Bluetooth packages look premature here.
Both kernel DTS copies only model the SDIO Wi‑Fi side of the RTL8821CS; I don't see any Bluetooth transport or serdev node under the enabled UARTs in
patch/kernel/archive/sunxi-6.18/dt_64/sun50i-h618-mellow-fly-c5.dtsLine 159-Line 169 and Line 273-Line 277, nor in the identical 6.19 copy. As-is, images will ship BlueZ packages even though the board support added here only describes Wi‑Fi.🤖 Prompt for AI Agents
