Paul, You might want to check the Apple Bluetooth Guidelines and make sure your device follows them. https://developer.apple.com/hardwaredrivers/BluetoothDesignGuidelines.pdf Thanks, Joakim On Jun 25, 2012, at 2:52 PM, Paul Stuart <paul_stuart(a)seektech.com> wrote: > Hello, > We are part of the MFI program working on a linux-based imaging accessory.

Re: Expose the Service and Characteristic and Central role in iOS6
by Daisuke Matsuoh 25 Jun '12

25 Jun '12

Hi Daisuke, You might want to check out the "Advanced Core Bluetooth" presentation from WWDC earlier this month. We have taken the approach that two modes are supported. 1. Central and Client 2. Peripheral and Server However, the GATT Server in the iPhone is accessible from the Peripheral so it should be possible to do the other permutations as well. Please give it a try and let me know if there are any issues. Thanks, Joakim On Jun 21, 2012, at 8:52 PM, mailto:matsuohd@citizen.co.jp wrote: Hi, I've read the “Bluetooth Accessory Design Guidelines for iOS 6” and let me confirm these things in the document, please. Can a Central object access/monitor the data on GATT server in iOS device itself? Could we implement Central role as GATT server? Thanks for your cooperation.

The other device is scanning for advertising packets from peripherals. Once it sees an advertising packet with an RSSI (Received Signal Strength Indication) higher than -30 dB, it connects to the device and gets the info (vCard). You can pick any RSSI trigger level you want for your application. Core Bluetooth simply gives you the advertising packet and at what RSSI it was received. It's then up to the app to decide if its close enough to connect. > > Once connected, they can stay connected for up to about 50ft (very much dependent on the environment however). Advertising packets can usually be detected further away. Give it a try and see if it works for your app. I watched the WWDC video, and I was surprised that the application used Notifications vs. Indications to transfer the chunks of the vCard between the peripheral and central devices. I would have expected that using Indications might provide some flow-control as well as more reliable transport between the two device. Or perhaps I was taking the narrative too literally?
