WWDC CoreBluetooth Meetup
by Ramin Firoozye 03 Jun '13

Hi folks, Any interest in an informal CoreBluetooth Meetup during WWDC? Whether attending WWDC or not, let's get together for drinks and show-and-tell. If interested drop me a note at raminf(a)gmail.com (please don't spam the list) with which night works best for you and a brief description of what part of Bluetooth/CoreBluetooth you're most interested in. Thursday night is the bash and most people head out Friday afternoon, so the choices are Monday-Wednesday. Sunday June 9th perhaps around the time of http://sfmacindie.com is also an option. I'll see how many are interested and we'll try to find a nearby drinking spot and hang out. Extra bonus points to anyone bringing hardware to show off :-) Cheers, Ramin --- Ramin Firoozye Berkeley, CA --- _______________________________________________ Do not post admin requests to the list.

It may seem to make sense but at the same time UIImage aready does it for you, so it practically just makes things more complex without much gain. I haven't done testing as to how much caching CoreBluetooth does but I feel like this is something that is necessarily an OS function. On the other hand, people on this list have been complaining that it does actually cache quite aggressively, which hinders testing in some cases. All in all, implementing additional caching will surely make your code more complex (think of handling BT reset, crashes, hidden XPC errors, etc.) without much practical gain (if any). The difference here is that getting a UIImage is a synchronous operation, and everything in CB is async. It's actually a real pain to use the CB API if you want to represent the peripherals in Core Data and split interactions across controllers and Managed Object Contexts. If CB were a block-based API, a lot of my issues go away, but I'd still have to handle the async nature of things (which means keeping state around to make sure all of several characteristics have been discovered and then read). -- Rick _______________________________________________ Do not post admin requests to the list.

Re: YmsCoreBluetooth v0.94 update - now supporting OS X

Andras - Thanks for the feedback! FWIW, I didn't use subclasses nor categories because I could not think of an elegant way to deal with discovery and blocks at the same time. It seemed more obvious/comprehensible to me to use a container class pattern, especially when you know ahead of time what services, characteristics, and descriptors you are looking for. That said I'm open to insights on how to deal gracefully with discovery. Or maybe you'll agree with the path I took and give it a try. :) -Charles _______________________________________________ Do not post admin requests to the list. They will be ignored.

YmsCoreBluetooth v0.94 update - now supporting OS X
by Charles Y. Choi 03 Jun '13

03 Jun '13

Hi folks - Just a heads up about an update to an open source framework I wrote that puts a Block-based API on top of CoreBluetooth. Announcing the latest update to YmsCoreBluetooth, a framework for building Bluetooth 4.0 Low Energy (aka Smart or LE) iOS or OS X applications using the CoreBluetooth API. Includes Deanna and DeannaMac, applications to communicate with a TI SensorTag for iOS and OS X respectively. YmsCoreBluetooth features: * ObjectiveC Block-based API for Bluetooth LE communication. * Operations (e.g. scanning, retrieval, connection, reads, writes) map to the data object hierarchy of CoreBluetooth. <http://kickingvegas.github.io/YmsCoreBluetooth/> Have fun! -Charles _______________________________________________ Do not post admin requests to the list.
