Hi everyone,
I am a beginner developing projects with nordic boards and currently am using the NRF9160DK. I just made an application through Ble MCU (nrf52840) and I want to send some data to NRF9160DK to be able to send the data to the NRF cloud. Watching the schematics of the development kit, I saw some common pins named NRF91_IF and NRF52_IF, so I supposed that those pins are used to communicate both MCUs, but I am not clear on how to do that. There is a protocol for that?
Thanks.
