Hi,

I’m searching the lastest Firmware for tle LC86G-LA with the change log

I’m also searching the method to flash the LC86G without using the flashtool, the gnss are soldered on my pcb and i can’t connect to a serial adapter. I wan to use the UART of my chip to upload and flash the GNSS (ESP32 with OTA connected in UART to LC86G

Thanks

Hello ,
I’m currently trying to integrate LC86G EVB kit. While trying to download the QGNSS tool (Version 2.2) specified in the user guide through website it states that the tool isn’t available on the website. Kindly provide any alternate download links for the same.

Also if any of you’ve tried integrating the LC86G using ESP32C6 chipset ,please provide github to access the source files for the same.

Thanks

Hi, we are using the LC86G with firmware LC86GLANR12A01S (2023/02/10).

We suspect there is an NVM persistence issue with the PPS configuration in this firmware. The 500 ms PPS setting works correctly until power-cycle, but is not retained afterward.

Could you please provide the latest available firmware for LC86G, preferably one that addresses this issue?

Thanks,
Saurabh

Hi @Saurabh_Chakrabarti,

Please check your email, I have sent you the latest firmware.

After using $PQTMCFGPPS command you can save configuration to NVM with $PQTMSAVEPAR*5A.

Best Regards, Dobrica

That command does not work on my device, old fw i guess. I’m using the $PAIR752,4,100*3F command , but I’m unable to save to NVM using the $PAIR513*3D command. But commands give success output, but on reboot the configurations do not persist

This works with the PQTM commands I used after upgrading firmware. Thanks a ton
