Hi folk, Just got my core recently & started digging - looks like fun. I’ve gone through a few of the basic ‘hello world’ tests & so far so good. What I would really want to do is have a customised mobile app control a custom build. I’m really not much of an Android dev (working on getting my Py…

Hi @kieppie - regarding your question about offline acess, we do intend to make it possible to work with the Spark Core without it being connected to the internet, but that feature is still in development. As for your request, it looks like you are sending a GET request, where the request you’re tr…

Expanding on zach’s reply: Try: curl "https://api.spark.io/v1/devices/$CORE_ID/digitalwrite -d access_token=$TOKEN -d params=D7,HIGH"

Thanks for the feedback, @zach & @BDub . @zach - looking forward to the non-net-connected release - seems a little silly to run potentially critical/vulnerable systems 'net-facing, especially outside of persistent wifi-range. @BDub - did find that info via API docco’s, worked OK from CLI, but was …

@kieppie What did your POST statement end up looking like? I just got my CORE and can’t get the POST request right in AI. Thanks

@jdmaharrey - I’m assuming you mean in the context of the MIT App inventor? I had to jump a few hoops - getting it to POST rather than GET was the trickiest part. The POST code/blocks looks looks something like this: [image] Overall it worked OK, but I had some weird disconnectivity issues whe…

kieppie would you mind posting the MIT project for downloading so I can see how you got it to post?

@kieppie I can’t seem to reproduce your result with my POST request. I would appreciate you pointing to some of the resources you used to get your result. Thanks

@chrisnet - I can’t see how to post/share App-inventor work. If you know how I’d be happy to. @jdmaharrey - honestly can’t recall where I found the info. I think managed to piece it together from scraps I found, some of which were form various google groups & other discussion fora & a lot of late-n…

OK - here you go MD5 checksum: 06ee75310879608ce866bb7031a05e1a Be sure to populate the textboxes with your device’s Device ID & Access Token. This is only my 1st attempt at this (I’m not an Android dev), so it’s a little rough around the edges - only supposed to be a PoC. To pull it in, see: Ca…

@kieppie Thanks to you I have my app controlling my core very reliably (I haven’t tried analog pins yet). I could not get the same code to work in App Inventor 1, but it works quite well in App Inventor 2.
