dnsmasq in border router error

[Edward]

I'm trying the example border router using 2 x nRF52840 boards one with CLI and the other with NCP connected to a PI. I can get ipv6 addresses and get them to ping each other but can't get a 2001 ip address (no internet connectivity). Looking at the system log for Openwrt I see the router fails to start the dnsmasq service with the error 'failed to create listening socket for port 53: Address in use'. So there is a conflict on port 53 between bind named which has already started and dnsmasq. How do I fix this?

Hi Edward,

Thank you for your interest in the Thread Border Router. The error you see does not influence the behavior of the Border Router itself. Something else must be causing the connection issues you experienced.

Please let me know if you work with the latest version of the SDK and the BR image www.nordicsemi.com/.../nRF5-SDK-for-Thread which are 0.10.0 and 0.10.0-1.alpha respectively.

Do you connect the Raspberry to the Local network via Wi-Fi or wired connection?

I see that you do not get a native IPv6 address. What about the IPv4? Did you follow the Thread Border Router chapter in our documentation? Were you able to ping the Google DNS using IPv4? (ping fd00:0064:0123:4567::0808:0808)

Sorry for posting so many questions. The case is that we need a more information to solve the issue.

Kind Regards, Piotr Szkotak
