Tried another device with serial number:
{
manufacturer: 'FTDI',
serialNumber: 'A50285BI',
pnpId: 'usb-FTDI_FT232R_USB_UART_A50285BI-if00-port0',
locationId: undefined,
vendorId: '0403',
productId: '6001',
path: '/dev/ttyUSB0'
}
It is still not visible to my application.

I was under the impression, that my application would work without any change once serial device is connected to my snap. What am I missing here?
I can connect both devices as well:
serial-port internethandel-electron-cme:serial-port :ft232rusbuart manual
serial-port internethandel-electron-cme:serial-port :usb20-serial manual
But I don’t see any of them from within application. Is there any way to debug this?
It seems to work actually, the serialport library is just unable to list serial devices. Most likely because usedadm is missing.
assuming that was a typo and you mean udevadm, you can just add udev to your stage-packages: to ship it in your snap …
@radomirpolach ping, what’s the status of this request? were you able to list serial devices?
@radomirpolach - ping, this request cannot proceed without the requested information?
@radomirpolach - since we’ve not heard back from you, we are removing this request from our review queue. When you have more time to respond, simply do so here and we can add the request back to the queue. Thanks
