Hi, I am currently using EC20 as LTE module to connect my embedded system to the internet.
I have followed some online resources to set up the ppp0 network, and I am able to ping the internet.
For example, it works well when I ping 8.8.8.8 or ping google. com. However, it seems that it could not handle http request since I have tried to reach websites such as http:/ /wtfismyip. com/text with cURL.
$ curl -v http:/ /wtfismyip. com/text
- Trying 95.217.228.176…
- TCP NODELAY set
- Trying 2a01:4f9:4b:4c8f::2…
- TCP NODELAY set
- Immediate connect fail for 2a01:4f9:4b:4c8f::2: Network is unreachable
- Connected to wtfismyip.com (95.217.228.176) port 80 (#0)
GET /text HTTP/1.1
Host: wtfismyip.com
User-Agent: curl/7.58.0
Accept: /
And no response is received.
I am unable to connect to my openVPN network as well. I wonder whether there is extra setting to enable the module to receive high level response. Thank you.
