After talking to @BOZHENG001, I think the problem is that Skald is implementing an older BLE version than BTHome expects and thus fields (such as TXAdd which is used as part of the nonce for encryption) are not in the place Home Assistant expects them to be. Will try to confirm this somehow. |

Contribution description
Little weekend (or rather Thursday and Friday night) project of mine. This extends Skald, who advertises to the world with BTHome, "an energy efficient but flexible BLE format for devices to broadcast their sensor data and button presses". The main use case is to integrate BLE-powered devices into Home Assistant.
Most of the spec is supported, except "Trigger based advertisements" (since Skald at the moment only advertises periodically). For encryption, I was able to confirm with the spec examples that at least from the generated output
is the expected one, given the example input, but Home Assistant is for some reason not able to decrypt the message (even the one in the examples)... So further investigation is needed.
TODOs:
Testing procedure
So far only tested by flashing a node and seeing the device pop-up in Home Assistant:
