Receiving SSID/Password from Mobile App via UDP

Hi,

I need to use a Mobile App to send SSID/Password to Esp. I can do it two ways - one using Wifimanager library and second by using Espressif's smartconfig but the ESP's Smartconfig is very unreliable in my limited experience with it and hence, I would like to explore another way.

Would it be possible for this task to be accomplished via UDP broadcast from mobile app without Esp connecting to any local wifi? If yes, can anyone guide me to a resource on this or any hints which can help me?

Thanks!

ESP may be set up as an access point which basically means that it functions as a wifi router to which you can connect with a smart phone.

If you need to be able to wirelessly tell the ESP which network (SSID + PWD) to connect to, you might want to use bluetooth for that, though..

I have read that the ESP's smartconfig works on UDP's monitor mode. Is that something that can be easy to work with or is it too much work?

I have not used ESP's SmartConfig, but it looks like it is pretty simple to implement.
