请问CH579做蓝牙主机时，怎么读取从机发送的notify呢？
主机无法开启从机notify，会提示"Write Error: 1"，请问应该如何解决呢？
attWriteReq_t req;
req.cmd = 0;
req.sig = 0;
req.handle = GATT_CLIENT_CHAR_CFG_UUID;
req.len = 2;
req.pValue = GATT_bm_alloc(centralConnHandle,ATT_WRITE_REQ,req.len,NULL,0);
if ( req.pValue != NULL )
{
req.pValue[0] = 1;
req.pValue[1] = 0;
if( GATT_WriteCharValue(centralConnHandle,&req,centralTaskId) == SUCCESS )
{
printf("\r\nenable notify\r\n");
}
else
{
GATT_bm_free((gattMsg_t *)&req, ATT_WRITE_REQ);
}
