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

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
注意选择最新SDK 1.1.0

配置工程操

配置详情如下：

开启：
宏:
宏:
宏: （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：
http://bbs.sunsili.com/data/attachment/forum/202112/04/173233i6qy6yq6khhucbny.jpg
修改mac_addr
工程目录下：
packages\bluetrum_sdk-latest\bluetrum_nimble\porting\npl\rtthread\src\ble_platform.c
http://bbs.sunsili.com/data/attachment/forum/202112/04/173233thfnl4nl4zdzhizy.jpg
我修改如下:
[*]void bt_get_local_bd_addr(uint8_t *addr){ uint8_t addr_table = {0x41, 0x42, 0x18, 0x58, 0x68, 0x88};//mac_addr是6bytes, SDK代码里只写了
复制代码
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
http://bbs.sunsili.com/data/attachment/forum/202112/04/173233xuv4je42hjpevylh.jpg
我修改如下:
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：
packagesbluetrum_sdk-latestbluetrum_nimbleappsblehrsrc
http://bbs.sunsili.com/data/attachment/forum/202112/04/173233w3w5syzwddyzy3rk.jpg
我修改如下:
[*]static const char *manuf_name = "谷动谷力";//Sunshine Silicon";//可以中文得长度长了,上报不了数据
[*]static const char *model_num = "SunSilicon HR Sensor";
[*]uint16_t hrs_hrm_handle;
[*]
[*]static int gatt_svr_chr_access_heart_rate(uint16_t conn_handle, uint16_t attr_handle,
[*] struct ble_gatt_access_ctxt *ctxt, void *arg);
[*]
[*]static int gatt_svr_chr_access_device_info(uint16_t conn_handle, uint16_t attr_handle,
[*] struct ble_gatt_access_ctxt *ctxt, void *arg);
[*]
[*]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 */
[*] },
[*]};
复制代码
修改服务属性

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：

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

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**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.
