ok.
Dmesg had some detail of the module being loaded. This is much the same as appears in
Fedora.

Can I glean anything from Armbian that might help me get r8723bs working in Fedora?
The file rtlwifi/rtl8723bs_nic.bin is present in my Fedora 32 Arm.
That they have non upstreamed patches, and by the look of the kernel
naming a forked kernel that's 10 releases out of date of the 5.4
stable series and likely has security CVEs?
