Board Usage without App and connection

italianfranny · July 2017

Hello,

I would like to use the board also without the App and the Bluetooth connection.

What I would like to do is this: when the button on the board is pressed the motor starts vibrating every minute, when the button is pressed again the vibration stops. I would like it to work without the app and the bluetooth connection. Would this work? Can you give me some suggestions for doing this?

Thank you very much!

Yes with reactions and data processing.

You can refer to this unit test for a starting point.

thank you very much Eric,

one more thing:

How can I detect a long press on the button?

I use this code to detect if the button is pressed or not:

source.count().map(Function2.MODULUS, 2)
        .multicast()
        .to().filter(Comparison.EQ, 1).react(new RouteComponent.Action() {}

	.to().filter(Comparison.EQ, 0).react(new RouteComponent.Action() {}

What do I have to add if I want to detect a long press?

Thanks again!

Dunno, never thought about detecting long presses before. What have you tried thus far?

I just need a way to stop the timer that manages the vibration. I was thinking of a long press on the button (I use a normal press to start the timer) but If you have a better idea I would appreciate your help! maybe a double tap?

Regarding the long press, can't we detect the the comparison is one for an amount of time/samples?

Eric · July 2017

You'll have to determine if that can be done, again, I have no idea and have not throught about detecting long press.

Why long press instead of your original idea of using the same button press to do different actions i.e. 1st = start, 2nd = stop, etc.

The original idea could work, but I had problems implementing it. Can you help me with that? The code I posted above finds the 1st press and when it is released. How can I detected the second press? thank you so much

Filter button release events from the data route.
