Error handling for puck.js communication

Hi,

I am trying to add puckjs support for the Open Source AsTeRICS Grid AAC software in order to have an IR device or to remote controll battery-powerd toys using the FET output (see PR#340).

Is there a way to handle bluetooth disconnect or write error when using Puck.writefunction?
I would like to notify the user in such a case and maybe trigger a reconnect.

I also tried to use Puck.connect(), but this always forces me to reconnect to the device. If there was a previous successful connection, I would like to reuse it, not having to ask the user again.

Thanks for you help.

You mean using the Puck.js library? (source at https://github.com/espruino/EspruinoWebT­ools/blob/master/puck.js)

I believe you can use Puck. /getConnection() to get the currently active connection (you can use Puck.connect if not) and then you can do connection.on('close', function(d) { ... }) on that?

Hi Gordon,

Thanks for the hint, we have finally managed it by doing some modifications in our fork:
https://github.com/asterics/EspruinoWebT­ools

Your Espruino devices and the fact that you can easily program then via Web Bluetooth and Javascript are really awesome. This enables also a lot of possibilities for people with disabilities in combination with our AAC software AsTeRICS Grid.
We have added a UART action which allows to communicate with your devices and enable interfacing accessible toys or using the puckmote webpage and the IR-database to do environmental control for people with disabilities:

We will also use new feature this week in a series of workshops in Nairobi in Kenia.
I would be happy, if you could share the AsTeRICS Grid integration also in your platforms.

Thanks
Martin

Hi,

That's great! It's really good to see it used for this kind of thing.

It looks like the changes in your fork aren't something I could pull back as they delete a bunch of stuff and change the API, but if you did want to contribute something back that added connectBluetooth/etc without changing the rest then I'd be happy to pull that in.

Hi,

Oh, I was primarily thinking of adding a tutorial about accessibility use cases to the puck-js documentation.
Here are 2 documented tutorials:

It's up to you!
