RAK3172 serial print string of old code


Hello community,
My Monitor Serial window prints out some strange strings, it’s strings of old code, but I’ve uploaded the new code and no longer has anything to do with the old code or commands that print out similar strings.
I’ve done so many new code loads and this still happens.
Have you come across this situation?
Thank you.

Can you share your code please? @Nam

Hello Nam,

The Current Work Mode: nnnnn message is coming from the RUI3 API low level and are not from old code.
This will be always showing together with :EVT=mmmmm messages on a join success or after a packet transmission.

However it seems you are sending something on the terminal connection that is not a valid AT cvommand.
