The Radio expose an api that can be queried by web or using following python api https://github.com/tiwilliam/fsapi/blob/master/REVERSE.md

by downloading the firmware (in this case I'm still testing the one from the github developer tiwilliam) http://upload.wifiradiofrontier.com/updates/ir-mmi-FS2026-0500-0052.2.9.10.EX63406-3RC2.isu.bin?c=ir-mmi-FS2026-0500-0052&m=1122334455&v=2.6.17.EX53300-2RC3&t=Cust-File&n=2.9.10.EX63406-3RC2

binwalk ir-mmi-FS2026-0500-0052.2.9.10.EX63406-3RC2.isu.bin -e -X -M -B -A

By doing so I'm able to unpack some file

there should be a Marvell sd8782 sdio as is present into the firmware a sd8782_uapsta.bin file
