![]() Regarding table view, is there a really simple way of doing it?Īdd new file (cocoa class table view controller) and link to the view controller Dispose of any resources that can be recreated. Print("the characteristic is sent over here: (\"(value)") Let value = characteristic.value!.withUnsafeBytes If let characterArray = service.characteristics as !įunc peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?)

I only have the one view controller: import UIKitĬlass ViewController: UIViewController, CBCentralManagerDelegate, var BLEStatus: var ConnectionLabel: UILabel! However I am unable to control it so that when I press the button the table view pops up and you can choose which device to connect to (at the moment it just defaults to choosing one)įurthermore, how do I set it so that I can choose what info to send to the bluetooth and in turn to the Arduino? In the past I have done this, and I am able to send ASCII characters and that works well for me, but how do i send value from xCode? The connection to the bluetooth I can do. Once connected, back on the home page you can press turn on and turn off for the LED light. When ‘Connect’ is pressed it goes to the second page where you can choose the bluetooth device to connect to. I would like it so that my app is set up so I have a homepage, in the navigation bar at the top right there would be a connect button. You can then choose which you would like to connect to. The idea is that I press a button and then it shows what bluetooth devices (Hm-10)are available. The app would be used to turn on and turn off an led light. I have only been using Xcode for a short while. I am making an app to be used with an Arduino but I am struggling bit. For BT Classic, just open the Bluetooth settings view and it will search for BT Classic devices. It scans all the BLE devices in the area if they are advertising. You can do some quick manual testing for BLE by downloading an app like BLExplr or similar. You might be better off checking Wifi signals as many phones have their personal hotspot broadcasting. For most purposes, a BT address can still be considered a unique identifier but wanted to mention it.Īpple devices do support both Bluetooth Classic and BLE but from my experience you won’t be able to detect them by default. Its hard to say.Īlso, just a note that the MAC addresses discovered were technically Bluetooth addresses. The addresses grabbed may have been from Bluetooth peripherals like car’s built-in BT or headsets. The website mentioned about grabbing MAC addresses while next to a busy highway. But again this won’t necessarily detect iOS devices unless a specific app is broadcasting. The link you referenced indicated a BT Classic module. An iOS device can advertise as a slave but again it would need to be a 3rd party app doing it as I don’t know of any built-in Apple applications supporting it. And actually they aren’t even performing master operations unless a specific app is telling them to. They are typically used as the Client (master) and therefore are externally silent. This is because most iOS devices are not advertising as BLE Servers (slaves). Using BLE discoveries to detect iOS devices in the area may not work so well.
