Re: Disconnecting after enumeration

Rick, do you get more than one "didDiscoverServices" callback for a single discoverServices invocation? Would be new to me that this can happen.

I'm creating a little utility to examine devices, and I could use a timer to just disconnect after a moment of inactivity, but I thought I'd ask to see if there was a more definite way to determine all the services (for example) had been received. > > Thanks, > > -- > Rick > > > > _______________________________________________ > Do not post admin requests to the list.

Multiple bluetooth connections for RSSI

Thanks in advance! *SMC _______________________________________________ Do not post admin requests to the list. They will be ignored. Bluetooth-dev mailing list (Bluetooth-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: https://lists.apple.com/mailman/options/bluetooth-dev/site_archiver%40lists… This email sent to site_archiver(a)lists.apple.com I'm working on a bluetooth proximity application with a few Raspberry Pi's and some USB bluetooth dongles. The idea so far is that I've create a set of python scripts that will measure the signal strength via the "hcitool rssi aa:bb:cc:11:22:33" command to get the current RSSI value. If that value is of a strong enough strength, I mark that iPhone as "near" the proximity marker. My idea is to have a few of these around the house capable of "changing the way certain apps" behave. For instance, I'm using XBMC as my media center software and Logitech's Harmony Ultimate remotes and iPhone apps to control other home theater devices. I'd like to not have to switch rooms... so when the iPhone is in the living room and you up the XBMC Remote app, it will control the XBMC in the same room.... so as you walk from room to room, it will move the controls with you. This also can be used from a web page in my "automated home" portal to locate a phone. Very similar to the "Find my iPhone" app, except this one will actually tell you which room of the house its in! The problem I'm having is I can't seem to get very stable consistent connections. I've got one up and running with no problems at all... it gets RSSI values at a rate of almost 4 - 6 per second. Then I've got 2 more that I'm trying to add and I seem to be having tons of problems. It seems like a second and third device connect, stay connected and work for a while, but once I move from room to room, after a while the connects drop off and don't come back. Running an hcidump on the connection shows "access denied", "connection rejected", even "memory limit exceeded" and some "page timeout" errors also. Anyone have any idea on how I can track down what's wrong? Is this just me sitting the limit of what the iPhone 5 can track? Any ideas on how to "lighten" the load? Would spacing apart the checks work better? Is there a better way to check this? How about making a "baseband" connection vs the "rfcomm" connections that I'm using now?

CB*Manager restoration after reboot
by Andras Kovi 13 Oct '13

Does the manager restoration work after a reboot? iBeacons and ranging is restored after reboot but I wasn't able to replicate this for CB*Managers. _______________________________________________ Do not post admin requests to the list.

Re: Decoding iBeacon BLE message
by Stuart Smith 08 Oct '13

The last byte (0xC5) is not a fixed value. It is the 2's complement of 59. In the sample, the "measured power" of the iBeacon is -59dB. Yes, there's no service ID in the message. So [CBCentralManager scanForPeripheralsWithServices:options] in the background won't see the iBeacon, but this doesn't mean that the iPhone doesn't see it when backgrounded. iBeacons support is in CoreLocation; your app can express an interest in location changes when in the background. The flags field is explained in the Bluetooth spec (Core Spec, version 4.0, Volume 3 Part C (Generic Access Profile), section 18.1. hth, Stuart On 10/6/13 12:00 PM, "bluetooth-dev-request(a)lists.apple.com" <bluetooth-dev-request(a)lists.apple.com> wrote: >Message: 3 >Date: Sun, 06 Oct 2013 09:35:04 -0500 >From: Qinghui Tang <tangqinghui(a)hotmail.com> >To: Frederic Visticot <fvisticot(a)gmail.com>, > "bluetooth-dev(a)lists.apple.com" <bluetooth-dev(a)lists.apple.com> >Subject: RE: Decoding iBeacon BLE message >Message-ID: <SNT149-W872359A5B16CA0E3511DA1B6120(a)phx.gbl> >Content-Type: text/plain; charset="iso-8859-1" > > >the iBeacon is sent through manufacturer option in Advertisement packet. >http://stackoverflow.com/questions/18906988/what-is-the-ibeacon-bluetooth- >profile >1A Message Length (26 bytes), including 0xFF and all following >bytesFF Manufacturer option4C 00 Manufacturer ID (Apple's)02 15 > Apple specific, maybe defining the message type as "iBeacon" and it >length (0x15 = 21 bytes = 16+4+4+1) E2 C5 6D B5 DF FB 48 D2 B0 60 D0 F5 >A7 10 96 E0 (16bytes for UUID) >00 42 (2bytes for major) >00 58 (2bytes for minor) >C5 Seems fixed value > >From: fvisticot(a)gmail.com >Date: Sun, 6 Oct 2013 10:27:46 +0200 >Subject: Decoding iBeacon BLE message >To: bluetooth-dev(a)lists.apple.com > >I try to understand the BLE message send by an iBeacon (from Apple sample >app) >I have installed a BLE sniffer and I get the following message I have >tried to decode- Can someone help me to understand the remaining ? > >- In addition I do not see any serviceID send in the message: Does it >mean that the iBeacon can not be visible when the app is not in >foreground ? > >02 (length) > > > >01 (GAP_ADTYPE_FLAGS) > >1A ? > >1A Longueur (message length) > >FF 4C 00 02 15 ? > > > >E2 C5 6D B5 DF FB 48 D2 B0 60 D0 F5 A7 10 96 E0 (16bytes for UUID) > >00 42 (2bytes for major) > >00 58 (2bytes for minor) > >C5 (?) _______________________________________________ Do not post admin requests to the list.
