8. Wireless

Bluetooth, WLAN, and the radio-adjacent HAL layer: firmware/protocol internals, a two-bug audio-latency chain (one confirmed, one inferred), and the vendor driver/HAL bindings (including the present-but-disabled NFC/GNSS/FM/ANT+ HALs). WiFi and NFC are covered in Wireless drivers and HAL rather than a dedicated page.

• 8.1. Bluetooth / FM controller firmware (WCN3990 “Cherokee”)
• 8.2. Bluetooth A2DP sink-latency: a two-bug chain in the HAL path (one confirmed, one inferred)
