No worries. You're not alone with this, it's like every couple of days there's somebody heading off on a BLE safari on this forum. Erel's BLE2 example is great, but I get the feeling it's also a bit comprehensive and maybe intimidating for people who are also coming to grips with B4A at the same time. So I've tried to simplify things, and the only assumption I think remains is that you know to save the new project into a blank directory and let B4A create its own directory structure under that.
If there is anything about those instructions that makes things harder rather than easier, let me know (I promise not to take it personally ;-) and if I ever get around to tidying up the mess, I'll factor all suggestions in then.
Now... don't let me distract you here, get back into that jungle
