#define CHAR_HANDLE_MAX 11这里我改的11
这是我修改后的dsp

这张图可以是我用手机给从机发送后 从机也回复了信息 是可以读写的
app.c中
* @brief BLE Connection complete event handler BLE连接完成事件处理程序
* @param[in] p Pointer point to event parameter buffer.
* @return
*/
int app_le_connection_complete_event_handle(u8 *p)
{
hci_le_connectionCompleteEvt_t *pConnEvt = (hci_le_connectionCompleteEvt_t *)p;
my_connHandle = pConnEvt->connHandle; 这里我获取了句柄
......
}
// 新建设据发送函数
void send_data_to_target(u16 connHandle, u8 data) {
dev_char_info_t* dev_info = dev_char_info_search_by_connhandle(connHandle);
if (dev_info && dev_info->char_handle[10] != 0) {
u8 value = data;
// 使用 Write Without Response (属性支持)
gpio_write(LED_PIN, 1); // 连接时亮
blc_gatt_pushWriteCommand(connHandle, dev_info->char_handle[10], &value, 1);
}
// ble_sts_t status = ble_gatt_pushReadByTyRequest()
}目前就是 连接时没有问题 就是或者句柄特征的存储 和获取有疑问？不知道到底要修改那些地方？ |
