Problem with SparkfFun nRF52840 Mini and serial port

Hello,

I currently use a SparkFun nRF52840 Mini that I program with the Arduino IDE.

The principle of the system is as follows: I receive different BLE packets, which I then send directly to the serial port for further processing in a graphical interface programmed in C#.

To start from a simple base, I took the bleuart example from Adafruit. I receive the data directly on the Arduino IDE terminal. It also works on Real Term terminal for example. But when I use Termite, or my graphical interface that receives serial data (which is functional, it receives data from other devices), I receive nothing at all!

Typically. When I start the program, the system remains stuck in " while(!Serial); " even if the port is open in Termite.

Have you been able to get the serial port of a example application to work with Termite or with a personal IDE (like me)?

Impossible to do so. Thank you for your help!
