I have an iOT project. Where I need to send home wifi credentials on iOT device.

Firstly, I have to connect the mobile app to the iOT device hotspot. Then send wifi credentials to the iOT device without internet. then the device automatically connects to WiFi.

I already try lots of package but not been able to achieve this task.

I tried Following package wifi_iot flutter_iot_wifi flutter_esp_ble_prov esp_provisioning_ble esp_provisioning_softap

Can anyone tell me how I can achieve this?

1st method

  • Just create one local web server on the iOT device (ESP32) side.
  • Create one GET request on the local server (ex : /get_credantials).
  • Connect your smartphone to esp32 and send credentials via above GET request.

Example for reference: Link

2nd method

  • Create BLE Server on esp side and start advertising it
  • Create characteristic on same server with write/read access to get wifi credantials via BLE
  • Connect to that server via smartphone and send data through that characteristic.
