WIFI: Pass & User //No touching the firmware

[Nasib Fahim]

Hi all. I am using the esp32s2 device. I have programed a staion with some sensors that connects to wifi and sends some data to my server.

I guess this is a typical question but i didnt find a clear answer:

How can i introduce the wifi pass and user with out declaring them in the code ? I mean, is there any way to connect my device to any wifi with out modifying the firmware?

Thanks a lot in advance for your help!

Best regards.

Hi felmune. Thanks for your response. Normally are IoT comertial devices use BLE to pass the credentials to the device? There is not an easier way ass a AP button in the router or something like that ? I have never use a IoT device from the market.. so i dont know the stadard used here..

Thanks..

Hello @Nasib Fahim

there are many ways to get a device connected to WiFi. As far as I understand provisioning manager supports BLE and WiFi. But I guess you are looking for something like WPS.

Check out this example https://github.com/espressif/esp-idf/tr ... s/wifi/wps

Thanks

Also see the Espressif site discussion of this topic: Wi-Fi Provisioning. There are other options besides BLE. For example, you can use a configuration page implemented with Soft AP, or use Smartconfig.
