Taking pictures using native Camera App with BLE Tag
by Fred Visticot 18 Apr '14

Hello, I seen some messages regarding this topic but I did not fully understand what is really possible to do with a PURE BLE solution (without MFI program) Use case: Using a BLE (CC2540 tag) to take a picture using the native iOS app Questions: - Is it possible ? - Mode to be used by the BLE firmware (peripheral or manager) ? - Profile to be used on the iPhone / iOS stack ? - How to control the native iOS Camera app ? _______________________________________________ Do not post admin requests to the list.

Re: Recommended Packet Sniffer?
by Roland King 18 Apr '14

Nordic has a free sniffer you load onto the eval kit board or dongle (PCA10000 or PCA10001), at least one of which you'll always get with any of their kits. The app they provide is windows (actually it's a command-line tool) which sends packets to wireshark. I love it and I like that it uses wireshark with which I am very familiar. It works under parallels just fine, I too am an OSX user. I neither like running windows much so I'm about 80% through an OSX version of the software. I initially asked Nordic for the protocol and they said no, so I picked it apart, it's pretty simple, and just last week Nordic open-sourced it which was rather nice of them so it's easier for me to finish it up. Their cheapest kit is $100 but obviously you get more than just a sniffer. If you end up going that way send me an off-list and I'll send you the OSX version when it's done. I've personally given up with TI who aren't even trying to do anything which isn't windows and IAR (in my opinion) whereas Nordic aren't there yet, but they are at least trying.

Hi Aaron 0x80 is the Keyboard Vol Up. It might be that you have to use F11 or F12 for the volume control. best matthias --- Dr. sc.

BLE: Discoverability of bonded devices
by Walter Stephan 14 Apr '14

14 Apr '14

Hi everyone, We are using a Nordic Semi nRF8001 in our device, and we are connecting to an iOS device using BLE with security (passkey). As long as the device is not bonded, it will advertise in Limited-Discoverable mode. That is, in the advertising packet, the limited-discoverable bit is set and the general-discoverable bit is cleared. Then we establish a bond with the iPhone by entering the passkey. If the connection is now cut, our device will again start advertising. Because a bond exists, it will be in Nondiscoverable mode, meaning that both the limited-discoverable bit and the general-discoverable bit are cleared. But in this case, other iOS devices will still see our device! I would think that this makes no sense, because we have a bond with a different iPhone. Is there a way to prevent these "foreign" bonded devices to show up when doing a scan in our app? Can we filter them based on the advertisement data? Unfortunately, the CBAdvertisementData... keys do not include the flags. A possibility would be to use Directed Advertising, but this is not supported by iOS. Using Manufacturer-specific data to indicate a bond in the advertising packet is another possibility, but we hoped that this functionality would be provided by the BLE API. Any help would be appreciated.

iOS: [EASession dealloc] - 139 unable to close session
by Alexander von Below 14 Apr '14

14 Apr '14

Hello good old list, the shiny new devforums don't seem to have a Bluetooth section, so I am back here. Hopefully, there are still people around :D I am wondering: When I create a new session with -[EASession initWithAccessory:forProtocol:], is there any way other than my very own housekeeping to tell if I already did that? If I create another session for the same device and the same protocols, the console spits out: 2014-04-14 11:34:06.598 BackgroundTest[9286:60b] ERROR - opening session failed 2014-04-14 11:34:06.599 BackgroundTest[9286:60b] ERROR - /SourceCache/ExternalAccessory/ExternalAccessory-243.10.8/EASession.m:-[EASession dealloc] - 139 unable to close session for _accessory=0x178203120 and sessionID=65536 Sometimes, this even happens when I just try to reconnect a device after loosing the connection. I don't see a "close" on the session, and deallocating the session does not seem to do the trick either. This is on iOS 7.1 (11D167). Could it be a bug in iOS? Could it be a bug in Firmware? Or have I just overlooked something in the docs? Any other information about that error is appreciated!

Hi, readValueForCharacteristic is a method of CBPeripheral not CBService. Regards Stephan _______________________________________________ Do not post admin requests to the list. They will be ignored.

read of Characteristic causes disconnect
by RAM KUMAR 11 Apr '14

11 Apr '14

I am implementing a central using on ios7 on an iPhone5s. I am able to scan for devices and can connect to the desired peripheral device. As part of the overall connection procedure, I also undertake the discovery procedure of service and characteristics. I have properties(obj-C) for the CBService - aService and CBCharacteristic aChar . As part of the didDiscoverServices , I store the service and as part of didDiscoverCharacteristicsForService and store the cache the characteristic which is has a property of 0x0A(Read/Write) - (void)peripheral:(CBPeripheral *)peripheral didDiscoverServices:(NSError *)error { CBUUID *svcUUID = [ CBUUID UUIDWithString:@"<SOME UUID>"]; for (CBService *service in peripheral.services) { NSLog(@"Service discovered - %@", service); if([service.UUID.data isEqualToData:svcUUID.data] ) { _aService = service; NSLog((@"Service found")); } } if(_aService) { dispatch_async(dispatch_get_main_queue(), ^{ [_targetDevice discoverCharacteristics:nil forService:t_aService]; }); } } - (void)peripheral:(CBPeripheral *)peripheral didDiscoverCharacteristicsForService:(CBService *)service error:(NSError *)error { CBUUID *charUUID = [ CBUUID UUIDWithString:@"<some UUID>"]; for( CBCharacteristic *cs in service.characteristics) { NSLog(@"Characteristics discovered - %@", cs); if([cs.UUID.data isEqualToData:charUUID.data] ) { _aChar = cs; NSLog(@"Characteristic %@ Found",cs); // This works btw [peripheral readValueForCharacteristic:_aChar]; break; } } } Now I have a button that i use to read the char . In the button handler, I use the following call to read the characteristic for the service . -(IBAction) buttonDown:(id)sender { // immediate disconnection after this ! [_aService readValueForCharacteristic:_aChar]; } I immediately see a disconnect. Any clues as to why this might me occurring? On the other hand, I observe that if I invoke this same request in the didDiscoverCharacteristicsForService then the calls succeeds and the data is available. _______________________________________________ Do not post admin requests to the list.
