+1 for being able to get access to that source code. Would be great.

WWDC Session 705 Demo Code
by Jeffrey Niblack 27 Jun '12

27 Jun '12

During the 705 session at WWDC (Advanced Core Bluetooth), Khrob Edmonds showed an app (LeCard). Is there a way to get that source code? For the other Core Bluetooth session, the source code for the heart rate monitor app was provided. Thanks, Jeff _______________________________________________ Do not post admin requests to the list.

get RSSI from notification
by 163 27 Jun '12

27 Jun '12

Hi, I schedule a Timer to read RSSI using readRSSI function ,but the timer stops when my app go into background. Maybe there is a good method to get RSSI value from peripheral's notification when app comes into background . But I don't know how to do. Could anybody help me? Anyone has a better method?

Keeping that VCard app in mind: The 'real life' example would be, that 2 users just open the app and THEN they decide who sends and who receives (or, if one user presses 'Send', it's app switches to server mode and the other user's app automagically switches to client mode)?

Re: Cannot find BLE peripheral when scanning for specific services
by Craig Dooley 26 Jun '12

Hi Ben, scanForPeripheralsWithServices: applies a filter to the scan response. In other words, your device must advertise this service in it's advertising data to be passed back to the application. We do not connect to each device and perform service discovery. Passing nil in allows all devices to be sent to the app. - Craig On Jun 26, 2012, at 2:26 PM, "Mosher, Ben" <Ben.Mosher(a)ncr.com> wrote: > When I use: > > CBUUID * uuid = [CBUUID UUIDWithString:@"1800"]; // GAP > DEBUG_LOG(@"CBUUID: %@",uuid); // CBUUID: Generic Access Profile > _centralMan = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; > [_centralMan scanForPeripheralsWithServices:[NSArray arrayWithObject:uuid] > options:nil]; > > I cannot find my peripheral, but when I use: > > _centralMan = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; > [_centralMan scanForPeripheralsWithServices:nil > options:nil]; > > …it shows up immediately. > > When I connect, I am able to discover/read/write to all the services I am expecting.

Cannot find BLE peripheral when scanning for specific services
by Mosher, Ben 26 Jun '12

26 Jun '12

When I use: CBUUID * uuid = [CBUUID UUIDWithString:@"1800"]; // GAP DEBUG_LOG(@"CBUUID: %@",uuid); // CBUUID: Generic Access Profile _centralMan = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; [_centralMan scanForPeripheralsWithServices:[NSArray arrayWithObject:uuid] options:nil]; I cannot find my peripheral, but when I use: _centralMan = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; [_centralMan scanForPeripheralsWithServices:nil options:nil]; …it shows up immediately. When I connect, I am able to discover/read/write to all the services I am expecting. My understanding is that GAP makes this possible. I have also tried CBUUID's for other services that I know are running (specifically "1804", TX power service), to no avail; the scan never discovers anything. Even though the services are running (I can communicate w/ them upon connecting), when I scan passing the service UUID array as `nil` and this delegate method is called... -(void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI { DEBUG_LOG(@"Found peripheral w/ UUID: %@ RSSI: %@ \n AdvData: %@",peripheral.UUID,RSSI,advertisementData); DEBUG_LOG(@"Services found: %d",peripheral.services.count); for (CBService * service in peripheral.services) { DEBUG_LOG(@"Found service: %@ w/ UUID %@",service, service.UUID); } } …it always reports "Services found: 0". Should I expect the `services` array to be populated w/ services found during the scan? (I assume this is at least partially possible, based on `scanForPeripheralsWithServices:[NSArray arrayWithObject:uuid] options:nil`.) Could this be a problem w/ my peripheral's service advertisements? Am I using the API incorrectly? Any guidance is much appreciated! :-) --Ben Mosher PS: I'm pretty green w/ Bluetooth.

RE: Cannot pair to our accessory from Ipad
by Ephram Cohen 26 Jun '12

Paul, If the message you are getting is the message I think it is... It means that Authentication was attempted and failed three times in a row. This is strictly an MFI issue. Something is wrong with your authentication process. I hope that I can say that here without getting into trouble.
