😃 Get

Peripheral(Server)

Bleu.addReceiver(Receiver(GetUserID(), get: { [weak self] (manager, request) in
    guard let text: String = self?.textField.text else {
        manager.respond(to: request, withResult: .attributeNotFound)
        return
    }
    request.value = text.data(using: .utf8)
    manager.respond(to: request, withResult: .success)
}))

Bleu.startAdvertising()

Central(Client)

let request: Request = Request(communication: GetUserID()) { [weak self] (peripheral, characteristic, error) in
    if let error = error {
        debugPrint(error)
        return
    }
    
    let data: Data = characteristic.value!
    let text: String = String(data: data, encoding: .utf8)!
    
    self?.centralTextField.text = text
}
Bleu.send([request]) { completedRequests, error in
    if let error = error {
        print("timeout")
    }
}
