[Bug] Failed to write characteristic

[shirish93]

Hi,

While trying to adjust the temperature or color of the mug, I get this error. I'm on MacOs, running Python 3.7. Can you guide me towards where I should look to debug it?

Changed Color to bytearray(b'\x18\x18\x18\xff')
.
Exception in callback PeripheralDelegate.did_write_value_for_characteristic(<CBPeripheral...e = connected>, <CBCharacteri...otifying = NO>, Error Domain=...ot permitted.})
