core-bluetooth

I searched around a bit and just found this as a possible duplicate question: Multiple CBPeripheral's for same device My problem is: I have multiple services which all together have about 30-40 characteristics (Yes, I need all of them...). As starting point for dealing with CoreBluetooth I always used the Apple Sample Code ( CoreBluetooth Temperature Sensor ). Discovery and Service/Characteristic handling is divided into two classes and this works fine for just a few characteristics. But handling this huge amount of characteristics in one class is not what I understand under "good software

I'm having trouble getting Core Bluetooth to discover peripherals on iOS 8. Same code works fine on iOS 7 device. Initially I thought it would be a permissions issue since I had been doing some iBeacon work and there are some changes in Core Location permissions on iOS 8. I couldn't find anything online that helped with that however. Here is a link to a sample project that works fine for me on iOS 7 but not on iOS 8: https://github.com/elgreco84/PeripheralScanning If I run this project on an iOS 7 device it will log advertisement data for a number of devices around me. On iOS 8 the only output

I am trying to connect automatically to my AirPods with a simple app using BLE. I get the name of the device and the status to "connecting", but for some reason I can't connect to it. Function 'didConnect peripheral' is never triggered. I tried all different approaches from tutorials and from other posts, tried to store the peripheral data in an array to keep the reference but nothing seem to work. Is there any step which I can get some extra info between 'didDiscover' and 'didConnect'? Working in XCode 9.2, using Swift 4 and iOS 11.2 on iPhone. Here's my code: let deviceName = "AirPods de

I have a problem with the Bluetooth in Xcode. I can’t find a great solution on how to check if Bluetooth is on or not. I want just that. I searched around the web some solution, but nothing works for me. Any idea on how to check Bluetooth? I imported the CoreBluetooth class and I made this line of code: if CBPeripheralManager.authorizationStatus() == .denied { code } if CBPeripheralManager.authorizationStatus() == .authorized { code } Implement CBCentralManagerDelegate delegate for that. var manager:CBCentralManager! viewDidLoad() { // Or init() manager = CBCentralManager() manager.delegate =

Using CoreBluetooth I want to send data from iPhone to Mac. For this I wrote code like iPhone as 'Peripheral' and Mac as 'Central'. It works perfectly, but sometimes it disconnects directly and then it continuously connects and disconnects. Some times when it is trying to reconnect, In Central it directly calls 'didDisconnectPeripheral' delegate method. But some times it has error "The handle is invalid" in 'didUpdateNotificationStateForCharacteristic'. I referred all the links in net. But I am not able to solve this problem. I thought in iPhone it was storing Bluetooth cache. Please suggest a

What I'm trying to do is use the Apple Notification Center Service (ANCS) from my iPhone on my Mac. To make my Mac show up on in my iPhone's Bluetooth settings, I apparently need to use service soliciting. What I've tried so far is initiate a CBPeripheralManager on my Mac, add the ANCS service to it and start advertising. That doesn't seem to do it, as my Mac doesn't show up in my iPhone's Bluetooth settings. What I've also tried is initiate a CBCentralManager and start scanning, with the ANCS UUID in the CBCentralManagerScanOptionSolicitedServiceUUIDsKey key, which doesn't work either. Does

I am using the following code to write the 0xDE value for a Bluetooth Caracteristic (Reset Device) using the IOS Core Bluetooth : ... NSData *bytes = [@"0xDE" dataUsingEncoding:NSUTF8StringEncoding]; [peripheral writeValue:bytes forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse]; ... is there any mistake in my code because the value is not written properly? Try creating your data with an array of single byte values. const uint8_t bytes[] = {0xDE}; NSData *data = [NSData dataWithBytes:bytes length:sizeof(bytes)]; This is a useful approach for creating arbitrary constant

So from reading the CBPeripheralDelegate documentation, it appears that RSSI and peripheralDidUpdateRSSI:error: were deprecated with iOS 8. I noticed that my signal strength indicator was no longer being updated, so I did some research and found a new method ( [CBPeripheralDelegate peripheral:didReadRSSI:error:] ) that supposedly get called back asynchronously after calling the readRSSI method. Unfortunately, this method does not seem to get called back either, even though I did set the parent class as the CBPeripheral delegate. Has anyone else had issues with the iOS 8 CoreBluetooth updates?
