With teddyCloud you can also write a new image with your custom CA and a hostname/IP so the box connects to teddyCloud. If you have a Fritzbox you can set it to tc.fritz.box (see CC3200 how to configure the hostname on your Fritzbox), if not set it to the IP of teddyCloud.

Check, that your backup of your flash is okay and you were able to extract the certificates.

If you successfully read or load the flash of your Toniebox, the patching step is shown. Enter the hostname/ip of your teddyCloud instance. You can now also enter the WiFi credentials. To proceed click [Patch].

Reassamble your Toniebox again. If you already set the teddyCloud hostname, you can skip the DNS step for the ESP32, if not continue with DNS step for the ESP32.

Your Toniebox should now be able to connect to your teddyCloud. Do a freshnesscheck and check if the box appears in the Toniebox management.
