Bluetooth (RTL8723D USB combo chip): - GPIO pin 357 (active low) enables WiFi/BT hardware via x6200_gpio_set() - bluez5_utils 5.64 (downgraded from 5.79 — HID input plugin broken in 5.79) - rtl8723d_config.bin added to overlay (missing from linux-firmware package) - S45wifi-bt: GPIO enable + modprobe btusb/uhid/hidp at boot - S85bt-keyboard: auto-connect loop with scan+connect every 20s WiFi (RTL8723DU): - out-of-tree lwfinger/rtw88 driver (RTW88_8723DU not in kernel 6.1 mainline) - linux-firmware RTL_RTW88 for rtw88/rtw8723d_fw.bin - regulatory.db for cfg80211 - wpa_supplicant with multi-network config in /etc/wpa_supplicant.conf - S46wifi: wpa_supplicant + udhcpc at boot Key findings: - RTL8723D USB WiFi (0bda:d723) requires out-of-tree rtw88 on kernel 6.1 - BT and WiFi share same USB device, both need GPIO 357 = 0 to power on - bluez5 5.79 HID input plugin not linked into bluetoothd (build system bug)
