How to wait and connect to a BlueTooth peripheral when it powers up ?

[MogaRaghu]

I have a requirement to connect to two Blue Tooth peripherals - one at a time - based on specific requirements.

The peripherals are simple HC05 / 06 modules connected to an Arduino each. 

The attached code does this function well - though i am not sure if this is the right way to do it ! ( This is just sample code only for the BT. Otherwise there are lot more functions to handle ) 

But i have a problem : For this to work it is essential that both the peripherals are powered before i start the VI. This is not how it will be in real time - both the peripherals are battery powered and i cannot afford to keep them powered indefenitley !! 

What i want to do is : Start the BlueTooth server on the VI and leave it running and link up when the peripheral comes on line. After all this is how all cell phones work - once the BT is enabled, it connects to any paired peripheral when it is powered.

Hmmm... I see that the outer loop is a stupid idea. Will remove it and work on a single loop with both BT instances inside that with selective calling and restarting when the Error node returns a fault. 

Maybe a shot of Scotch will help !!

Ok so the issue is resolved. 

The attached VI will do all what I planned to :

1. Selectively connect / disconnect to a BT Module that is sending data based on a FP switch.

2. If the User clicks Connect without powering up the module it tries to connect once every 5 seconds without throwing a fault.

3. If the BT module goes off line when connected, the code tries to auto reconnect once every 5 seconds. 

( The BT module was a HC05 driven by a Arduino Nano PCB sending millisecond data once every 100ms )
