[PROBLEM] Can't connect SPDIF/BT transmitter to moOde

[romain]

Suffice it to say that Bluetooth issues are difficult to troubleshoot.

Maybe once it's paired but before its connected try the command below to see if it shows something interesting.

Code:

bluealsa-aplay -l
bluealsa-aplay -L

pi@moode:~ $ bluealsa-aplay --help
Usage:
 bluealsa-aplay [OPTION]... [BT-ADDR]...

Options:
 -h, --help            print this help and exit
 -V, --version         print version and exit
 -v, --verbose         make output more verbose
 -l, --list-devices    list available BT audio devices
 -L, --list-pcms       list available BT audio PCMs
 -B, --dbus=NAME       BlueALSA service name suffix
 -D, --pcm=NAME        playback PCM device to use
 --pcm-buffer-time=INT playback PCM buffer time
 --pcm-period-time=INT playback PCM period time
 --profile-a2dp        use A2DP profile (default)
 --profile-sco         use SCO profile
 --single-audio        single audio mode

Note:
If one wants to receive audio from more than one Bluetooth device, it is
possible to specify more than one MAC address. By specifying any/empty MAC
address (00:00:00:00:00:00), one will allow connections from any Bluetooth
device. Without given explicit MAC address any/empty MAC is assumed.

Other thoughts:

- Try a different Class or Controller mode in /etc/bluetooth/main.conf.
- Try the btmon command
- Try a full manual pair/connect using bluetoothctl

Hello Tim,

I can pair and connect manually the CM150 with bluetoothctl and the btmon shows traffic between the transmitter and moOde BT however I can't hear anything :\
I've changed the BT CoD too in /etc/bluetooth/main.conf to 0x200408 (HiFi Audio Device), 0x200414 (Loudspeaker) and 0x200418 (Headphones) without success.

*BUT* if I connect my smartphone to moOde BT simultaneously to the CM150 I can hear the sound of my TV !?

Very odd.

You could also try the script that's used by the UI.

Code:

pi@moode:~ $ sudo /var/www/util/blu-control.sh --help
** blu-control.sh version 1.6
**
** Bluetooth has a range of around 30 feet (10 meters) but range
** will vary depending on obstacles (metal, wall, etc.), device signal
** strength and quality, and level of electromagnetic interferrence.
**
** Usage: blu-control.sh [OPTION]
**
** -i Initialize/reset controller
** -s Scan (BR/EDR only) and trust devices
** -S Scan (LE and BR/EDR) and trust devices
** -p List paired devices
** -c List connected devices
** -l List trusted 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 devices
** -h Help

I assume that you are trying to send audio from your TV to moOde. In that case verify that the Pairing Agent is on in the Bluetooth section of Renderers and that Audio output is set to "Local audio" in Bluetooth Control.

Hello,

here are the results of the tests I've made with the blu-control.sh script.

1. CM150 successfully pairs and connects according to the script (-p, -c and -l) but there's no sound from my moOde device and no BT overlay when I connect to moOde's web interface as if there were no BT source connected

2. If I connect another BT source, computer or smartphone, script output (-p, -c and -l) shows the CM150 and the other source, I can see the BT overlay with CM150 and the other device listed when I go to moOde's web interface and I can listen to the TV

3. If I disconnect the other BT source, sound stops and BT overlay disappears in moOde's interface whereas the CM150 is still connected according to the script

I hope my explanations are clear enough.

Thanks,
Romain

P.S. the CM150 is detected as UG-SPDIF-TX in moOde, I hope the dashes in the device name are not a problem
