Are you using the ESP as bridge for an arduino or are you using it as a stand alone chip? For the second option it is possible to integrate OTA updates.

I'm using the ESP mostly with a static IP, but if not you can use e.g Network Scanner:

I have 3 different routers in my office and another router at home. so I was trying to find another way.

I did not exactly get that part. Where do I do the autoscan thing ?

Dave, I am using it as ESP-bridge connection. Giving it a static IP would be a good idea but how do I give it a static IP ? I will try the autoscanner thing.

Sorry, I'm only using the ESP as stand alone chip. I don't think there is an easy way to use static IP with the serial bridge. For more information you should have a look at the Github page: https://github.com/beckdac/ESP8266-transparent-bridge

Hey guys,

Could anyone tell me how to know the connection status ? Are there any AT commands for that ?
I am using the option 1.

Maybe this posting can help you, but only if your ESP use a static IP

Do you want to know the status from VoxCommando's point of view or from within your Arduino code?

What is voxcommando's point of view ?

I am using the option 1, so just burning the transparent bridge firmware. Not using any arduino code.

+++AT STA  should print the SSID (and password) of the router the ESP is connected to. Is that what you are looking for?
