RAK7258 TF Card usage?

Hello there,
I would like to use the TF card (sd card) of my RAK7258 for storing the logs to it and maybe to store lora data in case the internet connection is lost.
I inserted an 8 GB TF card, but I can’t find any configuration option on the device web sites and there is nothing automatically stored on the card. The documentation I found as well as the search request in this forum did not show any help :-(.

I am running the newest firmware WisGateOS 1.1.1

Can anybody tell me, how to use the TF card with this device?

Thanks in advance and best regards! :slight_smile:
