contiki-os spirit1 with stm32 problems

[obaginski]

Hello,

I'm trying to arrange connection of three devices where one of them is sending data packets to the second, and then second one is forwarding data to the third one. I was following stm32 getting started documentation http://www.st.com/content/ccc/resource/technical/document/user_manual/group0/13/c8/99/6c/b7/38/4d/90/DM00255309/files/DM00255309.pdf/jcr:content/translations/en.DM00255309.pdf I've noticed a few issues:

• in /examples/ipv6/udp-rpl server is getting stuck and not responding after receiving up to 8 packets, data is not forwarded as described in documentation and presence of two server nodes results in not receiving sent data by any of them,
• in /examples/ipv6/simple-udp-rpl data is sent correctly when there is one or more senders and just one receiver but can't be received if there is more than one receiver(by any of them). Also i noticed that switching off one of nodes doesn't make it disappear from the neighbours table.

If anyone came across similar issues or solved this problem, I'd be glad to get some clues or advices.

Best regards,

Oskar

If you're using a recent Nucleo with CAT5 or higher STM32L1 devices, the node_id problem in issue #2305 might have some affect on how a network of nodes communicate with each other. Without a unique ID the nodes may collide in some way.
