[SOLVED] Cannot enable Bluetooth

[R2ots]

Hello,

First of all thank you for this software, which is really great !

Since a Moode update a few months ago (I cannot remember which version I was running at this time), I cannot use Bluetooth anymore. It is set to ON in the System Config, but everytime I try to put it ON in the Audio Settings the system startup fails.

Then I need to install a fresh image, or to run the SQL command below via SSH to deactivate Bluetooth:

Code:

sqlite3 /var/local/www/db/moode-sqlite3.db "update cfg_system set value='0' where param='btsvc'"

I am now running Moode 6.5.2 on a RPI 3b with the x20 HiFi Audio Kit (http://www.suptronics.com/miniPCkits/x20.html).

Am I missing something ? Maybe my integrated Bluetooth adapter stopped working correctly ?

Many thanks in advance for your help.

This problem sneaked up on us. It was mentioned just the other day and I'm doing some testing for Tim as I write this. Stay tuned.

I think this a different issue. Prolly the metal case for the Suptronics is killing wireless.

[R2ots]

Thank you for your answers. However the metal case only contains the power supply, so I guess it has no effect on the wireless ?

You could try reboot then look at syslog for bluetooth errors.

Here's what my Pi-4B reports

The "cat /var/log/syslog | grep -i blue" command does not return anything on my system.

However I noted power supply issues in the regular syslog. Do you think it can be the root cause of my Bluetooth issues ?

Code:

May 23 17:04:21 moode kernel: [  354.785588] Under-voltage detected! (0x00050005)                                                          
May 23 17:04:25 moode kernel: [  358.817536] Voltage normalised (0x00000000)                                                                

Thank you.

Open System Config and verify that the Bluetooth adapter is ON.

Also check /boot/config.txt and verify that the Bluetooth adapter is not disabled. It should look like below where the wifi and bt lines are commented out (#).

pi@rp2:~ $ cat /boot/config.txt
disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=off
framebuffer_width=800
framebuffer_height=444
framebuffer_aspect=-1
dtoverlay=allo-boss-dac-pcm512x-audio
#dtoverlay=pi3-disable-wifi
#dtoverlay=pi3-disable-bt

OK I found out what was wrong.

Bluetooth adapter was ON in System Config, but WiFi adapter was OFF. So I switched WiFi adapter back to ON and activated Bluetooth in Audio Config, and then it worked !

So I guess that you cannot deactivate WiFi without deactivating Bluetooth, at least on this Pi model.

Thank you for your help !
