| * Quarky Message Format: |

| * The totalMsgLen is the length from Radio till msgBody. The value of Radio |
| * is always defaulted to 0. The MsgLen is the length from msgId till msgBody. |
| * The length of the msgBody varies with respect to the MsgId. Buffer space |
| * for MsgBody is already allocated in the received buffer. So in case of READ |
| * we just need to populate the values in the received message and send it |
