advertisement string does not work

hi i want to match advertisement string for example from peripheral side it advertise "gtpV5nm8Znm" and central side it scan for "gtpV5nm8Znm" if both match then central able to write data so how is it possible i put this string with let configuration = try! Configuration(services: [service], advertisement: "1004FD87-820F-438A-B757-7AC2C15C2D56") but it give me error

Add write requests without response

Now writing is only possible with response. It would be nice to have possibility of choosing type of write requests, as some peripherals might advertise characteristic with only writeWithoutResponse property.

can i measure distance from central to peripheral?

Crash when tap Advertisement button on the first screen.

this framework support cross-platform?

actually i want to develop bluetooth low energy where central application send data to peripheral and that peripheral app is on ios and android platform so is this possible using your library

Possible issue

Hi!

I installed library using cocoapods. It is not compiled

place internal extension AdvertisementData

method internal var data: Any? {

  case .servicesUUIDs(let uuid):
            return try? [CBUUID(uuidString: uuid)] -> Maybe [try? CBUUID(uuidString: uuid)]

With best wishes

Compilation Errors in Xcode 11.2

I get the following error,

/Users/rlotech/Documents/BlueSwift-master/Framework/Source Files/Command/Command.swift:30:5: 'internal' modifier is redundant for instance method declared in an internal extension

Compilation errors in Xcode 10.3

I unable to compile current master with Xcode 10.3, because of errors:

Write successfully occurs, but the handler is not called

I am attempting to write to a characteristic. The first time I run the code below, it works and my peripheral is written to and I receive a callback handler for "write" function with no error. Then, when I attempt to run the same exact code a second time, the peripheral is written to but I do not receive a callback handler.

Note: I am using the "develop" branch because the changes to read/write validation were necessary to make the write work in the first place... If you can merge this into master I would much appreciate it.

Here is the example code:

        let characteristic1 = try! Characteristic(uuid: "EXAMPLE")
        let characteristic2 = try! Characteristic(uuid: "EXAMPLE")
        let service = try! Service(uuid: uuid, characteristics: [characteristic1, characteristic2])
        let configuration = try! Configuration(services: [service], advertisement: uuid)
        let peripheral = Peripheral(configuration: configuration)

        // connect to the peripheral
        connection.connect(peripheral) { [weak self] error in
            guard error == nil else {
                return
            }
            
            let command = Command.int8(1)
            

            // write command to characteristic1
            peripheral.write(command: command,
                             characteristic: characteristic1,
                             type: .withResponse)
            { (error) in
                // on second run, this handler code does not execute
                guard error == nil else {
                    // if error writing, read characteristic2
                    peripheral.read(errorCharacteristic) { (result, error) in
                        guard let result = result else {
                            self?.connection.disconnect(peripheral)
                            return
                        }
                        
                        var resultNumber: UInt8 = 0
                        result.copyBytes(to:&resultNumber, count: MemoryLayout<UInt8>.size)
                        print(resultNumber)
                        self?.connection.disconnect(peripheral)
                    }
                    return
                }
                
                // always disconnect
                self?.connection.disconnect(peripheral)
            }
        }

Swift Package Manager support

SPM support would be great for this
