I want to connect my RAK2247 to the SPI6 port of my Raspberry Pi 4 (witch has 6 SPI ports) using ChirpStack for example. Is there a solution to configure this choise of SPI, In which file in ChirpStack directory for example should I access to change this configuration?
I know that SPI is composed of MISO, MOSI, CLK and CS but I am trying to choose the SPI6 (GPIO’s : 18, 19, 20 and 21) to communicate with my RAK2247 LoRaWan Getaway.
Setup: Raspberry Pi 4
How to configure RAK2247 hardware SPI connection to the SPI6 of the Raspberry Pi 4 (change SPI GPIO’s for ChirpStack server).
