RAK 2287 + PI Errors running forwarder

[fuzemobi]

Hi, I'm struggling to get my default pi version working either from your image download or from this repo. The json configs don't appear to be parsing correctly. Is it possible that the locale and/or the device selection are incorrect?

Hardware: Raspberry Pi 4 + Rak2287 + Pi Hat Image: Latest Raspberry Pi OS Lite (32-bit) Released 2022-04-04

On install, the model selection was:

• 7.RAK7248(SPI) no LTE (RAK2287(SPI) + raspberry pi)

After following all steps in the readme, I can't seem to get the forwarder to run. A couple of errors that stand out:

did you setup the pi correctly?

from memory there is some stuff to do in sudo raspi-config the likes of enabling SPI and such

[fuzemobi]

I have included the configuration files for the rak and a picture of the setup. All of the instructions from the RAK setup/github page have been set including the raspi-config settings.

The main question I have is the selection of the rak model when running ./install.sh from the ~/rak_common_for_gateway/install.sh For this build I have tried several settings 7.RAK7248(SPI) no LTE (RAK2287(SPI) + raspberry pi) as well as 9.RAK2287(USB).

Hi @fuzemobi , your should select 9.RAK2287(USB). If you use pi-hat connect RAK2287(USB), after connect pi-hat to pi, you also need a micro usb cable to connect pi-hat to usb of pi.
