I read on this forum that we need to download certificate on the RC7620 module to be able to establish an HTTPS connection with a server. This means that when the certificate expired , we need to reload the new certificate?
it is not practical for IOT device.
This is correct, you can prepare FTP server or HTTP server for downloading the new cert.
Thanks for your Answer.
We had implemented HTTPS on HL 8548 without the need of downloading certificate.
Do you know why we need to do it on RC7620?
This is a network security concern, the goal is to defend man-in-the-middle attacks.
