I followed this tutorial Thread Border Router using Linux + KW as Host Controlled Device with Serial TAP for DHCPv6-PD to create a complete Border Router with my Raspberry PI + Host Controlled Device with Serial TAP.
At this point I am perfectly able to communicate to my nodes when I make coap messages from my RP. However, I want to receive the multicast POST message that my Thread nodes send.
When I make a multicast POST request from a node, I am able to see the message sent in every node from my Thread network, but I am not able to see it from the Thread_Shell program of my host controlled device + RP with TAP.
There is any way to obtain the multicast POST message in my Border Router configured with serial TAP?
