芯片：CC2652
工程：ProjectZero
过程：修改了projectzero里面的dataservice.c，打开了以送Notification，并把DataService_SetParameter函数放到了按键处理函数中，期待每次按键能够触发发送Notification，但是没有效果T_T
问题：打开了Notification后，当DataService_SetParameter被调用时，是否projectzero会主动发送当前参数值到连接的BTool上？
我看到打印的log显示connhandle是fffff，而与BTool的connhandle是0,所以此处是否有问题？
static void buttonDebounceSwiFxn(UArg buttonId)
{
uint8_t tempString_r[]="Button released.",tempString_p[]="Button pressed.";
switch(buttonId)
{
case Board_PIN_BUTTON0:
// If button is now released (buttonPinVal is active low, so release is 1)
// and button state was pressed (buttonstate is active high so press is 1)
if(buttonPinVal && button0State)
{
// Button was released
buttonMsg.state = button0State = 0;
sendMsg = TRUE;
DataService_SetParameter(DS_STREAM_ID, sizeof(tempString_r), tempString_r);
Log_info0("Board_PIN_BUTTON0_r\r\n");
}
else if(!buttonPinVal && !button0State)
{
// Button was pressed
buttonMsg.state = button0State = 1;
sendMsg = TRUE;
DataService_SetParameter(DS_STREAM_ID, sizeof(tempString_p), tempString_p);
Log_info0("Board_PIN_BUTTON0_p\r\n");
}
break;
...
}
}
其中红色加粗部分是我添加上去的
ProjectZero与BTool连接后,直接按按键0,BTool端显示的数据没有变化,然后利用BTool修改CCCD为notification及indication,再按键,projectzero就死机了T_T
BTool的修改见上图
求大神解答.
1.我想利用notification向BTool同步本地数据这样可行吗?这种方式是由projectzero主动发起更新数据请求吗?
2.上述工程哪里不对啊,为什么会出现按键后未更新以及修改stream CCCD配置后按键死机的情况呢?
