Got a Bluetooth (BT) dongle from SIAECOSYS in China. I have had issues connecting to the controller via PC COM/USB. It doesn’t always work, I have to repeatedly try until the controller and PC ‘gave-in’ (I’m sure it’s more complicated than that). However I have never had such issues with my ANT BMS which is BT enabled. So I think BT for the Kelly controller might make it easier to adjust the Motorcycle when needed.

Edit: … and on first try to connect, it synced with the controller seamlessly, only needed the 1234 password to pair… bloody amazing this BT technology eh, make it all so easy.
