Bluetooth mac address to variable

[Oregonerd]

Yes I’m new to App inventor.
I’m trying to make a spiffy Bluetooth connect/disconnect button with auto reconnect to last connected device to my Arduino.

my app is based on 2 of Z-hut’s tutorials. I’m trying to store the mac address from the list picker into a variable to user later.
I reports “true”.

I saw a thread that suggested looking at a bluetooth chat the displayed "trying to connect to: (mac adress). It used a “Call print textToPrint” procedure? I cannot find that in App inventor.

A nudge in the right direction would be appreciated. And I hope to share it with will all should it work as planned. Is there a place to do that? Thanks.

this looks like a custom procedure...

if you can provide a link to that thread then someone can probably say more...

It was from your recommendation that I found the chat app http://puravidaapps.com/btchat.php. I downloaded it and looked it over. I put it in the backpack but it wouldn’t work in my app red (X)

How can I check if a Bluetooth device is still paired?

this [unknown] returns true or false, in your case true then you assign that value to Listpicler.Selection ant therefore it is true in the end usually you use an if statement like this if BluetoothClient.Connected.. then "connected" else "not connected" the question is, what do you get back from Listpicker.Selection without assigning another value? And this then will be the selected combination of mac address and device name... just split Listpicker.Selection by space (you can find …
