Odroid XU4 - Bluetooth inactive after reboot and fan always off?

Hi :slight_smile:

I cannot succeed to keep the bluetooth active after a reboot… even with the nano .config/udev.rules.d/bluetooth.rules

with this content :

Set bluetooth power up

ACTION==“add”, KERNEL==“hci0”, RUN+="/usr/bin/hciconfig hci0 up"

I always have to type “systemctl start bluetooth” …

My other problem is the fan of the XU4. The radiator seems to be very hot (after few minutes after power on) but the fan is always off ? Is it normal ?

Both issues tested with latest stable then latest nightly.

Any ideas ?

Thanks :slight_smile:

I have solved the fan problem. After checking, it appears that one of the fan’s wire was desoldered ! It works again now.

However, I still have the bluetooth problem after a reboot… still no ideas ? :frowning:

Finally found a solution for the “bluetooth inactive after reboot” problem !

Here’s the solution in 4 steps :

  1. Enable the autostart.sh file
systemctl enable retroarch-autostart.service
  1. Create & open the autostart.sh file
nano /storage/.config/autostart.sh
  1. Fill the file with this content

(
 systemctl start bluetooth
) &
  1. Restart the Odroid
shutdown -r now

And voilĂ  :slight_smile:

The bluetooth service should now start automatically after reboots :slight_smile:
