Flashing code to Arduino nano 33 BLE without losing the port COM

[chaima nikolas]

Hello,

I'm trying to flash an example code  from the SDK  onto the Arduino Nano 33 BLE board.

I tried to use the external debugging on an arduino nano 33 ble card but the problem is when I do this operation the arduino nano card lose its port (COM), it will not be detectable by the computer. 

it is possbile to upload the code without losing USB port of my Arduino 33 using SEGGER Embedded Studio.

Thank you in advance for help

unfortunately, I don't think you can mix Arduino with SDK. You'll have to choose one. If you want to keep the Arduino bootloader, you need to use Arduino.  If you want to use SDK, you need JTag.

Thank you for respending..

Well to be clear, I need to send data from Arduino nano 33 BLE (based on nRF52840) to a mobile application via USB.

So, in this case I need to keep the port COM of my card available after uploading the code (using Segger Embedded Studio).

but when I upload my code using SDK, the COM become unavailable.. ! I really need some help

Ok, I think I understand better what you are asking,  The BLE examples does not include the USB CDC.  The USB CDC is a different example.  You need to merge both into one.  The USB CDC examples is in peripherals.
