nRF9160 Ethernet and LTE both available but cannot open sockets under Ethernet

[Taylor]

I've got an nRF 9160-dk board I have been able to connect over the LTE using TLS to my own data repository site and to google.com and example.com

What I've not been able to do is get a connection over the Ethernet to anything.

So far I've tried:

• using CONFIG_NET_SOCKETS_OFFLOAD=n which results in me getting EPROTOTYPE (-107) when trying to open the socket
• enabling CONFIG_MBEDTLS=y and CONFIG_MBEDTLS_TLS_LIBRARY=y this did not change anything
• Setting CONFIG_DNS_RESOLVER=y and CONFIG_DNS_SERVER1="1.1.1.1"
• I've also tried connection without TLS

Additional notes;

I have verified that I can run the DHCPv4 client code and get an address and the gateway route. I'm also able to use getaddrinfo to get the DNS address of my site with CONFIG_NET_SOCKETS_OFFLOAD=n set.

Hi,

Could you provide more information about your setup?

Could you elaborate on what you try to achieve? 

Best regards,

I'm trying to make it where we can use Ethernet or LTE-M to upload data over https. I've taken a snapshot of the code and put it on Github: https://github.com/zeitue/lte-and-ethernet

Hi,

Could you show your setup? How are your devices connected?

What I've not been able to do is get a connection over the Ethernet to anything.

What have you tested? What are the results? 

which results in me getting EPROTOTYPE (-107)

Could you show the full application log which contains this error?

Best regards,
Dejan

I seem to have broken my code more when I was trying to get this information, I'll reply once I get the new issues resolved.

Hi,

OK. You can get back when your other code issues get resolved.

Best regards,
