EC20 Response

EC200U response:

Hi @Bean.Wang-Q

AT+CGCONTRDP=1 in EC20 Gives primary and secondary DNS :

36.5.2.0.8.0.0.0.0.0.0.0.0.0.0.17, 36.5.2.0.8.0.0.0.0.0.0.0.0.0.0.17

AT+CGCONTRDP=1 in EC200U-CN doesn’t give DNS, is there a bug in CGCONTRDP cmd ?

23

Please check whether it is registerred.

Hi @Bean.Wang-Q

We have executed AT+CGCONTRDP=1 after establishing pppd connection,

Both on EC20 and EC200U-CN

25

If so you cannot get the EC200U DNS for ipv6.
As mentioned, ppp cannot provide ipv6 dns.

Hi @Bean.Wang-Q ,

is there a bug in EC200U-CN Firmware, ?

EC20 Works fine with IPv6
