Changes in Mdtest V5 Compared To Previous V4

• Now can link WhatsApp using phone number pairing method.
  (Old V4) Previous method of scanning QR code was tiresome and needed a spare device.
  (New V5) Now with the new pairing method everything is done from the main device in a few seconds.
• Better support for sending images/videos/audio.
  (Old V4) Previously needed to send an image thumbnail seperately along with the main media file.
  (New V5) Now no longer necessary, Mdtest(V5) handles it.
• Added support for receiving media messages and downloading the media file.
  • Includes downloading images/videos/audio/documents/status/contacts/links/location previews.
    • To enable receiving media messages and downloading media in Tasker set variable %save_media = true
      The media files are stored in /data/data/net.dinglisch.android.taskerm/files/whatsmeow5/mdtest.7774/media (where 7774 = %port)
    • To enable receiving media messages and in Terminal(Termux) pass the --save-media flag when starting mdtest.
      The media files are stored in ~/whatsmeow5/mdtest/media
• Added support to send link preview messages.
  Only for websites that support the Open Graph protocol.

Instructions

For Tasker Users

Check the Tasker Reddit post for more info and importable Taskernet links.

For CLI Users

NOTE:-

This section is helpful for those who want to make shell scripts to use mdtest to send messages

Not recommended for Tasker beginners since there are ready made Taskernet links in the Tasker Reddit Post that you can import.

CLI In Tasker

Added preliminary CLI support to run mdtest from within Tasker itself using action [Run Shell].

1) Set it up as described in this Tasker Reddit post.

This will prepare Tasker to enable CLI support natively.

Your [Run Shell] action to use mdtest will look like this -

#!/system/bin/sh
mdtest_dir="/data/data/net.dinglisch.android.taskerm/files/whatsmeow5/mdtest"
cd $mdtest_dir/../mdtest.7774
sh $mdtest_dir/mdtest COMMAND PARAMETERS

CLI In Termux

CLI Setup:-

1) Install and open Termux in your device.

2) Grab the pre-compiled binary from releases or use the build script to compile it yourself in Termux.

Eg:- Depending on your device architecture(use uname -m to find out), you can download for arm,arm64(aarch64),x86 and x86_64 like this -

arch=arm64 && curl -L -o "mdtest-${arch}.zip" "https://github.com/HunterXProgrammer/Tasker-MdtestV5/releases/download/MdtestV5-Assets/mdtest-${arch}.zip" && mkdir -p ~/whatsmeow5/mdtest && unzip -o -d ~/whatsmeow5/mdtest mdtest-${arch}.zip && chmod -R 744 ~/whatsmeow5/mdtest/mdtest

OR

You can build and compile it by yourself in Termux -

rm -rf Tasker-MdtestV5 &>/dev/null
git clone https://github.com/HunterXProgrammer/Tasker-MdtestV5
cd Tasker-MdtestV5
bash build_whatsmeow5.sh
cd ..

3) After that link with WhatsApp like this -

Now to connect it to WhatsApp -

Type -

cd ~/whatsmeow5/mdtest; ./mdtest pair-phone 919876543210

(Here "91" is the country code and "9876543210" is the number. Adjust as needed)

This will generate the linking code.

You can copy the linking code and paste it in WhatsApp via notification

or by open WhatsApp -> ⋮ (menu) -> Linked Devices -> Link with phone number

Wait about 20s for pairing to complete. All done.

This finishes the CLI setup.

Your script will look like this -

#!/data/data/com.termux/files/usr/bin/bash
cd ~/whatsmeow5/mdtest
./mdtest FLAGS COMMAND PARAMETERS

Commands And Parameters

The FLAGS are -

--mode <value>
      Select mode: none, both or send
      (default option: none)
      - both -> Mdtest will receive mesages and as well as send messages
      - send -> Mdtest will only send messages, not receive.

--save-media
      Download And Save Media.
      - This flag also enables receiving media message types
        such as:- images, videos, audio, documents, contacts,
        status, location previews.
      - Media saved to ~/whatsmeow5/mdtest/media
      - Note:- To be used in conjuction with "--mode <value>"
               Will only be effective if "<value>" is "both"

--port <value>
      Port can be anything from 1024 ~ 65535
      It must not be 9990
      (default option: 7774)
      - Mdtest accepts requests on this port.
      - Note:-  To be used in conjuction with "--mode <value>"
                Will only accept requests if "<value>" is "both" or "send"

--auto-delete-media
      Delete Downloaded Media After 30s
      - Useful for auto-deleting rubbish media that probably won't
        ever be used.
      - The idea is that if the user doesn't use the
        downloaded media after 30s, save space by deleting
        what is most likely redundant files.
      - Note:- To be used in conjunction with "--save-media"

Note About JID

For single contacts, JID is usually the country-code followed by the phone-number and appended with "@s.whatsapp.net".
Eg:- Say country-code is "91", then JID will be ->
919876543210@s.whatsapp.net

For group contacts, JID is usually the group phone-number appended with "@g.us".
Eg:- 1234567890987654321@g.us
