Firmware upgrade for UBLOX SARA-R410M-02B

A new version of the firmware is available: https://www.u-blox.com/en/ubx-viewer/view/SARA-R410M-02B-03_PCN_UBX-20058104?url=https%3A%2F%2Fwww.u-blox.com%2Fsites%2Fdefault%2Ffiles%2FSARA-R410M-02B-03_PCN_UBX-20058104.pdf

Several things to note:

  1. “Old modules, this means modules running previous firmware revisions (before than 05.12), can be upgraded to SARA-R410M-02B-03 firmware ONLY by using the u-blox EasyFlash tool. It is NOT possible to upgrade those modules over-the-air using FOTA or FOAT methods.”

  2. CellLocate is listed as a new feature.

This firmware update went smooth on a Mikroe modem with direct USB connection.

  1. Install Qualcomm usb drivers
  2. Place “SARA-R410M-02B-03-L0.0.00.00.05.12_A.02.19_IP.dof” in same directory as EasyFlash.exe
  3. Plug modem into USB
  4. Open EasyFlash and push start
  5. Wait until it tells you to power on the modem
  6. Push board mounted pwr_on button
  7. Let it finish

Thanks for posting this. We’re aware of this as well and doing some testing on our end with the new firmware.

I tried out CellLocate. I must not have had enough towers, because it gave me a nominalized Lat/Long that was in the wrong part of the country… To be fair, it also gave me a very large uncertainty with the Lat/Long.

Where can I download the SARA-R410M-02B-03-L0.0.00.00.05.12_A.02.19_IP.dof file? The PDF has a link for the EasyFlash application but it only makes references to the dof.
Thanks

Awesome thanks, it took a few attempts to figure out the credentials :wink:
