上面这一段应该就是广播发现设备的程序么
可惜我找不到广播数据格式的代码？

比如我想按照厂商自定义数据: TYPE = 0xFF，厂商自定义的数据中，前两个字节表示厂商 ID，剩下的是厂商自己按照需求添加，里面的数据内容自己定义。
怎么修改？
对蓝牙协议刚刚看了点，不是很懂有点语无伦次

你除了广播数据外还需要建立连接吗？

bbccy

我表示也不太懂。。

要的是想改ADTYPE 建立连接虾哥

aci_gap_set_discoverable

按照这个格式感觉这段代码好像不对嘛广播类型是对的 ADV_IND 再往后好像不对

多谢虾哥已经解决广播数据包不是那个函数里面的哈哈
不过还有个问题请教下虾哥
就是广播查找设备的时

///OGF:OGF域,用来表示HCI命令的种类。HCI总共有7中类型的命令
rq.ogf = OGF_VENDOR_CMD;
///ocf:OCF对应每组命令组相应的命令。
///这里因为是厂家指定调试命令 spec里面没法查询到OCF
rq.ocf = OCF_GAP_SET_DISCOVERABLE;
rq.cparam = (void *)buffer;
rq.clen = indx;
rq.rparam = &status;
rq.rlen = 1;

复制代码

候用到OGF ,HCI层将Link Layer层提供的功能封装成Command和Event。
命令格式为什么选择OGF_VENDOR_CMD

再进入aci_gap_set_discoverable调用过的函数看看呢？

没深入研究过蓝牙协议
这个问题已经超出我的能力范围了

百度了一些有种说法是"0x3F的OGF被保留来用于vendor-specific(厂家特定)调试命令”
“OGF Range (6 bits): 0x00-0x3F (0x3F reserved for vendor-specific debug commands) ”
