Hi,
I have acquired an Accesspoint which seems to stem from ATC. It is a prefabricated hardware with both modules and a screen built together. The board says "@ATC1441 TLSR/C6-AP".
When I got it it had a firmware version "8.2" on it.
Now it did show "An update from version 8.2 to version 2.84 is available."
Obviously the numbering seems odd, but I tried it. Afterwards the connection to the tags was lost and I could not reestablish it. So somethings seems wrong here.

So my question here is, how do I choose the right firmware and where do I get it from?

Would it be the right path to follow the upgrade suggestion from 8.2 to 2.84 as the UI suggests?
There is a "Repo" currently filled with "OpenEPaperLink/OpenEPaperLink". Is that the right one?
Currently the "environment" is "OpenEPaperLink_Nano_TLSR_C6". Is that correct?

Anyone who could shed a little light?

Hey,

updating via the update function should work correctly of course
The repo is coorect
Also correct

Please check if the PCB holds an ESP32-S3 and ESP32-C6 or TB-05

To get back to a default state you can use install.openepaperlink.de to reflash the firmware(Nano TLSR C6), you need to press the button on the AP while pluging it in so its in bootloader mode
