NBSSLWebClient not working

patrickm · May 20, 2022, 4:39pm

I have been trying to get my NB 1500 working. So far I have updated my firmware to the latest release (ATI9 returns L9.9.00.00.05.12,A.02.21), and gotten SMS functionality, and the NBWebClient works. I am using a sim from a hologram in the U.S.

But when I try the SSL client (connecting to https://www.arduino.cc/asciilogo.txt) it returns a webpage that says "Moved Permanently" instead of what you see if you put that link in a browser.

The only change I made to the sketch was to add hologram as the APN in nbAccess.begin().

Can anyone help me understand what is going on here?
