John - Thanks for the suggestion of OCMock. I'm wondering however, if I want to test actual BLE communication, will OCMock help here? -Charles On May 6, 2013, at 10:24 PM, John Earl <jearl(a)airsource.co.uk> wrote: > Havent looked at your project, but OCMock works great for unit testing > Core Bluetooth code, would recommend it. _______________________________________________ Do not post admin requests to the list.

Are you by any chance planning to attend altWWDC? <http://altwwdc-eanrecfeatb.eventbrite.com/?ref=eanrec&utm_source=eb_email&u…> (I tried, but couldn't get a ticket to WWDC this year.) I'd love to meet up and chat about what you're doing with the TI sensor tag. And I might be able to help out with the testing. (I have three of them so far.) On May 6, 2013, at 5:37 PM, "Charles Y.

Havent looked at your project, but OCMock works great for unit testing Core Bluetooth code, would recommend it. On 7 May 2013, at 01:37, "Charles Y.

Hello and sharing my CoreBluetooth code
by Charles Y. Choi 07 May '13

Hello! I'm new to the list and look forward to future discussion. I've been working with CoreBluetooth to talk to a TI SensorTag and have published my results on GitHub. http://kickingvegas.github.io/YmsCoreBluetooth/ I'd be happy to hear feedback from this group and ways to improve the code. In particular I'm trying to figure out how to unit test CoreBluetooth and would appreciate input on how to go about testing async peripheral calls.

Help understanding gatt.service_changed
by Rick Mann 06 May '13

06 May '13

Looking at the spec, it has multiple value fields: http://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicVie… I don't know how to interpret that. As far as I can tell, a characteristic has a single value. How do I properly notify that a service has changed?

Re: Connecting to a CC2540 from the Xcode simulator
by Rick Mann 04 May '13

Be sure to stop scanning before you attempt to connect. I found that although it worked on iPad 3, it did not work in the simulator unless I stopped scanning first. Actually, it did connect, but took a very, very long time.

I've now tested the my code and device on actual hardware and on the simulator. Here are my results: iOS 6 Simulator: Doesn't connect iOS5 Simulator: Connects iOS5 Device: Connects iOS6 Device: Connects So the problem seems to be isolated to the iOS 6 simulator.
