cc2540 BTOOL 可以收到notification，但是手机收不到

uint16 sendToCentral(uint8* buff, uint16 len)
{

  //ensure queue of notification is successful
  bool send_error = FALSE;
  //return value to update tail and send ack to msp
  uint16 bytes_sent = 0;
 
  attHandleValueNoti_t noti;
  //dummy handle

  noti.handle = 0x2E;
  //counter
  uint8 i;
 
  while ((bytes_sent < len) && (send_error == FALSE))
  { 
   
    noti.len = min(len - bytes_sent, 20);
    noti.pValue = (uint8 *)GATT_bm_alloc( 0, ATT_HANDLE_VALUE_NOTI,
                                        noti.len, &len );
   if ( noti.pValue != NULL )
   {
      for (i = 0; i < noti.len; i++)
      {
        noti.pValue[i] = buff[bytes_sent + i];
      }
      //connection handle currently hardcoded
      if (!(GATT_Notification(0, &noti, FALSE))) //if sucessful
      {
        bytes_sent += noti.len;
      }
      else
      {
        send_error = TRUE;
        GATT_bm_free( (gattMsg_t *)&noti, ATT_HANDLE_VALUE_NOTI );
      }
    }
  }
  return bytes_sent;
}

然后用手机连接测试， 无法收到notification， 但是一台Android 5.1的平板和BTool可以收到notification， 不知道什么原因，有人遇到过么

这个是BTool 收到的，可是手机怎么也收不到
