@soky157 That is not the code, it's the ID of the M5Stack device, if it's connected to your WiFi network you should see the code if not then it's in AP mode, you should look for the access point with the name M5-XXXX connect to it and navigate to 192.168.4.1 and enter your wifi credentials, then your M5Stack device will get connected to the WiFi and will show you the API KEY code
