Use the image below to understand if your rooftop unit has a brushless or brushed fan. If it has a brushed fan, then it is not bluetooth compatible.
So if yours looks like in the photo then it does not support bluetooth.
If the plug is on the other side, described Brushless fan below, then it is bluetooth compatible.
There is a very limited amount of units out that have a brushless fan, without bluetooth compatibility, which could be upgraded to a bluetooth panel.
Underbench AC units do not support Bluetooth compatibility.
Below is a photo of a Control Panel that has the Bluetooth Chip.
