Hi there
I’ve recently purchased a RAK2013 Cellular WisLink Raspberry Pi-HAT BG96 for my Raspberry Pi 3 Model B+.
I’ve loaded the latest raspbian onto my device and ensured that I have updated any outstanding patches. Everything there seems be be working as it should.
The problem is that the pi is not detecting the WisLink at all. I can not see any reference to it at boot time. See the output from dmesg below. Any thoughts would be greatly appreciated
