How to Send Launch with Subscription

Parachain

Pay attention that this tutorial demonstrates using a subscription on Robonomics Kusama parachain. You can also perform all the same steps on your local node.

If your address has an active subscription, then any devices set up with that account’s secret can send extrinsics with no fee.
Let’s try to send the launch command.

Go to the Developer/Extrinsics page, then choose your account (the one from device list) and select rws -> call(subscriptionId, call).
Then in subscriptionId field paste the subscription’s owner address (the one who bid the auction) and in the next field
choose launch -> launch(robot, param). In the robot field type the address you want to send launch transaction
to and insert the command (for launch command description refer here). Then submit transaction:

Now go to the Network/Explorer page, and in the Recent Events area you will see two events that you created; rws.NewCall and launch.NewLaunch
