Hi,
However, when I send packet from node A to node C. Node C does not receive anything. But if I send packet from node A to node B, node B can receive that packet. Not sure what happened. The link shown below is the program I used to send packet. Both source and destination are MAC address.

haven't looked at the code but it sounds like you are using the wrong mac addresses ? Do you use the respective bat0 mac address as source and destination for your packets ?
