BLU蓝牙上位机求指导

很想将原来的上位机全部换为AARDIO,支持jacen.就是不会回调

大致看了下, 回调在aardio里根据调用方式stdcall的有

thread.tostdcall

raw.tostdcall

看你那个dll是stdcall,用对应的转换下aar里面的函数成为函数指针即可.

可以参考上面的例子, 还有aardio的sio串口库里其实也有这样的回调, 先琢磨下, 试试手, 还是不行的话, 贴上你的代码还有运行遇到的问题.

自己研究出来也是个学习过程, 比别人直接给代码记忆深刻. O(∩_∩)O~

回复#4 @chenqiang :

看你上面的callback定义, 貌似没啥问题,

dll引用是stdcall,你拼错了,void*可以用ADDR, UCHAR用BYTE, 

另外你这里演示的是open的callback, 函数名最好一致

我这里调用dll会提示少了个api-ms-xxxxxx.dll, 网上下载了个还是不行, 没法测试, 可能需要注意的地方是raw.tostdcall, 如果调用会报错, 那么可以改用多线程的thread.tostdcall,当然如果用了thread,那么callback函数里就要加一句import console , 才能输出信息. 你自己再测测.

这里void*

var blu=raw.loadDll("res/blu.dll",,"stdcall")
FunDevConnChangeCallBack = function (a,b) {
     console.log(a,b);	
}
ConnectStatus=raw.tostdcall( FunDevConnChangeCallBack,"void(ADDR,BYTE)");
WCHBLEOpenDevice(bmac,ConnectStatus)

没设备测写了个简单的测试: 

import win.ui;
/*DSG{{*/
mainForm = win.form(text="BLU蓝牙PC上位机";right=657;bottom=368)
mainForm.add(
button={cls="button";text="Button";left=376;top=276;right=602;bottom=331;z=1};
button2={cls="button";text="Button";left=79;top=268;right=305;bottom=323;z=2}
)
/*}}*/

import console;
console.open()


var dll = raw.loadDll("/WCHBLEDLL.dll","dddd","stdcall");
//pFunDevConnChangeCallBack = dll.api("pFunDevConnChangeCallBack","void(ADDR,BYTE )" )
WCHBLEEnumDevice=dll.api("WCHBLEEnumDevice","void(INT,string,struct&,INT&)" )
WCHBLEOpenDevice=dll.api("WCHBLEOpenDevice","ADDR(string deviceID,pointer ConnectStatus)" )
WCHBLECloseDevice = dll.api("WCHBLECloseDevice","void(ADDR)" )
FunDevConnChangeCallBack = function (a,b) {
    import console
     console.dump(a,b); 
}
ConnectStatus=raw.tostdcall( FunDevConnChangeCallBack,"void(ADDR,BYTE)");
var dev,num = WCHBLEEnumDevice(2000,"",{BYTE name[260];BYTE devID[260];int rssi},10);
console.log(num);
console.dump(dev)
console.log(dev.name)
console.log(dev.devID)
var devHwnd;// = WCHBLEOpenDevice(dev.devID,ConnectStatus)

mainForm.button.oncommand = function(id,event){
	 WCHBLECloseDevice(devHwnd);
}

mainForm.button2.oncommand = function(id,event){
	devHwnd = WCHBLEOpenDevice(dev.devID,ConnectStatus)
	if(devHwnd==null){
		console.log("打开失败")
	}else {
		console.log("ok")
	}
	
}

mainForm.show();
win.loopMessage();

用蓝牙鼠标测试,能连接能显示, 但是回调的那个并没有执行, 我估计应该是dll这个回调有问题,或者还没理解这个dll咋用....
