【Nucleo+BLUENRG心得】+BLUENRG 通过APP控制 RGB

APP：Multitool
硬件：Nucleo+BLUENRG心

BLUENRG 服务定义：

通过其中一个服务了解它
//添加SERVICE  0XFFF0
  ret = aci_gatt_add_serv(UUID_TYPE_16, service_uuid, PRIMARY_SERVICE, 7+10, &sampleServHandle); /* original is 9?? */
  if (ret != BLE_STATUS_SUCCESS) goto fail;

  //1添加一个  Characteristic 服务 0XFFF1
ret =  aci_gatt_add_char(sampleServHandle,  UUID_TYPE_16, charUuidTX, 1, CHAR_PROP_READ|CHAR_PROP_WRITE|CHAR_PROP_WRITE_WITHOUT_RESP, ATTR_PERMISSION_NONE, GATT_SERVER_ATTR_WRITE,
16, 1, &TXCharHandle);
  if (ret != BLE_STATUS_SUCCESS) goto fail;

//1添加一个特征描述符来服务
//Add a characteristic descriptor to a service
  ret = aci_gatt_add_char_desc(sampleServHandle,
                           TXCharHandle,
                           UUID_TYPE_16,
                           (tHalUint8 *)&charUuidRX4,
                           22,
                           4,
                           (char *)"Rad",
                           ATTR_PERMISSION_NONE,
                           ATTR_ACCESS_READ_ONLY,
                           0,
                           16,
                           1,
                           &descHandle[0]);

其他类推！

接收程序

void Attribute_Modified_CB(tHalUint16 handle, tHalUint8 data_length, tHalUint8 *att_data)
{
uint8 newVal;
  uint8 rgbwVal[LIGHTSPROFILE_RGBW_LEN];

if (handle == TXCharHandle + 1) //11 UUID=0xFFB1  ATT_CHAR_USER_DESC_UUID=Red 接收状态下 //if(att_data[0] == 0x01) notification_enabled = TRUE;
{
receiveData(att_data, data_length);
lvalRed = att_data[0] << 4;
  }
else if(handle == RXCharHandle + 1) //13 UUID=0xFFB2,ATT_CHAR_USER_DESC_UUID=Green
{
receiveData(att_data, data_length);
lvalGreen = att_data[0] << 4;
  }
else if(handle == RXCharHandle1+1 ) //15 UUID=0xFFB3,ATT_CHAR_USER_DESC_UUID=Blue
{
receiveData(att_data, data_length);
lvalBlue = att_data[0] << 4;
}
else if(handle == RXCharHandle2+1) //17 UUID=0xFFB4,ATT_CHAR_USER_DESC_UUID=White
{
receiveData(att_data, data_length);
lvalWhite = att_data[0] << 4;
}
else if(handle == RXCharHandle3+1 ) //19 UUID=0xFFB5,ATT_CHAR_USER_DESC_UUID=RGBW  总开/关
{
receiveData(att_data, data_length);
//BSP_LED_Toggle(LED2);
   lvalRed = att_data[0] << 4;
   lvalGreen = att_data[1] << 4;
   lvalBlue = att_data[2] << 4;
   lvalWhite = att_data[3] << 4;
}

pwmFadeVals();
  pwmUpdateVals();
/* if(HAL_UART_Transmit(&UartHandle, (uint8_t*)att_data, data_length, 5000)!= HAL_OK)
  {
Error_Handler();
  }*/
