[IoT SDK] PC can ping but CoAP Client can't work with PCA10028!

[SlimaneChen]

Hello everyone:

i'm testing the iot SDK 8.0, but got some problem with that. Using the CoAP observable server example with it.

env: pca10028 + ble dongle + raspberry pi b+ + router + pc

My raspberry and pc both can ping pca10028 with global ipv6 by follow this page.

But when i'm using Firefox Copper plug-in as CoAP client it can not work. I use wireshark to get the package message and it shows "Destination Unreachable(Port unreachable)"

Following is my setting.

And this is how i ping from pc.

And this is the wireshark's message for the problem.

what do i need to do to solve this problem, hope can get help from you all

thanks so much!

Hey everyone I solved the problem and wanna share with you all. As I mentioned i want to use PC as my CoAP Client.

So later when i check the routing table i found the problem.

When i used ip -6 route, it doesn't show any information about route from eth0 to bt0.

Than i used ip -6 route add 2005:1/64 dev bt0 to add the route to bt0

than it works, so maybe next time u have some problem like this, u can try my way. thanks everyone
