physical access to the system, I will first try on a identical system I have in our office and will come back to you,

I successfully updated on of my test setup to the FW SWI9X50C_01.14.20.00 with VZW PRI, after what I reconfigured the APN in order to connect the modem to the internet, However the modem is connected to UMTS only (no LTE connection) with very poor bandwith, Thus I’m not confident in updating my pr…

which carrier PRI are you using before? GENERIC? I can put here to let you have a test As said before, I don’t know if it can fix or not, just doing trial and error with new FW.
