I’m testing thunkable with Silicon Labs modules implementing the Bluetooth Xpress service, which is an UART over BLE data streaming.  
Such modules require encription pairing, while bonding is an option.

I can easily scan, connect and disconnect without getting any error.  
The peripheral module is actually connected, it is not visible to other central, but the connected module does not switch from COMMAND to STREAM when connected and back to COMMAND mode when disconnected and actually I do not get any system pop-up asking for device association, which is a bit weird. So I guess that pairing was not implemented so far. Is that correct?  
Is there any way to implement the pairing? Any “beta” extension module?
