drinn

A simple server-client application that plays a bell when a specific messagge is received through a TCP connection.

Did this ever happen to you?

• You are listening to loud music on your headphones.
• Your mom is shouting at you from downstairs.
• She keeps shouting for 10 minutes.
• She comes upstairs. Angry.
• She pokes you and you realize you are in trouble.
• You are forced to keep an ear out in order to hear when she calls you.
• You are no longer able to enjoy music.

This is what would have happened if you had drinn:

• You are listening to loud music on your headphones.
• Your mom is shouting at you from downstairs.
• She notices you can't hear her and decides to use the drinn application on her phone.
• You hear the bell ringing in your headphones, you stop the music and respond to your mom.
• You get back to what you were listening. Happy.

Server setup (Windows)

Steps:

• Obtain the server executable (drinn.exe) by either downloading it from the release page or by building it yourself (use the build.bat file)
• Make sure that the files drinn.exe and drinn.mp3 are in the same directory
• Execute drinn.exe:
  • With the flag --set-volume <volume> you can change the volume at which the drinn is played
  • With the flag --no-adapters-info you disable the message displayed at the start of the program that lists all the network adapters and the relative IPs
  • With the flag --debug you enable additional debug messages
  • With the flag --set-autostart makes it so the program automatically start at system start-up, always using the same flags that were used along side this one
  • With the flag --help displays a help message explaining how to use the various flags
• Now you can wait for DRINNs to arrive

How to find the IP of my computer

It's important to know the IP of your computer in order to properly set up the Android application. There are multiple ways of finding it.

The easy one:

• Execute drinn.exe and look at the list of network adapters that is printed.
• If you are using the Wi-Fi then look for the adapter called something like "Wi-Fi" (the same goes for "Ethernet")

The difficult one:

• Deal with it yourself

Application setup (Android)

WHEN INSTALLING THE APP YOUR PHONE WILL PROBABLY WARN YOU AND ADVICE YOU NOT TO INSTALL THE APPLICATION, BECAUSE IT'S NOT SIGNED, SO THE PHONE DOESN'T KNOW WHERE IT COMES FROM AND DOESN'T LIKE IT. THIS WILL BE FIXED SOONER OR LATER, PROBABLY WHEN I'LL TRY TO LOAD THE APP IN THE PLAY STORE

Steps:

• Obtain the application installer (drinn.apk) by downloading it from the release page and install it.
• Open the app, you will be presented with a big button in the center and an input field on the top
• In the input field on the top you will need to insert the IP address of the computer on which the server is running (the one optained during the server setup)
• Now you can press the button, and hopefully a DRINN will be received on the other end
