# **【AB32VG1开发】基于RT-Thread 中科蓝讯AB32VG1 BLE开发例程讲解**

------------

中科蓝讯最近出的SDK(bluetrum_sdk) V1.1.0，支持了BLE开发，目前官方还没有正式文档，我来摸索一下吧

------------

##  **安装最近SDK**
操作步骤详细请参阅： [基于RT-Thread的AB32VG1开发环境搭建](http://bbs.sunsili.com/thread-225595-1-1.html)

![ab32_sdk.JPG](https://oss-club.rt-thread.org/uploads/20211204/b1663e8feac9addc46e256b3334aa12a.jpg.webp)

选择中科蓝讯AB32VG1开发板最新SDK(bluetrum_sdk) 1.1.0安装

## **建RT-Thread工程**

操作步骤详细请参阅： [基于RT-Thread的AB32VG1开发环境搭建](http://bbs.sunsili.com/thread-225595-1-1.html)
注意选择最新SDK 1.1.0

### **配置工程**

操作步骤详细请参阅： [基于RT-Thread的AB32VG1开发环境搭建](http://bbs.sunsili.com/thread-225595-1-1.html)
配置详情如下：
![ab32_prj_config.JPG](https://oss-club.rt-thread.org/uploads/20211204/b4a2b77c84a105bbf6d8e86eb0391280.jpg.webp)

开启：
    宏: [SOC_AB32VG1]
    宏: [PKG_USING_BLUETRUM_NIMBLE]
    宏: [BSP_USING_TIM]（这后面加的，因为出现这个了定时报告数据时运行错误：(rt_object_get_type(&timer->parent) == RT_Object_Class_Timer) assertion failed at function:rt_timer_stop, line number:502 ）我以为加上TIMER模块，就加了，但是还是没解决。

配置后，保存会出现错误：local variable 'get_git_root' referenced before assignment Operation failed.这里不管它，编译时看看具体是哪里同， 我们再修改。

### **修改代码**

首先熟悉一下BLE_SDK代码目录：
![AB32VG1_ble_dir.png](https://oss-club.rt-thread.org/uploads/20211204/d3c93794a2f6994c4328958a16b902ec.png.webp)

### **修改mac_addr**

工程目录下：
    packages\bluetrum_sdk-latest\bluetrum_nimble\porting\npl\rtthread\src\ble_platform.c
![AB32_BLE._mac_addr.JPG](https://oss-club.rt-thread.org/uploads/20211204/fc466fa5934f49568bdb54278d072451.jpg.webp)

我修改如下:
```c
void bt_get_local_bd_addr(uint8_t *addr)
{
    uint8_t addr_table[6] = {0x41, 0x42, 0x18, 0x58, 0x68, 0x88};  //mac_addr是6bytes, SDK代码里只写了5个数据
    memcpy(addr, addr_table, 6);
}
```
    注意：mac_addr是6bytes, SDK代码里只写了5个数据，这是疏漏还是有意为之

### **修改BLE_name(名字）**

工程目录下：
    \packages\bluetrum_sdk-latest\bluetrum_nimble\apps\blehr\src\blehr.c
![AB32_BLE._name.JPG](https://oss-club.rt-thread.org/uploads/20211204/4354976834db3e72d033a6451ec161de.jpg.webp)
我修改如下:
```c
static const char *device_name = "Silicon_blehr_sensor";
```
    注意：不能是中文，中文会找不到设备

### **修改服务及设备信息**
工程目录下：
packages\bluetrum_sdk-latest\bluetrum_nimble\apps\blehr\src
![ab32_ble_srv_device_info.JPG](https://oss-club.rt-thread.org/uploads/20211204/03a69944037e85e1a44b01ae6297cb10.jpg.webp)
我修改如下:
```c
static const char *manuf_name = "谷动谷力";  //Sunshine Silicon";可以中文,但长度限制了,没有找到哪里限制了
static const char *model_num = "SunSilicon HR Sensor";
```
    
```C
static const struct ble_gatt_svc_def gatt_svr_svcs[] = {
    {
        /* Service: Heart-rate */
        .type = BLE_GATT_SVC_TYPE_PRIMARY,
        .uuid = BLE_UUID16_DECLARE(GATT_HRS_UUID),
        .characteristics = (struct ble_gatt_chr_def[]) { {
            /* Characteristic: Heart-rate measurement */
            .uuid = BLE_UUID16_DECLARE(GATT_HRS_MEASUREMENT_UUID),
            .access_cb = gatt_svr_chr_access_heart_rate,
            .val_handle = &hrs_hrm_handle,
            .flags = BLE_GATT_CHR_F_NOTIFY,
        }, {
            /* Characteristic: Body sensor location */
            .uuid = BLE_UUID16_DECLARE(GATT_HRS_BODY_SENSOR_LOC_UUID),
            .access_cb = gatt_svr_chr_access_heart_rate,
            .flags = BLE_GATT_CHR_F_READ,
        }, {
            0, /* No more characteristics in this service */
        }, }
    },

{
        /* Service: Device Information */
        .type = BLE_GATT_SVC_TYPE_PRIMARY,
        .uuid = BLE_UUID16_DECLARE(GATT_DEVICE_INFO_UUID),
        .characteristics = (struct ble_gatt_chr_def[]) { {
            /* Characteristic: * Manufacturer name */
            .uuid = BLE_UUID16_DECLARE(GATT_MANUFACTURER_NAME_UUID),
            .access_cb = gatt_svr_chr_access_device_info,
            .flags = BLE_GATT_CHR_F_READ,
        }, {
            /* Characteristic: Model number string */
            .uuid = BLE_UUID16_DECLARE(GATT_MODEL_NUMBER_UUID),
            .access_cb = gatt_svr_chr_access_device_info,
            .flags = BLE_GATT_CHR_F_READ,
        }, {
            0, /* No more characteristics in this service */
        }, }
    },

{
            0, /* No more services */
        },
};
```

### **修改服务属性**
![AB32VG1_ble_Svr.png](https://oss-club.rt-thread.org/uploads/20211204/26749f137f46bd1ebbcd667b9c9ba7ff.png)

这里服务，我们没做修改，保存默认。

### **编译**

编译工程:Ctrl+B，会出错, 如下：
    In file included from <command-line>:
    E:\RT-ThreadWorkspace\AB32_BLE_Demo\rtconfig_preinc.h:8:9: error: no macro name given in #define directive
        8 | #define

双击出错提示，定位到出错的地方，#define后面是空的，删除这个#define即可

### **标题重新编译**

保存修改内容: ctrl+s, 编译:ctrl+b

编译成功

## **调试**

将编译好的，目标文件：rtthread.elf，烧录到中科蓝讯AB32VG1 BLE开发板，操作步骤详细请参阅： [基于RT-Thread的AB32VG1开发环境搭建](http://bbs.sunsili.com/thread-225595-1-1.html)

### **获取BLE设备数据－－制造商信息**

![AB32_BLE_debug_blerd.JPG](https://oss-club.rt-thread.org/uploads/20211204/70d9d58c457af0383cf4e4a020d64e10.jpg.webp)
点"读取"即可,这与我们代码设置一样,说明代码修改正确

### **获取BLE设备数据－－设备型号信息**
点"读取"即可,这与我们代码设置一样,说明代码修改正确

![AB32_BLE_debug_blerdnum.JPG](https://oss-club.rt-thread.org/uploads/20211204/83cd7f0b2c9a45e6b16fb1d804a69593.jpg.webp)

### **读取心率相关数据**

### **心率数据自动数据通知上报**
心律数据是模拟的,开发板硬件上没有
![AB32_BLE_debug_blerdhr01.JPG](https://oss-club.rt-thread.org/uploads/20211204/68b958b70acd9c1c63c48b7d3e6deb20.jpg.webp)

这个数据点代码有BUG,不定什么时候,报错,每次错误还不一样, 这个还得官方分析一下.

## **遗留问题**

1) 定时上报数据点代码有BUG,不定什么时候,报错,每次错误还不一样, 这个还得官方分析一下.
2)现在只有Read(BLE上报数据)功能,没有write(APP->BLE下达数据)功能,这个后面移植一下
3)连接现有通用平台功能, 如微信\涂鸦\天猫精灵.....等等
4)mac_addr是6bytes, 代码里只写了5个数据，这是疏漏还是有意为之
5)制造名长度限制了,没有找到哪里限制了,是不是上报告数据长度限制了,在代码哪里呢

上面遗留问题,还请专家帮忙解决一下,我能力有限.

## **总结**

用RT-Thread基本中科蓝讯AB32VG1 BLE开发快捷方便.做一个只要官方有的驱动及软件,相关方便快捷,没有话自己移植的话,还是比较复杂.
