The peripheral hardware can send notification to iPhone every m seconds. iPhone in the central role can receive the notification in the background if app support corebluetooth background mode. 在 2013-6-29，上午3:00，bluetooth-dev-request@lists.apple.com 写道： > Send Bluetooth-dev mailing list submissions to > bluetooth-dev(a)lists.apple.com > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.apple.com/mailman/listinfo/bluetooth-dev > or, via email, send a message with subject or body 'help' to > bluetooth-dev-request(a)lists.apple.com > > You can reach the person managing the list at > bluetooth-dev-owner(a)lists.apple.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Bluetooth-dev digest..." > > > Today's Topics: > > 1. iPhone Tx power (Javaid, Bilal) > > > ---------------------------------------------------------------------- > > Message: 1 > Date: Fri, 28 Jun 2013 12:22:44 +0000 > From: "Javaid, Bilal" <BJavaid(a)hatci.com> > To: "bluetooth-dev(a)lists.apple.com" <bluetooth-dev(a)lists.apple.com> > Subject: iPhone Tx power > Message-ID: <04197A92DE00C847AAA32F2755304F9ADA96(a)aa-ex001.hatci.com> > Content-Type: text/plain; charset="iso-8859-1" > > Hello, > > I have the iPhone in the client role, and other Bluetooth hardware in the peripheral role. > > I was wondering if there is any way for the peripheral to know the Tx power of the iPhone in order to calculate path loss? > > I know I could just have the iPhone calculate path loss by putting the Tx power service in the external Bluetooth hardware, but the issue with that is that the phone can't continuously monitor path loss when the app is in the background because timers will not fire in the background. > > The alternative is to have the iPhone in peripheral role and that way I can capture Tx power in the phone's advertising packet, but I wanted to see if I could keep the current topology. > > Thanks, > Bilal Javaid >

Looking for Sample Code/Help with openRFCOMMChannelAsync:
by Janice McLaughlin 22 Jun '13

22 Jun '13

Hi all, I have some legacy code that I am incorporating into my application. It was originally written as a command line tool and I'm making it work in my NSWindow based application. It works once just fine and connects to the device and transfers data and then things get shut down. But I can't ever connect again to the same device in the same run of the application. The legacy code finished and never made another connection before exiting and so never had to worry about cleaning up properly and now I do. And I must not be doing it "right". The second time through, the call to: IOReturn ret = [_selectedDevice openRFCOMMChannelAsync:&_rfCommChannel withChannelID:1 delegate:self]; returns 0 for success, but the callback to: - (void)rfcommChannelOpenComplete:(IOBluetoothRFCOMMChannel *)channel status:(IOReturn)status; never happens the second time. FYI I have tried both doing a retain and not doing a retain on the returned _rfCommChannel and it doesn't appear to make a difference. (The documentation says it's not required but a search shows up that sample code does a retain). So I'm looking for the referenced sample code "RFCOMMClientSample" and/or "RFCOMM_Open_SPP_Example" to use as guidance for proper shutdown - both initiated from the Mac side and also when initiated from the device side, such that another connection can be made again later. I've looked in developer.apple.com and it's not there and of course there is no Developer/Examples/Bluetooth folder anymore to look in. Does anyone have this squirreled away that they could send me? Or point me to where it might be located? Or perhaps if you've run into this problem before, give me a push in the right direction as to what I'm doing wrong on cleanup? Thanks so much!

No, no auth required. OBEX auth is very unusual in mobile phones, or said differently, never met it. However, error codes are very wrong in implementations. Did you pick the right folder name? SetPath does not like / or \ or : in paths, actually, because some implementation do not like paths at all, I navigate to the root with SetPath. From there, I move each folder level with a seperate SetPath. Not sure whether Series 40 requires this, as well. I am abroad right now, and cannot test. One more thing: If you get a connection ID header from the result of a OBEX Connect, save that and supply it with every subsequent operation like SetPath and GET. This is a session you opened with the target header - much like cookies in HTTP. If that does not help, I am going to double-check when I am back at home. _______________________________________________ Do not post admin requests to the list. They will be ignored.

Matt, in background you only receive one advertisement packet per device.

I am periodically sending this data (on the order of once per 5 seconds) and was wondering if it is possible for the application to still receive this advertisement payload data when the the application moves to the background. I currently have been successful when the application is in the foreground but the application appears to only receive one advertisement in the background and then nothing else. > > Thanks for your help, > > -Matt > _______________________________________________ > Do not post admin requests to the list.
