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
Please see log below:
