How To Resolve name / IP number (DNS resolution) through An AT cmd on the Sierra Wireless HL7812 module

IoT Modules Legacy HL Series

Can you please help me find the easiest way to get an IP address by resolving a domain name(for example aws mqtt cloud connection hostname: random.iot.region.amazonaws.com)? Is there an AT command for this? I came across the AT+UDNSRN command from another modem provider, but I couldn’t find an alternative for the HL7812.

FW: HL7812.5.5.14.0

Kind regardss
Thanks.

See if this helps to use udp communication

Thanks, @jyijyi ! Yes, this is exactly what I am using today. I was hoping to find a quick solution on the modem side to bind my offloaded Socket DNS API interface to handle domain name resolution more efficiently. Ideally, I’m looking for an AT command that could resolve a domain to an IP directly on the modem without relying on external processing. Do you know if there’s any built-in functionality for this on the HL7812?

how about using AT+KTCPCFG? after connecting to your server?
