I was able to connet to my new 4.2" ESPaper Plus Kit (SSID: ESPaperConfig; http://192.168.4.1) and entering my WiFi Credentials. But I am stuck here. According to the instructions, my screen should Change and show me the Registration Code for Pairing with the Account. But nothing happens! I only can turn off the device, hold the left Button pressed and turn it on again. It then starts again the AccesPoint (SSID: ESPaperConfig) where I can open the Config Page at http://192.168.4.1. It shows my previously entered credentials, but that's it. I tried all of the three buttons "Save Config" (obviously), "Reset Firmware Settings" (sets everything to default) and "Restart ESPaper" (does nothing, same as pressing the right Button).
Tried different WiFi's. No luck either. My WiFi is 2.4Ghz (Channel 2), with visible SSID, with WPA2 encryption.
An older Espaper 2.9" I got running (Years ago )
What shall I try next? Can I get some Debuginfos on the Serial Port? Or is the Hardware sort of DOA (Dead on Arrival)?
