I am making an application using nrf52840 USB dongle.
I am using a python program with pyserial. This works great.
My only problem is that I want to have a very reliable way to identify the correct USB device.
I am using this code in python to identify the USB device.
def find_nrf_com_port():
ports = serial.tools.list_ports.comports()
print("dY"? Available COM ports:")
for port in ports:
print(port)
for port in ports:
if "Nestlab" in port.description or "USB Serial Device" in port.description:
return port.device
return None
this is returning
PS C:\Users\BjornOlsen\Documents\GitHub\nestlab_usb_stick\usb_comm> python3 .\read_serial.py 🔍 Available COM ports: COM17 - USB Serial Device (COM17) ✅ Auto-detected COM port: COM17 Connected to COM17...
The problem here is that the device is called "USB Serial Device". Not a very descriptive name!
In my nrf52840 I am using this prj.conf.
CONFIG_GPIO=y CONFIG_USB_DEVICE_STACK=y CONFIG_USB_DEVICE_PRODUCT="Nestlab USB Stick" CONFIG_USB_DEVICE_MANUFACTURER="Malsen Medical" CONFIG_USB_DEVICE_SN="0001" CONFIG_USB_CDC_ACM=y CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=y CONFIG_SERIAL=y CONFIG_CONSOLE=y CONFIG_UART_CONSOLE=y CONFIG_CJSON_LIB=y
I was expecting that this would change the name to "Nestlab USB Stick" - but alas this does not work.
Note! I do not need it to show up in windows. I only really need the name to be unique when I list USB devices using pyserial.
