CC2540 advertData 可利用字节数？

您好，我想在 advertData[]中添加自己的数据，比如温度、日期、电压等等，我想知道 advertData[]中哪些数据是必须的我必须保留？

我曾试过将 advertData[]中全部换成自己的数，发现最大有31个字节。期待TI专家的帮助，谢谢！

static uint8 advertData[] =
{
// Flags; this sets the device to use limited discoverable
// mode (advertises for 30 seconds at a time) instead of general
// discoverable mode (advertises indefinitely)
//0x02, // length of this data
// GAP_ADTYPE_FLAGS,
// DEFAULT_DISCOVERABLE_MODE | GAP_ADTYPE_FLAGS_BREDR_NOT_SUPPORTED,

// service UUID
// 0x03, // length of this data
// GAP_ADTYPE_16BIT_MORE,
// LO_UINT16( THERMOMETER_SERV_UUID ),
// HI_UINT16( THERMOMETER_SERV_UUID ),

};

advertising 数据是有一定合适要求的哦.

请看gap.h

看一下里面的 @defgroup GAP_ADTYPE_DEFINES GAP Advertisment Data Types

下面有类型定义. 注意看一下下面的类型定义哈.
