Problem with killing process in Android

[TheRaven]

Hello !

I've created an app based on the nrf blinky master : it works perfectly on my smartphones. But when I kill the app, and when I relaunch it, it doesn't connect (or it connects, but in 2 minutes at least)

Do you know why, please ? I've been searching for five days, but I couldn't fix the problem.

I wonder that it it due to the GATT, which has to be reinitialized ?

Hmm.. so you get the onConnectionStateChanged callback delayed? That's very weird. I'd have to see the code.

I add a Log.d in the onConnectionStateChange : it is executed immediatly after the connection on the board. It seems the problem is that a flag that I use to detect the connection was missing it onConnectionStateChange. I will confirm this quickly after testing it with the board !

Hello ! I still have a problem : when I re-open the app, the phone connects immediatly to the board, but onConnectionStateChange doesn't change. Where can I see the function launched during this connection in order to update my connection flag, please ?

[Aleksander Nowakowski]

I don't understand. Do you call connectGatt when you launch the app? And you don't get callback immediately after the connection was done? It's something very wrong.
