Hi,
I'm using the nRF9160-DK and I need to implement an external uart communication.
Which GPIO can be configured and are available on the various connector?
I have checked the schematic but is unclear which GPIOs are free. Can uart be used without the need of the companion nRF52?
I have tried to modify the overlay file but after this configuration is there any other configuration that must be done?
BTW, can the uart be enable on all the GPIOs or there are specific ports that I must use? (the datasheet is very unclear about this point)
Thank you :)
