How to check Bluetooth Connection

[Wojciech Borkowski]

Hello guys,

I already can connect and disconnect to my BT module (HC-06), but I don't know how to check the connection. I want to alert user about no power on arduino with this module, how can I make this? I spend few hours thinking about it and there is nothing here, please help.

I attach my block diagram.

send some text to the Arduino and if your get a response, you know it is still connected, else it is disconnected

btw. you might want to connect correctly like this...

@Taifun - thank you for your answer

I modified block diagram and now it looks like this. I used your suggestion about correctly connection. I noticed, that error 516 is about broken pipe, so I used it for disconnect my BT, please tell my is that right thing.

the property IsConnected will not be updated automatically in case the connection is gone

to check if the devices are still connected, as far as I know there is only the already mentioned method...

send some text to the Arduino and if your get a response, you know it is still connected, else it is disconnected

Yeap, tried to use "IsConnected" but it isn't work. You might not notice that I add sending "t" to timer1 :)
