如何创建一个服务使用16位UUID

你好,

可以使用相同的数据结构定义16位UUID服务。使用"struct attm_desc_128"的原因是允许相同的数据结构同时覆盖16位和128位UUID元素。仔细查看CUSTOM1数据库的声明，您可以看到服务声明为16位UUID, LED状态特征声明为128位UUID。这个数据库混合包含16位和128位的UUID元素。您可以将此作为参考来创建自己的自定义配置文件。

///属性描述(用于创建数据库)
struct attm_desc_128
｛
///元素UUID.
uint8_t * uuid;// <<<<< uuid数组
/ / / UUID的大小
uint8_t uuid_size;// <<<<<用于定义uuid长度，(ATT_UUID_128_LEN或ATT_UUID_16_LEN)

uint16_t烫;
///元素的最大长度
att_size_t max_length;
///元素的当前长度
att_size_t长度;
///元素值数组
uint8_t *值;

问候，

嗨,对话框的工程师,

只是一个小问题，发送ADC1到应用程序(信标)，哪个参数我可以修改。

我正在从ADC读取温度，希望通过这个ADC服务在app(信标)上显示它。

嗨anghockleong50,

请查看一下SDk5.0.4的ble_app_peripheral示例，以及ADC值1特性是如何定义的。您应该遵循类似的实现。通过通知发送测量的ADC值的函数是app_adcval1_timer_cb_handler()回调。

谢谢,PM_Dialog
