I am looking for an experienced Android Bluetooth engineer with **proven hands-on experience** with **Bluetooth LE Audio (LC3 Unicast)**.

## What I need

I need someone who can:

* Understand Android Bluetooth HAL, LE Audio architecture, BAP, PACS, ASCS, CIS, ISO and LC3.
* Determine whether the limitation is in Sony firmware, Android, OEM Bluetooth drivers or the application.
* Recommend or implement a solution.

* Bluetooth BAP
* Android Bluetooth stack
