wifi-gbp-emulator | GameBoy printer emulator which provides the received data

It's a good idea to follow the detailed beginners guide For uploading the Filesystem to the ESP you require the SPIFFS Arduino IDE Plugin. Follow the installation instructions here Before compiling the project you need to create a config.h inside the project folder (config.h.sample.txt should be used as a reference) If you run the default setup (similar to the WiFi-Printer) that file can be left empty If your (hardware-)setup is different you can adjust the parameters there.
Wifi setup can be done via a file conf.json in the /data/ folder The basic format are as follows:. All config options are optional. Change the name by which the printer will be accessible via Bonjour/mDNS. AccessPoint config Enter ssid/psk to open an accesspoint different to the default one. Array of objects with keys ssid/psk The first reachable network in that list will be used to conect to ⚠ Do not use more than 10 elements. Otherwise you might see an "Out of Memory" error in the serial monitor.
The following will describe the "raw" interface for updating ther configuration. You will only need this if you decide not to use the existing web-interface. calls to /wificonfig/get delivers the actual config (passwords are omitted). calls to /wificonfig/set will update the sent properties make sure to send the data as a JSON string in the POST-Body.
Networks are based on the ssid-property
Existing networks do not have to be sent if they should remain unchanged.
If the update for a network contains "delete": true, the networek will be deleted
If the update for a network contains a psk it will be updated otherwise left untouched
