You built it yourself? Have you flashed the C6? Button is at the bottom of the update firmware screen.

Says yellow AP there - did you choose the right option?
Update the filesystem too, its saying none there.
Does your AP have internet access ok to download the update?

Heres mine

Actually might have downloaded fine (if you see those files in the root of the file browser then its ok) - then its the connection to the C6 that isnt working. Probably because its using wrong AP config/pins, try again after reflashing with the mini ap v4 fw.

This is a hardware defect, and out of scope of the openepaperlink project ;-)
Please send the seller (that's me...) a message, and I will help you solve it.

Ah, you didn't buy a assembled Mini AP v4 on my Tindie store, but soldered it yourself? In that case, you probably don't want to use the 'OpenEpaperLink Mini AP v4' build... First identify the kind of access point you have build. Can you post a photo of your access point?

Okay that's an S3. You'll need both a C6 and S3 to make an accesspoint, just an S3 won't do :)

You should not try to use the web installer on the C6. Your ESP32-S3 is the main component, that can be flashed using the web installer. The C6-module is flashed from within the webinterface after installing the esp32-s3 (config tab -> update -> update C6).

Better! Now check your wiring between S3 and C6.
Now take a good look on your wiring, and the name of the build you did make. Hint: it's not the OpenEPaperLink_Mini_AP_v4

I followed the section on the graph for the Yellow AP / Mini AP v3 because i thought thats the closest i have to the mini ap v4 and it specifies it requires an esp32s3 so im assuming im on the right track i created this sheet so i can cut the data down to only the relevants and i can confirm the wiring is correct to the section im following?

Yes, you wired according to the Yellow AP / Mini V3. But you flashed the esp32-s3 with Mini AP v4 image, which uses other pins. The 'v3' and 'v4' are different hardware revisions, not a software version. Reflash the esp32-s3 using the right build name.
