[Babel-users] Intel Edison + Raspberry Pi - Mesh Network

[Christopher Hex]

Hi,

I'm trying to put a number of Intel Edison development boards in a mesh
network using babeld, using a Raspberry Pi 3 as a gateway.
The Intel Edison boards connect fine and routing tables are correctly being
updated.

However on the Raspberry Pi side, the routes are added but they remain
'unreachable'. Further investigation revealed some possible reasons:


   - The multicast messages originating from the Raspberry Pi contain a
   802.1Q (QoS) header, which are not present on multicast packets from the
   Edison boards.
   - The babel logs show that the Raspberry Pi detects messages from the
   Edisons, but the Edisons do only detect some messages from the Raspberry Pi.
   - The RXCOST on the Edison side is INF, and accordingly the TXCOST on
   the Raspberry Pi side is INF.


Any idea on how to solve this issue? Would be great if I could use a babel
mesh network to connect the Intel Edisons through the Raspberry Pi to the
internet.

Kind Regards,

Christopher
