ESPAPER 2.9" stuck at firmware upgrade in progress...

Question

Hi guy's!

I've just updated one of my Espaper and it stock at 'Firmware upgrade in progress...'

Any hints?

Thanks!

After a while, It display 'Failed to update time from internet (NTP)

This "sounds" like a WiFi connection issue. Are you in a position to hook it up to a computer to read the serial output?

Maybe that?
23:19:42.316 -> HTTP_UPDATE_FAILED Error (-100): Not Enough space

Got it. I have to put  2M (512k SPIFFS) instead of  2M (1M SPIFFS)

Now it work!

Thanks!

Even though you figured it out yourself before we could - well done! - I still write up a quick answer so we can mark this as resolved.

I took the liberty to redact your serial monitor output (replaced device id/secret with *******).

It's exactly as you said. "HTTP_UPDATE_FAILED Error (-100): Not Enough space" means there wasn't enough memory to fit the downloaded firmware alongside the existing firmware. Over-The-Air updates work by placing the new firmware next to the existing one and then rebooting from the new one. Since the ESPaper Client binary is just slightly over 500KB it needs more than 2*500KB on the device outside SPIFFS. As the client stores only small configuration files on SPIFFS it is ok that it's reduced to 512KB.

I guess you found that information at https://github.com/ThingPulse/espaper-client/#setup.
