I really like the ESP32 and have gotten it to work well as a WiFi access
point and WiFi station at the same time (necessarily on the same channel).
It also has Bluetooth, which I haven't tried, and comes in a
pre-FCC-approved module for $5 or less Q/1. It lets you implement a web
server and thus interface to *everything.*
