HL7800 HTTP DNS Error

Hi There,

I am attempting to do a simple HTTP connection to www.google.com with an HL7800, but I recieve a DNS error when I try do so.

In general, I have been finding the documentation on the HL7800 to be quite lacking. There are no “how-to” sections for HTTP and HTTPS in the appendix of the AT command guide like some of the other modules have.

Can anyone see where I am going wrong? With the “at+CGCONTRDP” command at the end of the log, you will notice that no DNS addresses are reported back. Perhaps this is a service provider issue?

I do have the latest firmware on the module: HL7800.4.3.9.0

Hi @matthew,
From the result

at+CGCONTRDP
+CGCONTRDP: 1,5,“attach.telus.com.mnc760.mcc302.gprs”,25.250.66.149.255.255.255.252,25.250.66.150, OK

It looks like DNS was not provisioned. Since we cannot connect to Telus network so I try on our network and It works fine. I recommend that you contact operator admin or distributor for more support
