TI中文支持网大家好：
我们购买了BT-MSPAUDSOURCE Tools Bluetooth and MSP430 Audio开发板(MSP430F5229)，希望提供中断处理程序（最好主设备，从属设备各一套）；最好完整一些（宏定义，初始化，执行完整部分）
谢谢！
Susan Yang：
有些不太理解您的意思。能否详细描述一下
您现在是说的哪部分的中断处理程序？
之前已经在相关帖子内回复了

SuSan, 您好：
按照“蓝牙传输”的理论， 我们希望蓝牙主设备采用“广播方式”发出数据包；蓝牙从设备接收到数据，产生中断，解析数据包内容，进行相应处理！
我们使用的MSP430F5229芯片（开发板是：BT-MSPAUDSOURCE Tools Bluetooth and MSP430 Audio开发板），我们希望以它为基础的
蓝牙（从属设备）中断处理程序

大家好：
您看如下的MSP430的蓝牙接收中断处理程序，改装时注意几项？
#pragma vector = USCIAB0RX_VECTOR //接收中断__interrupt void USCI0RX_ISR(void)//中断程序，串口通讯的规则设计{ while ( !(IFG2&UCA0TXIFG) ); //确保发送缓冲区准备好 a=UCA0RXBUF;
if (a=='1') { b++; flag=1;
P1OUT^=BIT0; }
UCA0TXBUF=UCA0RXBUF; IFG2 &=~ UCA0TXIFG; //接收指示灯状态改变 }

谢谢！ 我将仔细研读

大家好：
经过“理论“确认，USCI_A0_VECTOR（HCI_RX_1V8_CC—->MSP430F5229的37管脚：P3.3/UCA0TXD)正是我们蓝牙的主接收端口！
但我们将这个中断处理程序写入后， （
请参考：
// Echo back RXed character, confirm TX buffer is ready first
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=USCI_A0_VECTOR
__interrupt void USCI_A0_ISR(void)
#elif defined(__GNUC__)
void __attribute__ ((interrupt(USCI_A0_VECTOR))) USCI_A0_ISR (void)
#else
#error Compiler not supported!
#endif
{
switch(__even_in_range(UCA0IV,4))
{
case 0:break; // Vector 0 – no interrupt
case 2: // Vector 2 – RXIFG
while (!(UCA0IFG&UCTXIFG)); // USCI_A1 TX buffer ready?
UCA0TXBUF = UCA0RXBUF; // TX -> RXed character
break;
case 4:break; // Vector 4 – TXIFG
default: break;
}
}）
程序下载后就跑飞了， 不能跳转到main()入口处！
如何破解？

单从这段代码看，是没有问题的。方便的话建议提供完整代码或工程。

回复 灰小子:
谢谢！ 请帮参考！
奇怪的是： 如果没有加上那段（#pragma vector=USCI_A0_VECTOR……）中断处理程序，一切正常！

回复 user5274273:
大家好：在这个应用中，我们希望解决如下问题：1). 用“GAP_LE_Perform_Scan(”获得当前范围内的“蓝牙设备”，用中断处理程序"USCI_A0_ISR"来获得它们的“设备名称”2). 指定自己为“主设备”， 其它特定的设备为“从设备”3). “主设备”广播发送数据，同步“从设备”
请问我们的实现策略合理吗？
Susan Yang：
回复 user5274273:
1您可以使用GetRemoteName 来获取设备的名称
/* The following function is responsible for querying the Bluetooth*//* Device Name of the specified remote Bluetooth Device.This*//* function returns zero on successful execution and a negative value*//* on all errors.2 您可以使用HCI_Role_Discovery来查看当前的role
static Boolean_tLocalDeviceIsMaster;/* Boolean that tells if the local *//* device is the master of the*//* current connection.*/
3 您是想通过广播来同步?
另外建议您若是遇到新问题请重新发帖，以便于回复与查看，谢谢
