This is not a BLE Manager for your phone. There are plenty of those out there. BluetoothMessageProtocol provides functions for encoding and decoding Bluetooth Characteristic data.

Installation

BluetoothMessageProtocol is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'BluetoothMessageProtocol'

Swift Package Manager:

    dependencies: [
        .package(url: "https://github.com/FitnessKit/BluetoothMessageProtocol", from: "0.13.0")
    ]

How to Use

Each Bluetooth Characteristic has an encode and decode method. When you receive the data from a sensor you call the static decode method to turn the data into a Characteristic Object as seen below in the example:

func peripheral(_ peripheral: CBPeripheral, didUpdateValueFor characteristic: CBCharacteristic, error: Error?) {

    if let sensorData = characteristic.value {
        if characteristic.uuid.uuidString == CharacteristicHeartRateMeasurement.uuidString {
            doDecodeHRMess(sensorData: sensorData)
        }

        if characteristic.uuid.uuidString == CharacteristicBodySensorLocation.uuidString {
            doDecodeBody(sensorData: sensorData)
        }
    }
}

func doDecodeHRMess(sensorData: Data) {

    do {
        let hrData = try CharacteristicHeartRateMeasurement.decode(data: sensorData)

        print("HR: \(hrData.heartRate)")

    } catch  {
        print(error)
    }
}

func doDecodeBody(sensorData: Data) {

    do {
        let hrData = try CharacteristicBodySensorLocation.decode(data: sensorData)

        print("Location: \(hrData.sensorLocation.stringValue)")

    } catch  {
        print(error)
    }
}
