我正在尝试将手机用作GSM调制解调器。我使用SMSLib通过此调制解调器发送和接收SMS。
问题是,当我的手机(GSM调制解调器)收到短信时,我没有通过SMSLib进行通知。但是,例如,整体代码很好,可以在GSM调制解调器收到呼叫时通知我。
我的代码没有任何错误,因为我仅使用SMSLib示例代码来接收消息。
SMSLib示例代码为:

public class TestSinaRec
{
    public void doIt() throws Exception
    {
        // Define a list which will hold the read messages.
        List<InboundMessage> msgList;
        // Create the notification callback method for inbound & status report
        // messages.
        InboundNotification inboundNotification = new InboundNotification();
        // Create the notification callback method for inbound voice calls.
        CallNotification callNotification = new CallNotification();
        //Create the notification callback method for gateway statuses.
        GatewayStatusNotification statusNotification = new GatewayStatusNotification();
        OrphanedMessageNotification orphanedMessageNotification = new OrphanedMessageNotification();
        try
        {
            System.out.println("Example: Read messages from a serial gsm modem.");
            System.out.println(Library.getLibraryDescription());
            System.out.println("Version: " + Library.getLibraryVersion());
            // Create the Gateway representing the serial GSM modem.
            SerialModemGateway gateway = new SerialModemGateway("modem.com4", "COM4", 115200, "Nokia", " 6303i");
            // Set the modem protocol to PDU (alternative is TEXT). PDU is the default, anyway...
            gateway.setProtocol(Protocols.PDU);
            // Do we want the Gateway to be used for Inbound messages?
            gateway.setInbound(true);
            // Do we want the Gateway to be used for Outbound messages?
            gateway.setOutbound(true);
            // Let SMSLib know which is the SIM PIN.
            gateway.setSimPin("0444");
            // Set up the notification methods.
            Service.getInstance().setInboundMessageNotification(inboundNotification);
            Service.getInstance().setCallNotification(callNotification);
            Service.getInstance().setGatewayStatusNotification(statusNotification);
            Service.getInstance().setOrphanedMessageNotification(orphanedMessageNotification);
            // Add the Gateway to the Service object.
            Service.getInstance().addGateway(gateway);
            // Similarly, you may define as many Gateway objects, representing
            // various GSM modems, add them in the Service object and control all of them.
            // Start! (i.e. connect to all defined Gateways)
            Service.getInstance().startService();
            // Printout some general information about the modem.
            System.out.println();
            System.out.println("Modem Information:");
            System.out.println("  Manufacturer: " + gateway.getManufacturer());
            System.out.println("  Model: " + gateway.getModel());
            System.out.println("  Serial No: " + gateway.getSerialNo());
            System.out.println("  SIM IMSI: " + gateway.getImsi());
            System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
            System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
            System.out.println();
            // In case you work with encrypted messages, its a good time to declare your keys.
            // Create a new AES Key with a known key value.
            // Register it in KeyManager in order to keep it active. SMSLib will then automatically
            // encrypt / decrypt all messages send to / received from this number.
            //Service.getInstance().getKeyManager().registerKey("+306948494037", new AESKey(new SecretKeySpec("0011223344556677".getBytes(), "AES")));
            // Read Messages. The reading is done via the Service object and
            // affects all Gateway objects defined. This can also be more directed to a specific
            // Gateway - look the JavaDocs for information on the Service method calls.
            msgList = new ArrayList<InboundMessage>();
            Service.getInstance().readMessages(msgList, MessageClasses.ALL);
            for (InboundMessage msg : msgList)
                System.out.println(msg);
            // Sleep now. Emulate real world situation and give a chance to the notifications
            // methods to be called in the event of message or voice call reception.
            System.out.println("Now Sleeping - Hit <enter> to stop service.");
            System.in.read();
            System.in.read();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        finally
        {
            Service.getInstance().stopService();
        }
    }

    public class InboundNotification implements IInboundMessageNotification
    {
        public void process(AGateway gateway, MessageTypes msgType, InboundMessage msg)
        {
            if (msgType == MessageTypes.INBOUND) System.out.println(">>> New Inbound message detected from Gateway: " + gateway.getGatewayId());
            else if (msgType == MessageTypes.STATUSREPORT) System.out.println(">>> New Inbound Status Report message detected from Gateway: " + gateway.getGatewayId());
            System.out.println(msg);
        }
    }

    public class CallNotification implements ICallNotification
    {
        public void process(AGateway gateway, String callerId)
        {
            System.out.println(">>> New call detected from Gateway: " + gateway.getGatewayId() + " : " + callerId);
        }
    }

    public class GatewayStatusNotification implements IGatewayStatusNotification
    {
        public void process(AGateway gateway, GatewayStatuses oldStatus, GatewayStatuses newStatus)
        {
            System.out.println(">>> Gateway Status change for " + gateway.getGatewayId() + ", OLD: " + oldStatus + " -> NEW: " + newStatus);
        }
    }

    public class OrphanedMessageNotification implements IOrphanedMessageNotification
    {
        public boolean process(AGateway gateway, InboundMessage msg)
        {
            System.out.println(">>> Orphaned message part detected from " + gateway.getGatewayId());
            System.out.println(msg);
            // Since we are just testing, return FALSE and keep the orphaned message part.
            return false;
        }
    }

    public static void main(String args[])
    {
        TestSinaRec app = new TestSinaRec();
        try
        {
            app.doIt();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}


程序输出例如:


  调制解调器的网关状态更改4,旧:已停止->新:正在启动
   modem.com的网关状态更改4,旧:开始->新:开始
  
  调制解调器信息:制造商:诺基亚型号:诺基亚6303i classic
  序列号:35538​​2041051833 SIM IMSI:**屏蔽**信号电平:

  正在睡觉-点击停止服务。
  从网关检测到新呼叫:modem.com4:+989111007483
  从网关检测到新呼叫:modem.com4:+989111007483


当我搜索此问题时,我发现了这一点:


  此方法的正确操作取决于未经请求的调制解调器
  指示以及CNMI命令的正确操作。如果你
  看到您没有使用回调方法接收消息,
  可能是调制解调器指示未正确设置。


所以我用诺基亚6303i而不是我最初使用的诺基亚5200来更换手机(GSM调制解调器),但问题仍未解决。
所以现在我真的不知道选择其他手机是否可以解决问题?或者我应该寻找一个更好,更合理的解决方案。

感谢您为解决此问题所提供的帮助。

最佳答案

好吧,我唯一能想到的就是您正在启动Service,然后将SMS发送到调制解调器。因此,该行将不会被调用:Service.getInstance().readMessages(msgList, MessageClasses.ALL);。但是,您仍然应该收到一条新消息已到达调制解调器的通知。

尝试实现InboundNotification以在调制解调器感测到任何新消息时提取消息。通过重写process()方法来执行此操作。

但是,这也可能是由于您实际上过早按下<Enter>所致。如评论所说;您必须等待,以便让notifications方法有机会被调用。

有时候,它只是那样愚蠢。让我知道它是否有帮助或者我是否完全误解了您的问题。我本人正在开发多调制解调器网关,所以很乐意提供帮助。
