TI中文支持网下载了评估SDK simplelink_cc2640r2_sdk_1_50_00_71_Evaluation。
但是如何测试 发送 和 接收 长广播呢？
以前的2540抓包工具好像抓不到，手机扫描也没发现。
只看到了老版本的BLE广播。
有做过相关测试的同行们，帮忙指点一下，感谢！
Qingsong Du：
发送和接收长广播功能，调出来了，把方法发出来，分享给需要的朋友：
1. 将SimplePeripheral_processGapMessage函数中的 advHandleLegacy 相关操作注释掉，这个是用来发31字节短广播的；
2. 将宏 GAPADV_PARAMS_AE_LONG_RANGE_CONN 中的 .primPhy 和 .secPhy 改为宏GAPADV_PARAMS_LEGACY_SCANN_CONN一样的值，
分别是 GAP_ADV_PRIM_PHY_1_MBPS 和 GAP_ADV_SEC_PHY_1_MBPS；
3. 修改广播数组长度，advertData[] 改为 advertData[255]。
这样再用Central工程接收广播，处理函数是SimpleCentral_processAppMsg。
这里有个问题，接收到的广播长度打印出来是245，而不是255，暂时不清楚具体原因。
注意：我用的是评估版的SDK，SDK simplelink_cc2640r2_sdk_1_50_00_71_Evaluation，不是正式发布的1.4版本。

请问，你的SimplePeripheral都做了哪些修改呢，我按你说的改了之后按键菜单都 调不出来了，方便把程序贴出来吗。。。。

”这里有个问题，接收到的广播长度打印出来是245，而不是255，暂时不清楚具体原因。“
前导和校验占用了：
• New Advertising channel extension PDU: ADV_EXT_IND– Allows up to 248 byte ADV payload by offloading payload to Data channels– Supports any PHY– Reduces traffic on ADV channels– Mandatory for Coded PHYs
除去前导和校验剩下的248byte。
如何使用请参照：
下面的的第二通道和上面的同学说的差不多。传统的BLE4.0抓包是抓不见的。

大神，那一楼同学说的配置方法正确不？我的咋不行啊

回复 z z46:
基本是正确的
建议你去申请SIMPLELINK-CC2640R2-BLE5-EVAL，里面有我们做好的程序。

我刚买了几块CC2652，啊，对了，我是在2652上实现的上述功能，修改的地方一样吗？

你要是CC2652就更简单了去看Simple Peripheral的程序：
*/static void SimplePeripheral_processGapMessage(gapEventHdr_t *pMsg){ switch(pMsg->opcode) { case GAP_DEVICE_INIT_DONE_EVENT: { bStatus_t status = FAILURE;
gapDeviceInitDoneEvent_t *pPkt = (gapDeviceInitDoneEvent_t *)pMsg;
if(pPkt->hdr.status == SUCCESS) { // Store the system ID uint8_t systemId[DEVINFO_SYSTEM_ID_LEN];
// use 6 bytes of device address for 8 bytes of system ID value systemId[0] = pPkt->devAddr[0]; systemId[1] = pPkt->devAddr[1]; systemId[2] = pPkt->devAddr[2];
// set middle bytes to zero systemId[4] = 0x00; systemId[3] = 0x00;
// shift three bytes up systemId[7] = pPkt->devAddr[5]; systemId[6] = pPkt->devAddr[4]; systemId[5] = pPkt->devAddr[3];
