An error occurs in [Serial emurator] in the [Validation] tab of NANOEDGE AI STUDIO

[hashimoto_m]

When I select the library in the [Validation] tab of NANOEDGE AI STUDIO and run [Serial emurator], I get the error message "No data are being received. Please ensure the correct COM port is selected."
However, I am able to obtain data if I select the same COM port using TeraTerm (terminal emulator).
Incidentally, the same error occurs whether the baud rate is 9600 or 115200.
The board I am using is B-L475E-IOT01A2.
Does anyone have any information on the cause of this?

Hello @hashimoto_m,

try to close every app that may use the COM port and retry.

Can you share the logs please?

NanoEdge AI Studio may sometimes fail to release and reconnect to the COM port. You can close and reopen NanoEdge AI Studio. Then reconnect the B-L475E-IOT01A2.

Hello @liaifat85,

Thanks for the comment, it is interesting to know.

For your information, everything related to serial is being redone for the next update.

Do not hesitate to tell us if you see strange behavior like that in this current version or in the next ones

Have a good day

Julian
