Anchor Alarm to Bluetooth Speaker

[Cariad1961]

I would really appreciate some help with getting Opencpn running on a Raspberry Pi (Raspbian OS) to output sound to a Bluetooth speaker.

I have successfully got my audio apps to play to the speaker by adding the following to the /etc/asound.conf :


# To redirect ALL output to speaker

pcm.!default {
type bluetooth
device 00:16:44:FD:6B:A0
profile "auto"

}

But blow me OpenCPN continues to send the sound to the 3.5mm jack !

Any help much appreciated.

does aplay output to bluetooth?


Another solution would be to use the anchor alarm in the watchdog plugin. It allows you to execute an arbitrary command, so you can pass the device to use as a command line parameter.

[Cariad1961]

Firstly thank you for getting back to me, and yes aplay outputs to the speaker without any additional commands.

The watchdog plugin is not compatible with the optimised ARM version of OpenCPN 3.2

Any other ideas will be most welcome.

Thank you.

[seandepagnier]

How is the watchdog plugin not compatible? Is it because you are using opencpn 3.2 instead of the latest beta?

[Cariad1961]

Hello, yes I am using 3.2, I tried the plugin with windows 3.2 and that did not work so I assumed it would not work with linux. I am not sure there is an optimised version for ARM machines of the latest Beta ?

I am very grateful for your feedback - my primary applicatoin of the project is as an anchor and AIS watch with low power consumption. I know I could use a wire to connect the two, but I have the nmea input coming in wireless and would like to do the same with the audio output.

[seandepagnier]

The version 3.2 is not optimized very well for arm processors, you should try the latest beta instead and if possible enable opengl acceleration by building glshim.

[Cariad1961]

Okay .... I am now on Version 4 on the Raspberry PI - still no sound with Bluetooth speaker.

I have tried installing watch dog with the command:

sudo dpkg -i watchdog_pi_1.1-1_armhf.deb

But I get the following error indicating I do not opencpn pacakage installed ( I compiled it on the Raspberry Pi.) :

~/opencpn/OpenCPN# sudo dpkg -i watchdog_pi_1.1-1_armhf.deb
(Reading database ... 82730 files and directories currently installed.)
Preparing to replace watchdog_pi 1.1 (using watchdog_pi_1.1-1_armhf.deb) ...
Unpacking replacement watchdog_pi ...
dpkg: dependency problems prevent configuration of watchdog_pi:
watchdog_pi depends on opencpn; however:
Package opencpn is not installed.

dpkg: error processing watchdog_pi (--install):
dependency problems - leaving unconfigured
Errors were encountered while processing:
watchdog_pi


I am no expert in Linux, but are you able to offer any tips on how to install watchdog from where I am ?

Any help appreciated

Paul

[Cariad1961]

Update: I have tried installing version 4.0 on windows xp box and installing Watchdog with no success i.e. plugin dll is in the plugin folder but there is no sign of the plugin when you go into options and try and enable it.

Similarly I have confirmed on the Raspbery pi the .so file is in:

/usr/lib/opencpn


It feels like I am missing something really obvious ?

Any help much appreciated.

Paul

2nd Edit:

Re installed windows OpenCPN 4 and Watchdog now working on windows .... just need to sort Raspberry Pi (Raspbian) any suggestions welcome.

Just wondering, any progress? I'm having problems running plug-ins in a home complied raspbian opencpm. Everything else, including the 2 build in plugins works fine.

Actually I installed OpenCPN from
http://agurney.com/raspi/opencpn_4.0.0-1_armhf_tides_map.deb

The plugin vdr was downloaded from OpenCPN site.
The systems stops with the following when I open the SetUp window.

[seandepagnier]

are the plugins in /usr/local/lib/opencpn? what files are there?

[deltasig]

In /usr/local/lib/opencpn I have libdashboard_pi.so, libgrib_pi.so and libvdr_pi.so. The last one being the one I downloaded (armhf) from the site.
It appears, though that the armhf versions are for arm7 units and not arm6 (like my RPi); and that causes the crash.
I'm looking for a way to compile the plugins I need locally in the RPi but I'm having trouble locating all the parts.

[seandepagnier]

yes, for armv6 you will need to compile from source.

deltasig...
If you have RPi-2 you could try my .deb linked here:
http://www.cruisersforum.com/forums/...ml#post1778787
or a later alpha version some posts above in the same thread.
