器件型号：CC1350

我正在尝试修改 simple_Peripheral CC1350示例项目的特征3、以便只能通过读取来访问它、当它获得读取命令时、它将通过无线方式发送一个3、000字节的阵列。 simple_Peripheral 示例项目的文档是分散的、并不能最好地描述每个宏的功能。当我尝试增加它发送的数据量时、发送22个字节是它在这里看起来最高的。

我希望避免编写每条数据中每条数据需要写入3、000 / 22字节= 136个特征。感谢您的帮助、

以下是我的项目中决定这一点的价值观：

在 simple_gatt_profile.h 中、第57行是这样的：

#define SIMPLEPROFILE_CHAR3_LEN           3000

在 simple_gatt_profile.c 中、我从第157行开始：

// Simple Profile Characteristic 3 Properties
static uint8 simpleProfileChar3Props = GATT_PROP_READ;

// Characteristic 3 Value
static uint8 simpleProfileChar3[SIMPLEPROFILE_CHAR3_LEN];
//static uint8 simpleProfileChar3 = 0;

// Simple Profile Characteristic 3 User Description
static uint8 simpleProfileChar3UserDesp[17] = "Characteristic 3";

在 simple_peripheral.c 中、我在第103行中有这个：
