The response is in the format `SSID;strength\n` a double \n indicates the end of the list 28 | 29 | ### HTTP API 30 | 31 | The service exposes also an HTTP API to intereact with WIFI connections 32 | 33 | - `/connect` connect to a WIFI connection. Expects a body in the format `{ "payload": "WIFI:T:WPA;S:your ssid;P:your password;H:false;;" }` 34 | - `/status` return the connection status with format `{"status": "connected"}` 35 | - `/listap` list the reachable APs in format `{"accessPoints": [ { "ssid": "example", "strength": 54 } ]}` 36 | 37 | 38 | The connection string format is based on
