Question

代码段：

#define ATT_UUID_SIZE                    16

#define ATT_BT_UUID_SIZE                 2

typedef unsigned char   uint8;

typedef struct
{
  uint8 len;                 //!< Length of UUID (2 or 16)
  uint8 uuid[ATT_UUID_SIZE]; //!< 16 or 128 bit UUID
} attAttrType_t; 

typedef struct
{
  uint16 startHandle; 
  uint16 endHandle;   
  attAttrType_t type; 
} attReadByTypeReq_t;

attReadByTypeReq_t req;
req.startHandle=svcStartHdl;
req.endHandle=svcEndHdl;
req.type.len=ATT_BT_UUID_SIZE;
req.type.uuid[ATT_BT_UUID_SIZE]={0xAD,0x2B};

=＆GT;它说错误＃29当我分配0xAD和0x2B作为uuid我可能做错了什么？

Answer 1

req.type.uuid[ATT_BT_UUID_SIZE]={0xAD,0x2B};

此行不正确。 uuid [xxx]的uuid是一个数组地址，不能通过'='方法赋值。这样做：

req.type.uuid[0] = 0xAD; 
req.type.uuid[1] = 0x2B;

或者像这样：

memcpy(req.type.uuid, YOUR_VALUE, ATT_BT_UUID_SIZE);

错误＃29期望C中的表达式
