  1. Hi there, I wanted to call the Bluetooth initWithDictionary and its option CBCentralManagerOptionShowPowerAlertKey; There is little information out there howto create the options for this call in the right way. CBCentralManager = interface(NSObject) ['{587D1855-5B53-43DA-91AF-AF9D93FFDB9F}'] ... function initWithDelegate(delegate: id; queue: dispatch_queue_t; options: NSDictionary): id; cdecl; overload; In XCode that looks quite straightforward, but what about Fmx ? let opts = [CBCentralManagerOptionShowPowerAlertKey: false] let manager = CBCentralManager(delegate: self, queue: nil, options: opts) Info's like this doesn't help much http://codeverge.com/embarcadero.delphi.firemonkey/help-rewrite-objective-c-proced/1046099 Using NSUserDefaults to access the info list properties seems not to work, returning nil. But is NSUserDefaults the right place to look for those keys ? var LDefaults: NSUserDefaults; LDict: NSDictionary; begin LDefaults := TNSUserDefaults.Wrap(TNSUserDefaults.OCClass.standardUserDefaults); LDict := LDefaults.dictionaryForKey( CBCentralManagerOptionShowPowerAlertKey ); // ! This (LDict) is nil if Assigned(lDict) then FCentralManager := TCBCentralManager.Wrap( TCBCentralManager.Alloc.initWithDelegate( GetObjectID, 0, LDict )) I used this function to get the key constant function CBCentralManagerOptionShowPowerAlertKey : NSString; begin Result := CocoaNSStringConst(libCoreBluetooth, 'CBCentralManagerOptionShowPowerAlertKey'); end; Other ways to construct this NSDictionary look to ugly to be true: LDict := TNSDictionary.Wrap( TNSDictionary.OCClass.dictionaryWithObjectsAndKeys( <<This is Pointer to object a nil-terminated list>>)); Maybe somebody can help with some useful hints, to find the right way to access such system options ?

    Triggers from Bluetooth Beacons

    Hi, I've got a beacon that has a button to trigger actions. I can configure the actions. For example, I when the user pushed the button the beacon advertises a URL. In Delphi, I can identify the beacon and I can read all the device info. What I can not figure out is how to identify that the user has triggered the button and thus the URL has been transmitted. Does anyone know how to do this? Thanks
  3. Hi, I tried all BlueTooth examples available with 10.3 Rio on my Mac (Xcode 10.1) but none of the them, compiled to Windows or macOS, work. Each time I click the scan button to list all available BlueTooth devices, I get a dialog box stating: Error BlueTooth device not found: disconnected or turned off. My BlueTooth card on my Mac is turned on and fully functional. Can anybody here use BlueTooth functionalities with Rio 10.3 on a Mojave macOS machine with Xcode 10.1? Or do you face the same problem? Thanks for any help. Steve
