What kind of adapter, built-in or dongle? What does 'hciconfig -a' show? Have you tried 'sudo hciconfig hci0 reset'?

Hi all,
I don't want to start another thread on this subject.
My problem is that after a few days, the RPi3 bluetooth adapter is not detected anymore. I just did a totally fresh install with this Rasbian May-27-2016 image and booting directly with a HDMI monitor and the bluetooth icon is gray and says No Bluetooth adapter found.

Another problem is that I cannot find raspi-config.
Is raspi-config suppose to be in the menus somewhere? I don't see it now. I suspect that my Pi is dying
Apart from hciconfig, is there any other ways to check the bluetooth adapter presence?
Thanks for listening!

this is what I get in a terminal

Code: Select all

pi@raspberrypi:~ $ ps ax | grep blu
  990 ?        Ss     0:00 /usr/lib/bluetooth/bluetoothd
 2654 pts/0    S+     0:00 grep --color=auto blu
pi@raspberrypi:~ $ hciconfig -a
pi@raspberrypi:~ $

Hi,
Check for bluetooth.service,hciuart.service and bluetoothctl..Other than this use hcidump to know the actual problem.

Just checking you are running the update tools. Bluez seems to have been updated a few times along with some firmwares very recently.

Raspi-config should be in the menu in Raspian.

I did a fresh install.
apt-get upgrade shows :
"Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded."

1) deamon running but nothing in the bluetooth "sys"

Code: Select all

pi@raspberrypi:~ $ ps ax | grep blu
  461 ?        Ss     0:00 /usr/lib/bluetooth/bluetoothd
 2541 pts/3    S+     0:00 grep --color=auto blu
pi@raspberrypi:~ $ ls /sys/class/bluetooth
pi@raspberrypi:~ $ 

If I install a dongle, sys/class/bluetooth is populated.

2) where in the menu exactly should Raspi-config be? Menu-> xxx -> xxx ?

[jam1]

Should the bluetooth interface showed up when I do lshw or hwinfo?

I can see the wifi as wlan0 but no sign of bluetooth. Is it the same MAC address?

This is the last few lines from hwinfo

Menu -> Preferences -> Raspberry Pi Configuration for the GUI version

or type sudo raspi-config in a console window for the text version.



Also I'm assuming you run sudo apt-get update before sudo apt-get upgrade.

I know I recently created a new install (week back or so) and then there have been update.


I'm by no means an expert, just a beginner. Unfortunately have no real experience with debugging Bluetooth other than trying to turn the damn thing off on the Pi3 oh and attaching a WiiMote to it just to see.

You could also try sudo apt-get install pi-bluetooth to check it installed properly ?
(just something I had to do with an older raspian install to actually get it in the first place).

Good news today.
I did a fresh install again and the bluetooth controller magically appears.
I just hope it stays on from now on. I have no idea why it did not show up before.
