  1. 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.
  2. Probably you are missing the first one: CONFIG_SERIAL_DEV_BUS=m without this option the other two are ignored.
  3. 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 ?
