Fixes an issue where newer Icomon boards (broadcasting as "AAA002") fail with an UNKNOWN_STATUS_CODE during GATT connection attempts. This commit bypasses the connection entirely and passively reads the BLE advertisement. - Added `IcomonBroadcastHandler` using LinkMode.BROADCAST_ONLY. - Implemented the 0xA0 XOR cipher to decrypt weight and impedance from the 0xA0AC manufacturer data payload. - Placed the new handler at the top of `ScaleFactory.kt` so it intercepts the AAA002 broadcast before the legacy GATT handler attempts to connect. Note: The protocol reverse-engineering and Kotlin implementation for this commit were developed with the assistance of generative AI.

Thanks for your PR but what about the already implemented AAAxHandler? Does it not work? I would prefer to fix that implementation. |

Hi @oliexdev, some days ago I opened the issue #1341 because when I try to pair the scale I see this I noticed later that a while ago a pr was done #1041, and if I understand correctly the measures should go, but they don't. So yes, probably there is some issue with the already implemented AAAxHandler (or maybe I'm missing something on how to use the app properly) |
