Original Question: Received packets size by Ramya
Hi
With reference to the posts Data Packets from Node WSN and Restrict End Node from pushing packets continuously. The size of Packets received is 80 bytes, Is their any possibilities to reduce this packets size , say only to the Mac ID and the Accelerometer Measured values.

Hi Ramya,
This option is provided in the AD6LoWPAN02 release supported on EVAL-ADuCM3029 EZ-KIT Hardware, you can edit the code to achieve this on BUNCH board. The “Add_SensData2Payload” function in ADSens-Main.c file adds the sensor data and statistics to the payload buffer. Comment the statistics code part at end of the function after the “SensorMask” addition. This should work.
thanks & regards

Hi Ramya,
The extra data you see other than sensor is statistics. To disable statistics send a “Disable Statistics” command to the Node from the Border Router that should work. Please see the below figure for the information on how to send command to a node. This information is already provided in the Monitoring & Control section of “AD6LoWPAN-All-in-One-GettingStartedGuide_v1.0”.
Note: Ensure to select the correct node address and make sure the node is not in sleep state before sending the command.
Thanks & Regards

Thank you for your reply, when i tried to do the same, the Disable Statistics command was not found.

Hi Ramya,
Please go through the below link for the information on header, the data you are seeing other than MAC address and port is not over the air data, Border Router adds this information and sends it in the format the generic ADWSN-UI tool understands. At present most of it are dummy values, the marked fields in the link are important.
