I brought my espaper2.9 to get it up and running again, and in the process of troubleshooting wifi connectivity removed the device from the espaper.com registration and reset teh firmware.  I am able to connect to wifi now, and it does appear to be hitting the espaper.com endpoint, however the screen stays blank and I am not able to get a claim code to create a new registration for the device.  I tried using teh device ID from the serial watcher (and a few other things like mac address) but can't seem to reestablish the registration :(

I doesn't look like you have any devices registered currently. Can you please make the output on the serial console available here (redact WiFi credentials). In case it's not contained there please also report the device MAC address.

The only thing that sticks out so far is the "Bmp has wrong bit depth. Device: 1, bmp: 0" and the apparently different file sizes (transfer vs. SPIFFS, 4742 vs. 3811). Everything ok on the server side.

Are you building and flashing with Arduino IDE or Platform IO? Can you please share your EspaperClient/settings.h and platformio.ini files?

That looks just fine. What are your board/flash settings in Arduino IDE? Make sure you use  Flash Size "2M (512K SPIFFS)".
by (120 points)
I originally had it at 2M (1Mb) but found the support article in the forum where it gets stuck at flashing, and set it to the 2M 512K as you indicate. I also did a fresh download.   This is the OCR of the tools menu

I tried a couple of different things, starting with moving back on the esp8266 library from 2.5.2 to 2.5.0.  I also changed to test.espaper.com with the define in settings.h, and was able to connect and got the registration experience.  I reflashed, reverting off test and was able to connect and register the device on www.espaper.com.  Looks to be working correctly now.
