Does BlueTooth work?

[jared]

See my post here. You’re asking about the same class of device just called a different name.

Bluetooth dont work with HC-05 (slave) and HC-06 (master/slave)

The issue is in the modality of communication that those devices use. I’m almost positive you can only transfer data via the broadcast channel. Thunkable apps do not have the internal infrastructure to receive and parse those messages at this time. For now, you must read from/write to the GATT characteristic service available on a BLE device. The ESP32 is perfect for this use case as. I have documented this in other threads.
