Problem with Voice call sample app

vin883 · March 26, 2020, 5:38pm

jyijyi, it won’t work since the app does not lauch, so the “system(”/tmp/test.sh")" instruction won’t be completed!

My problem is that my app does not lauch. (until I do the “app start voiceCallService” in SSH console)

jyijyi · March 27, 2020, 12:06am

Didn’t here already say it is running?
Jan 6 00:05:52 | voiceCallApp[1429] | | sh:
Jan 6 00:05:52 | voiceCallApp[1429] | | app: not found
Jan 6 00:05:52 | voiceCallApp[1429] | |
You can run the shell script during startup to start the service.

3.Another method is that you rebuild the legato.cwe after you make the voicecallservice to run during start

Hi jyijyi,

Thanks again for helping me!

The main app only runs after manually starting the voiceCallService app in SSH console. I’d like the main app automatically lauch at power up.
and 3. Interesting, I will look after that and come back to you!

vin883 · March 27, 2020, 11:41am

It’s working!!!

I edited the .adef file in order to make the voicecallservice to run during start (Point 3 of last jyijyi post)

Thanks jyijyi you’re my hero

I also have a problem with the voiceCallApp when building the app.

github.com

legatoproject/legato-af/blob/master/apps/sample/voiceCallApp/voiceCallComponent/voiceCallApp.c

I cd’ed to the folder of the app and want to run the following command:

mkapp -t wp76xx voiceCallApp.adef

but then I get the following error regarding lines 289/290 of the voiceCallApp.c code

Does anyone know what I’m doing wrong?

tadera · September 4, 2020, 11:20am

I also tried this before:

mksys -t wp76xx voiceCallApp.sdef

as described here:

I’m afraid this throws the same error.

jyijyi · September 4, 2020, 11:37am

“-Werror=implicit-function-declaration” makes the problem.

Either you fix this in the code or you add “-Wno-error=implicit-function-declaration” flag during your compilation

tadera · September 4, 2020, 12:59pm

After adding

cflags:
{
-Wno-error=implicit-function-declaration
}

to the Component.cdef file this is what shows up next

I figure fixing the errors in the code might better than adding flags. It’s somewhat weird though as I’m working with a sample app and it throws errors anyway even though I didn’t change the code.

When I try to fix the error though like so

LE_ERROR(“Open file %s failure: errno.%d (%s)”,
AudioFilePath, errno, _ERRNO_H(errno)); // was LE_ERRNO_TXT before
DisconnectAllAudio(reference);

I get another error

The flag as described above is still implemented.

jyijyi · September 4, 2020, 1:11pm

Don’t change the code, add another flag “-Wno-error=format=”

tadera · September 4, 2020, 1:20pm

Don’t change as in leave it like this or leave it the way it originally was?

LE_ERROR(“Open file %s failure: errno.%d (%s)”,
AudioFilePath, errno, LE_ERRNO_TXT(errno));
DisconnectAllAudio(reference);

Because after adding the additional flag

cflags:
{
-Wno-error=implicit-function-declaration
-Wno-error=format=
}

it looks like I get a similar error

/home/mangoh/workspace/legato/apps/sample/voiceCallApp/voiceCallComponent/voiceCallApp.c:290:44: warning: implicit declaration of function ‘LE_ERRNO_TXT’; did you mean ‘_ERRNO_H’? [-Wimplicit-function-declaration]

I don’t see problem to compile in Developer Studio with WP76 R13 package.
You can use my application attached.
voiceCallTest.rar (343.2 KB)

tadera · September 7, 2020, 8:01am

As far as I can tell there is no audio file playback implemented as it’s the case in the voiceCallApp.
This is what I want to test since I can already place a call with a different script (mangOH/samples/tutorials/voice/mangohVoiceCall at master · mangOH/mangOH · GitHub).

jyijyi · September 7, 2020, 9:15am

I don’t see problem to compile the mangohVoiceCall app in Developer Studio with WP76 R13 package.

Not quite understand your situation, maybe you can directly attached your app here.

tadera · September 7, 2020, 10:22am

This is the app I’ve been trying to get running:

I’m afraid it’s too big to zip and upload here (the limit is 4mb) which is why I’m sharing the link with you.
The only changes I’ve made to this app is what you’ve suggested - adding new flags to Component.cdef like so

cflags:
{
    -Wno-error=implicit-function-declaration
    -Wno-error=format=
}

tadera · September 7, 2020, 12:30pm

So basically what I want to be able to do is call a cellphone using the mangOH Green and when the cellphone picks up I want the mangOH Green to play a .wavfile.

jyijyi · September 7, 2020, 12:54pm

have you tried with AT!AVAUDIO command?

BTW, I don’t see problem to compile the voiceCallApp app in Developer Studio with WP76 Legato 19.11.0 package.

tadera · September 7, 2020, 1:13pm

I’ve tried this How to do audio record and playback of VoLTE calls using WP7607 module - #5 by shatrughan - WP Series - Sierra Wireless Forum. There you described a similar approach.

ATCommands don’t seem to work for me.

On a side note, I talked to someone at Sierra Wireless the other day and they said that I shouldn’t develop in Developer Studio because it’s outdated.

jyijyi · September 7, 2020, 1:25pm

Then you can move to VSCode if you want. To me, the tool is the same for compilation.
BTW, you can also enter AT command in modem port in device manager. But I have no idea why it does not work for microcom…

tadera · September 8, 2020, 8:35am

It seems like AT commands weren’t enabled. After following these instructions https://linuxize.com/post/at-command-in-linux/ it can type in AT commands in Ubuntu’s terminal.

It looks like I can enter this:

root@swi-mdm9x28-wp:~# microcom /dev/ttyAT
ati3
OK
at!avcfg=5,1,2
OK
AT!AVSETPROFILE=5
OK

But after entering

AT!AVAUDIO=1,1,/home/mangOH/sample.wav

all it says is ERROR.

Do you know what the problem might be and is there a way to get a more detailed description of the error?

jyijyi · September 8, 2020, 8:38am

do you really have this file “/home/mangOH/sample.wav” on WP76 module?
It is strange that ati3 is returning nothing…
Why don’t you directly enter AT command on the modem port in Windows device manager?
