4.2 bluetooth
#1
Congratulations on releasing v4.2! I like the UI changes and the improvements to squeezelite integration. But I'm having a bit of trouble with making bluetooth behave. I got it working in v4.1 by modifying a config file to load the A2DP protocol and once I had my Android phone paired it worked great, I could switch bluetooth on on my phone and media audio would play to Moode.
On v4.2 it was much, much easier to get the phone connected but since doing so it hasn't been at all as smooth. When I switch on bluetooth on my phone media still plays out of the phone, and even pressing the Moode Bluetooth entry in the bluetooth settings screen doesn't transfer it to Moode. I have to use the Moode menu to connect. I'm not sure if this is a bug or a deliberate change, but I preferred the old behaviour. Is it possible to alter the behaviour so that a previously paired device can auto-connect to Moode, either through the UI or through editing a config file somewhere?

Thanks!

Hi,

Bluetooth auto-connect is working fine on my end with IOS devices and an Anker Speaker. I don't have any Android devices to use for testing so I'm not going to be able to do any hands on.

Which client created the initial pairing, moOde or your Android device?

The label "Android phone" isn't very definitive. What make and model, what version of Android?

I have a Nexus 6P phone running Android 8.1.0 and Nexus 7 and 9 tablets running Android 6.0.1 and 7.1.1 respectively. I just installed moOde 4.2 on an RPi3B+.

Once I've gone through the initial pairing and connecting process with each Android device, I can switch back and forth between normal moOde mode and the Bluetooth sink mode (moOde plays audio from the BT connection) easily with the Nexus 9 and the Nexus 6P devices simply by connecting/disconnecting via the their Bluetooth menu or by switching off their Bluetooth controller. It's a bit more fiddly with the Nexus 7 but it still works without recourse to the moOde Bluetooth configuration screen.

In summary, I don't see the behavior you report.

Regards,
Kent

I paired from the phone to Moode. The behaviour is the same on my OnePlus 3 (OxygenOs 5.0.3 based on Android 8.0.0) and my wife's Samsung Galaxy S7 (Android 6.0.1), though the Samsung is slightly more verbose in that it gives an error message if I try to connect from the phone to Moode ("Unable to connect to Moode Bluetooth") whereas the OnePlus just fails silently. If I connect from the BlueZ config screen on Moode it works every time, to either phone. My Moode is a Raspberry Pi 2B with a USB bluetooth 4.2 dongle.

If there are any logs I can send that would help, I'll be happy to.

Very odd.

If you know some Linux ssh then you can run the bt.sh command script manually to see if it reports something useful.

ssh pi@moode (pwd=moodeaudio)
sudo /var/www/command/bt.sh <arg>

Example that prints the list of command args

sudo pi@rp3:~ $ sudo /var/www/command/bt.sh
** BlueMoode version 1.5
**
** Usage: bt.sh [OPTION]
** -i initialize/reset controller
** -s scan and trust devices
** -l list discovered devices
** -p list paired devices
** -c list connected devices
** -d disconnect device <MAC addr>
** -r remove paired device <MAC addr>
** -P pair with device <MAC addr>
** -C connect to device <MAC addr>
** -D disconnect all devices
** -R remove all pairings
** -h help
pi@rp3:~ $

There is also the btmon utility and the bluetoothctl util.

I've run btmon.sh and it appears to produce the expected output - both the Samsung Galaxy and Rohan (my OnePlus) paired, but not connected. I ran btmon and then attempted to connect from the OnePlus: the output contains an error message about permissions, see below.

Code:
pi@moode:~ $ sudo /var/www/command/bt.sh -l

I ran btmon and then attempted to connect from the OnePlus: the output contains an error message about permissions, see below.
...

So that
Code:
= bluetoothd: Authentication attempt without agent

means the Bluez package doesn't trust your OnePlus. What do you see if you run bt.sh with the -s option?
Here's an example from my moOde installation:

Code:
pi@moode-42b3p:/var/log $ sudo /var/www/command/bt.sh -s
** Scanning for devices (20 secs)
**
** Trusted devices
** 5C:F3:70:89:11:49 T520
** FC:3F:7C:9A:D8:AF Nexus 6P
** D4:0B:1A:19:6D:C0 Nexus 9
**
** Scan complete

All my devices (T520 is my Linux laptop; not another Android device) are trusted and I can pair and connect from any of them. [1]
I don't know why your OnePlus ends up untrusted. You could try to force the trust relationship using the command-line tool bluetoothctl.
What do the command-line tools report when you try to connect from the Samsung Galaxy? is it similarly untrusted?

Regards,
Kent

[1] while horsing around with all my Nexus devices I managed to get into a state similar to what you report. All of the devices were paired, all had previously connected, but at some point I couldn't (re)connect from one. I was able to get back to a working connection by clearing the previous data and going through the pairing/connection process again. Sadly, I didn't use any of the command-line tools to gather information before I did so.

That was very odd: bt.sh said that both devices were trusted. However I tried forcing them to trusted using bluetoothctl as you suggested, and now they both work perfectly. Thanks for the tip!

Maybe it would be worth including the ability to force-trust devices through the GUI, maybe even automatically just for belt and braces, into a future update?

Thanks Kent!

Can someone give me a detailed explanation of how to use the command-line tool bluetoothctl  in order force moode to trust my samsung s-7 as a bluetooth device

thanks

Connect to the moode system using SSH or a local keyboard/screen.
Find the MAC address of you phone's bluetooth.
enter "bluetoothctl", might need "sudo"
enter "trust "my MAC address" substituting your phone's MAC address.
