HL7812 static DNS

[hkiol]

Hi,

I want to use static DNS with the HL7812 modem with the latest firmware.

However, this command errors out:

AT+KCNXCFG=1,“GPRS”,“iot.1nce.net”,“”,“”,“IPV4”,“0.0.0.0”,“168.63.129.16”,“8.8.8.8”

+CME ERROR: 932

which indicates that there is some invalid parameter but I can’t find where the issue is.

Can the DNS not be statically configured?

thanks

Same problem in rc76:

Using Custom DNS IP address with RC7620 or RC7620-1

Hello Community, I need some help in understanding whether it is possible to configure the RC7620 or RC7620-1 modem to use a custom DNS IP address instead of the one that is allocated dynamically. So far I have tried the following GPRS connection configurations and they all result in the error +CME ERROR: 932 which means the format of a parameter is invalid: AT+KCNXCFG=1,“GPRS”,“myapn”,“username”,“pswd”,“IPV4V6”,“0.0.0.0”,“8.8.8.8”,“8.8.4.4”,“::”,“::”,“::” AT+KCNXCFG=1,“GPRS”,“myapn”,“usernam…

Btw, will you consider to use udp connection to your cns server for querying the ip address?

I am able to connect to the server using the DNS name but not with the IP.

Does this make sense? What could I possibly do to fix this?

I won’t be using UDP for now.

thanks

what did you see if you use real ip?

[hkiol]

I get ktcp notif: 1,13

13 — SSL connection error

Have you tried not using SSL?

[hkiol]

I haven’t as I don’t have control over that server, but successful connection via SSL and the DNS name is possible… So just by changing from the IP to the DNS, it works.

I guess probably you have input the wrong IP address

you might need to set up another server to test
