【Nucleo+BLUENRG心得】+BLUENRG 控制小车详解31、BLE信息
SBBLEController
提供了Service UUID  和 Characteristic UUID  同时支持不同的BLE设备


(3) RCB default typoe peripherals
Service UUID: 0xFFF0
Characteristic UUID: 0xFFF1

2、数据协议信息
The 1 - 2nd byte: Button
(Right buttons)
　UP: 0x0001
　DOWN: 0x0002
　RIGHT: 0x0004
　LEFT: 0x0008
(Left buttons)
　Y button: 0x0010
　A button: 0x0020
　B button: 0x0040
　X button: 0x0100
　left center: 0x0080
(Shift buttons)
　L1: 0x0200
　L2: 0x0400
　R1: 0x0800
　R2: 0x1000
(Other)
　START: 0x0003
　SELECT: 0x000C

The 3 - 4th byte: Left analog Stick
　Left - Right: 1-255 (Neutral=128)
　Up - Down: 1-255 (Neutral=128)

The 5 - 6th byte: Right analog Stick
　Left - Right: 1-255 (Neutral=128)
　Up - Down: 1-255 (Neutral=128)

The 7 - 9th byte: Accelerator
　X axis: 1-255 (Neutral=128)
　Y axis: 1-255 (Neutral=128)
　Z axis: 1-255 (Neutral=128)

The 10th byte: Status information

3、BLUENRG 程序 增加 Service UUID: 0xFFF0


const uint8_t service_uuid[2]  = {0xF0,0xFF};         //service

//添加SERVICE
  ret = aci_gatt_add_serv(UUID_TYPE_16, service_uuid, PRIMARY_SERVICE, 10, &sampleServHandle); /* original is 9?? */
  if (ret != BLE_STATUS_SUCCESS) goto fail;   

aci_gatt_add_serv函数修改部分
a:UUID类型选择16位
b:service_type         
c:max_attr_records  这点很重要，Characteristic 如果越多该参数也要增加

3、BLUENRG 程序 增加 Characteristic UUID: 0xFFF1

const tHalUint8 charUuidTX[2]  = {0xF1,0xFF};          //Characteristic


//1添加一个  Characteristic 服务
        ret =  aci_gatt_add_char(sampleServHandle,  UUID_TYPE_16, charUuidTX, 12, CHAR_PROP_WRITE|CHAR_PROP_WRITE_WITHOUT_RESP, ATTR_PERMISSION_NONE, GATT_SERVER_ATTR_READ_WRITE,//GATT_SERVER_ATTR_WRITE,
                                                                                                        16, 1, &TXCharHandle);
  if (ret != BLE_STATUS_SUCCESS) goto fail;

怎么不能添加多个服务及服务下的特征值
const uint8_t uuid[16] =                  {0x66,0x9a,0x0c,0x20,0x00,0x08,0x96,0x9e,0xe2,0x11,0x9e,0xb1,0xe0,0xf2,0x73,0xd9};
  const uint8_t charUuidTX[16] = {0x66,0x9a,0x0c,0x20,0x00,0x08,0x96,0x9e,0xe2,0x11,0x9e,0xb1,0xe1,0xf2,0x73,0xd9};
  const uint8_t charUuidRX[16] = {0x66,0x9a,0x0c,0x20,0x00,0x08,0x96,0x9e,0xe2,0x11,0x9e,0xb1,0xe2,0xf2,0x73,0xd9};
  const uint8_t charUuidRX1[16] = {0x66,0x9a,0x0c,0x20,0x00,0x08,0x96,0x9e,0xe2,0x11,0x9e,0xb1,0xe3,0xf2,0x73,0xd9};
Osal_MemCpy(&service_uuid.Service_UUID_128, uuid, 16);
  ret = aci_gatt_add_service(UUID_TYPE_128, &service_uuid, PRIMARY_SERVICE, 8, &chatServHandle);
  if (ret != BLE_STATUS_SUCCESS) goto fail;   

  Osal_MemCpy(&char_uuid.Char_UUID_128, charUuidTX, 16);
  ret =  aci_gatt_add_char(chatServHandle, UUID_TYPE_128, &char_uuid, 20, CHAR_PROP_NOTIFY, ATTR_PERMISSION_NONE, 0,
                16, 1, &TXCharHandle);
  if (ret != BLE_STATUS_SUCCESS) goto fail;

  Osal_MemCpy(&char_uuid.Char_UUID_128, charUuidRX, 16);
  ret =  aci_gatt_add_char(chatServHandle, UUID_TYPE_128, &char_uuid, 20, CHAR_PROP_WRITE|CHAR_PROP_WRITE_WITHOUT_RESP, ATTR_PERMISSION_NONE, GATT_NOTIFY_ATTRIBUTE_WRITE,
                16, 1, &RXCharHandle);
  if (ret != BLE_STATUS_SUCCESS) goto fail;

  Osal_MemCpy(&char_uuid.Char_UUID_128, charUuidRX1, 16);
  ret =  aci_gatt_add_char(chatServHandle, UUID_TYPE_128, &char_uuid, 20, CHAR_PROP_WRITE|CHAR_PROP_WRITE_WITHOUT_RESP, ATTR_PERMISSION_NONE, GATT_NOTIFY_ATTRIBUTE_WRITE,
                16, 1, &RXCharHandle1);
  if (ret != BLE_STATUS_SUCCESS) goto fail;


报如下错：BlueNRG-1 BLE Chat Server Application (version: 1.0.0)
Error while adding Chat service.
