Describe the bug
I'm setting up an AP from Nic on Tindie which I got along with some of his tags.

The AP came with 2.01b already installed, but I'm having trouble getting it to send any images to tags.

Looking at the logs, and using the ESP Editor filesystem browser, it looks like the .raw image buffer files are empty. Here is a log from me configuring a tag in the AP to show the current date:

14:33:36 File has size 0. //00000283A43D3B10.raw
14:33:36 {"errMsg":"File has size 0. //00000283A43D3B10.raw"}

  • first, try some simple content, like 'count hours'. Does that work?
  • if you try to upload your own jpg, make sure it meets the specifications: exactly the right resolution (296x128), baseline (non-progressive), full color (not grayscale).

Same thing if I switch it to Count Hours:

I connected the AP to my computer and used install.openepaperlink.de to get the console, and when I hit Save on the tag I see:

DB saved 90ms
Failed to allocate buffer

I reflashed it just in case, using the ESP32_S3_16_8_YELLOW_AP firmware, still seeing the same thing. Here is a boot log - maybe there is a fault on my hardware?

Yes, looks like a hardware issue. I see you opened an issue on the AP-v3 github too. I'm answering there, closing this one.
