sleepy node (mostly staying in low power, radio not reachable) sending duplicate messages #161

Hi, I think the problem is in contiki, not in coapthon... Maybe you can
check with wireshark the messages actually exchanged, from the logs it
seems everything ok from the coapthon side.

… Hi,
I have a sleepy node running Coap clients(based on Contiki) that sends
data every 5 minutes and stays in low power mode (node not reachable), when
it wakes up, seems like it sends data again and again to the Coapthon
server, there are multiple transactions. That's not good for a node running
on battery. Any idea, why that might be happening? Any pointer will be
helpful, for now, I have no idea where to look.

Hi,
I have a sleepy node running Coap clients(based on Contiki) that sends data every 5 minutes and stays in low power mode (node not reachable), when it wakes up, seems like it sends data again and again to the Coapthon server, there are multiple transactions. That's not good for a node running on battery. Any idea, why that might be happening? Any pointer will be helpful, for now, I have no idea where to look.
Thanks & Regards
