Hey Chris, the Firmata blink example linked at the Firmata guide doesn't seem to open on the iOS mworks app.

It is titled "firmata_blink.mwel". When I attempt to open it in the app using the "Choose experiment" dialogue, I receive a "No XML file found" error message. Can you advise?

    Hi Michael,

    You can't load MWEL files directly from the iOS app. You need to either load it via MWClient on a Mac, or convert it to XML first using /Library/Application Support/MWorks/MWEL/mwel2xml (again, on a Mac). I've done the latter and attached the resulting XML, which you should be able to load directly on your iPad. Be sure the insert the appropriate value for bluetooth_local_name before attempting to load it.
