Interact with AIRA
Important: Make sure you have covered previous lessons before you continue.
Tip: During the lesson you will type a few commands in terminal. AIRA image doesn't support clipboard, so to make life easier have a look at Connect via SSH and log in via SSH to the VM.
After you launched AIRA and logged in using your terminal do the following:
su liability && cd git clone https://github.com/vourhey/hello_aira cd hello_aira nix build -f release.nix source result/setup.bash rosrun hello_aira hello_aira
Run one by one commands above. After the last one you should see a link to DApp generated specifically for your instance.
Click on the link, the DApp should be shown.
Connect MetaMask if prompted and click on the button
Sign the message as usual and wait for the result
Meanwhile have a look at the terminal. You should see the greeting
In the end the greeting will appear in the DApp
You click "Request current values" but see no greeting
Probably you have just launched AIRA and IPFS hasn't finished initialization. Wait a minute or so and try again.
I see response hash but the data doesn't appear
Again most probably the issue comes from IPFS connection. Click and the hash and you'll see the result. It's not necessary to download the file.
