UDPSender

UDPSender

NIO-based UDP send-receiver

enter:

• Instruction byte array
• [Target port number]
• [Broadcast sending by default, IP sending can be specified]
• [Default only sends once, you can specify the number of sending times and delay sending]

【】indicates optional functions and can not be used

Output:

• UDPReuslt result object (including the other party's IP address, result array [array of byte type])

import

Add the following code to your project app/build.gradle

    dependencies {
       ...

    }

How to use

Get started quickly

 UDPSender . getInstance ()
                . setInstructions ( byteAraary )
                . setTargetPort ( port )
                . start ( new UDPResultCallback () {
                    @ Override
                    public void onNext ( UDPResult result ) {
                        //do something
                    }
                });

Complete demo

 UDPSender . getInstance ()
                . setInstructions ( byteAraary ) //设置发送的指令[可为空]
                . setReceiveTimeOut ( 70 * 1000 ) //设置接收超时时间[可不写，默认为60s]--超时70s就停止任务
                . setTargetPort ( port ) //设置发送的端口[必写]
                . setLocalReceivePort ( port ) //设置本机接收的端口[可不写，默认为目标端口]
                . setTargetIp ( "192.168.1.150" ) //设置目标ip地址，[可不写，默认广播]
                . schedule ( 2 , 3000 ) //执行2次，间隔三秒执行（上一次结束到下一次开始的时间）
                . start ( new UDPResultCallback () {

                    @ Override
                    public void onStart () {
                        //请求开始的时候回调
                    }

                    @ Override
                    public void onNext ( UDPResult result ) {
                        //每收到一个结果的时候就回调
                    }

                    @ Override
                    public void onCompleted () {
                        //请求结束的时候回调
                    }

                    @ Override
                    public void onError ( Throwable throwable ) {
                        //当发生错误的时候回调
                    }
                });

Only receive data

 UDPSender . getInstance ()
                . setLocalReceivePort ( 9988 ) //接收端口
                . start ( new UDPResultCallback () {
                    @ Override
                    public void onStart () {
                        ELog . hdl ( "开始了" );
                    }

                    @ Override
                    public void onNext ( UDPResult result ) {
                        ELog . hdl ( "收到结果" + result );
                    }

                    @ Override
                    public void onError ( Throwable throwable ) {
                        ELog . hdl ( "出错" + throwable );
                    }

                    @ Override
                    public void onCompleted () {
                        ELog . hdl ( "完成" );
                    }
                });

Close task

 UDPSender . getInstance (). stop ();

UDPReslt

 public class UDPResult {
    /**
     * 对方ip地址
     */
    private String ip ;
    /**
     * 对方返回的结果
     */
    private byte [] resultData ;
}

Historical update record

v2.X version

v2.0.2 (2017.10.27)

• [Fix] Data cleaning is not timely, resulting in dirty data

v2.0.1

• [Fix] The bug that the other party’s port can only be used as its own receiving port
• [Optimization] The underlying library code has been optimized and is relatively mature and can be used in production environments.

Warm reminder: It is not recommended to use v1.X version. It is recommended to use the latest version. The usage method remains unchanged.

v1.3.9

• [Fix] The sudden stop when calling a scheduled task causes the current task to be stopped immediately when the task is restarted next time.

• [bug] Only the sender can specify the port, bug, do not use this version

v1.3.8

• 【Fix】Fix crash under special circumstances

• [bug] Only the sender can specify the port, bug, do not use this version

• [Fix] Automatically close related interfaces when the task ends

• [bug] Only the sender can specify the port, bug, do not use this version

v1.3.6

• [Fix] Call onCompleted method multiple times

• [bug] Only the sender can specify the port, bug, do not use this version

v1.3.5

• [Fix] Closing the task (UDPSender.getInstance().stop()) does not use the onCompleted method

• [New] Set target IP method (default broadcast form)

• [bug] Only the sender can specify the port, bug, do not use this version
