Automating nRF91 TLS credential management via serial port AT commands/guides/cellular-iot-guides/b/software-and-protocols/posts/automating-nrf91-tls-credential-management-via-serial-port-at-commandsI have spent a bit of time recently experimenting with different TLS credential configurations using nRF91-DKs. Eventually I got to the point where I wanted to do things like swap out the certificates on a DK for different types or connect several DKen-USTelligent Community 13RE: Automating nRF91 TLS credential management via serial port AT commandshttps://devzone.nordicsemi.com/guides/cellular-iot-guides/b/software-and-protocols/posts/automating-nrf91-tls-credential-management-via-serial-port-at-commandsTue, 14 Jan 2020 16:45:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:be5e769a-8096-44ca-8ae9-05089deb3d3cJVantol2<p>This is great! I would have had to build something similar myself eventually, so it&#39;s great that you shared this. Regarding the method of finding the correct serial port. From PySerial you can use the serial.tools.list_ports method to find all the ports. It identifies them by Vendor ID, VID, PID, Serial Number, and a few other useful nuggets of info. You can then (usually) find the correct one to use based on this info.</p><img src="https://devzone.nordicsemi.com/aggbug?PostID=1290&AppID=27&AppType=Weblog&ContentType=0" width="1" height="1">
