  1. For everyone that need a working Bluetooth on OPi3 i've found a fast solution: I'm using this version of Armbian: Linux orangepi3 5.3.1-sunxi64 #5.98.190930 SMP Mon Sep 30 02:43:17 CEST 2019 aarch64 GNU/Linux There is no need to use extra overlay or enable uart1, all the configurations are just present on sun50i-h6-orangepi-3.dtb. You can use the procedure indicated on previous post: and change the patching line to: /usr/bin/timeout 20s /usr/bin/brcm_patchram_plus --patchram /lib/firmware/brcm/BCM4345C5.hcd --no2bytes --bd_addr $MAC_OPTIONS /dev/$PORT 2>&1 Bluetooth must start without problem .... I've seen that a patch for bluetooth on OPi3 is just developed : https://lkml.org/lkml/2019/8/23/320 but i don't known if and when it will be included into mainline distribution.
  2. Yes as I said on the first post I use the scripts originally developed for C.H.I.P. board with the reset pin changed: The script use GPIO to generate a reset pulse on the line and it is necessary if you try to reconfigure the bluetooth module after each initial configuration.
  3. Probably you are missing the first one: CONFIG_SERIAL_DEV_BUS=m without this option the other two are ignored.
  4. If someone is interested I found the way to have BT working on orange pi Prime. Unfortunately default kernel config is missing the following options and need to be manually recompiled: CONFIG_SERIAL_DEV_BUS=m CONFIG_BT_HCIUART_SERDEV=y CONFIG_BT_HCIUART_3WIRE=y With these changes and adding "uart1" to the overlays in armbianEnv.txt it's possible to use the driver in: https://github.com/lwfinger/rtl8723bs_bt.git and start manually with: ./rtk_hciattach -n -s 115200 /dev/ttyS1 rtk_h5 to have bluetooth working. Alternatively it's possible to use a modified driver and some startup scripts originally developed by NextThings C.H.I.P. that i have modified to run on Orange pi Prime board. https://www.dropbox.com/s/swv2ylw6lnhljxk/rtl8723bs_bt.tar.gz?dl=0 What about to add these kernel options to default next sunxi64 kernel config ?
