Beta support: MMS on chatty/mmsd on Modem Manager - help/testing wanted!

[kop316]

Thank for your work, i manage to get some results with Free Mobile (french mobile operator)



Two weird things...

The Provider's documentation say to use an APN (mmsfree) for MMS which is different from the one used for data (free) but mmsd give an error

Code:

mmsd[9491]: ModemManagerPlugin(): Setting Context...
mmsd[9491]: src/service.c:mms_service_set_mmsc() service 0x557ac86b90 mmsc http://mms.free.fr
mmsd[9491]: ModemManagerPlugin(): Max number of bearers: 1
mmsd[9491]: ModemManagerPlugin(): Current Context APN: free, mmsd settings MMS APN: mmsfree
mmsd[9491]: ModemManagerPlugin(): The modem is not connected to the correct APN!
mmsd[9491]: ModemManagerPlugin(): Set MMSC: http://mms.free.fr, Set Proxy: (null), Set MMS APN: mmsfree
mmsd[9491]: ModemManagerPlugin(): At Bearer Handler: path /org/freedesktop/ModemManager1/Modem/2 active 1 context_active 0
mmsd[9491]: ModemManagerPlugin(): Error activating context!

And mmsd do not succeed to resole CarrierMMSC=http://212.27.40.225

Code:

mmsd[11089]: src/service.c:process_request_queue() location (null)
request http://mms.free.fr
address (null)
port 80
host mms.free.fr
flags 0

bind failed: Invalid argument
connect_udp_channel failed!
mmsd[11089]: src/service.c:web_post_result_cb() Send </home/mobian/.mms/send.FZ8QX0.mms> complete

So at the end I try with this content into my ModemManagerSettings file

Code:

[Modem Manager]
CarrierMMSC=http://212.27.40.225
MMS_APN=free
CarrierMMSProxy=NULL

And it works...

For people who want to try a more complete howto for fresh Mobian install

Install ssh on your (if you prefer to use ssh from your computer)

Code:

sudo  apt install ssh

Once connected, install git clone all repo compile, and install.

Code:

sudo apt install git make build-essential build-dep
mkdir ~/src
cd ~/src
git clone https://source.puri.sm/kop316/purple-mm-sms.git
cd purple-mm-sms/
sudo apt install libebook-contacts1.2-dev
sudo apt install libpurple-dev libmm-glib-dev modemmanager
make
sudo make install
cd ~/src
git clone https://source.puri.sm/kop316/mmsd.git
cd mmsd
sudo apt install autotools-dev automake libtool
./bootstrap-configure --prefix=/usr/
make
sudo make install
cd ~/src
git clone https://source.puri.sm/Librem5/chatty.git
cd chatty
sudo apt -y build-dep .
meson build # or for debug mode: meson build -Db_sanitize=address -Dbuildtype=debug
ninja -C build
sudo ninja -C build install # if you want to replace regular install
sudo mv /etc/xdg/autostart/sm.puri.Chatty-daemon.desktop ~/ # or rm if you do not want to keep the file

To launch (or relaunch)

Code:

sudo killall mmsd
sudo killall chatty
~/src/mmsd/src/mmsd # or to debug: ~/src/mmsd/src/mmsd -n -d 'src/*'
~/src/chatty/build/run & # or to debug: G_MESSAGES_DEBUG=all ~/src/chatty/build/run --debug --verbose

Great! I am glad it works!

Thanks,
Looks like it is compiled and able to run. However when trying to run chatty via
G_MESSAGES_DEBUG=all chatty --debug --verbose
I receive a segmentation fault
(sm.puri.Chatty:1239): mm-sms-DEBUG: 11:34:57.681: got mmsd Manager

Segmentation fault

Nothing is returned / printed via the mmsd -n output.

Opps, had a typo with the apn configuration.

Now with the programs working mms fails to download.
I suspect this is because the download is being attempted directly without the mms proxy as there is a 404 error. It does appear to be using the correct ip / wwan0 connection.

APN settings:
[Modem Manager]
CarrierMMSC=http://aliasredirect.net/proxy/mmsc
MMS_APN=sp.telus.com
CarrierMMSProxy=74.49.0.18:80

Manually downloading using
curl --interface wwan0 --proxy 74.49.0.18:80 Download_URL_from_sms_in_mmsd_output -o test.mms;
recoverjpeg -b1 test.mms -o ./ -f test.jpg;
retrieved the test picture.

Hello!

The latest mmsd may have solved the Telus issue. Do you mind testing?
