How I can get data from Bluetooth device to Simulink in a loop

Hello, I have problems with the DataStream function (watch pictures below). If i start the simulation the Init function works and the bluetooth object was created. But simulink can not find the variable b. Thanks for any ideas.

This is because "b" is not in the scope of "DataStream" function. You will need to pass "b" as an input to "DataStream" function or define "b" Bluetooth object, inside "DataStream" function.

Hi, I have the same problem with the difference that:

Only I use a function to send messages via Bluetooth.

It tells me that however the Bluetooth-type variable is not supported!

I have the same problem. I am not able to define a bluetooth object in Simulink. Anyone can help? Thank you.
