Firmware upgrade EC25-A

I have several EC25-A USB modules. I would like to have the files required to upgrade
the firmware.

There are two versions deployed at the moment:


My understanding is that the latest version is:


Can you please provide the images required to perform this upgrade?

I am aware of the DFOTA method. Can I use the same image to perform this update or do I need separate delta files for the above versions of firmware?

If possible, can you also provide instructions to flash the firmware from a linux host that the module is physically connected to via USB?

I have sent you the latest firmware version. If the current module cannot communicate normally, you can only upgrade the firmware through USB. If you can communicate normally, you need to request the differential firmware package from and provide information of historical and required version

Thank you. The module can communicate normally.

However, I would also like try upgrading through USB. Can you please provide instructions for doing so? If firehose is required, then can you provide a precompiled binary for arm based linux machine:

Linux vs-WBAW3AQ043 4.9.126-g016c5aba1d #1 PREEMPT Fri Jun 7 18:34:42 UTC 2024 armv7l GNU/Linux

I will email support for a differential firmware package.
