I tried to upload the hello world program to the thingy91s nrf9160 via nrf connect programmer app over usb. Unfortunately it didn't work as excpected and the nrf9160 doesn't show up as com ports anymore. I uploaded the blinky example via segger studio over j-link and now the led blinks regularly :) However no com port is visible, the device doesn't show up in the device manager under windows which makes it impossible to receive printk() messages from other examples. How can I fix this issue?
