i am developing a wired RS485 environmental sensor node for our rooms at home, using the BME680 to measure temperature, humidity, air quality and additional sensor for light intensity and an LED as a night-light.
The prototype is based on a ESP32 and is currently working well. The sensor nodes should later be hidden in flush-mounted boxes and are powered by 24V.
As the esp32doit-devkit-v1 also supports WLAN and Bluetooth, I am wondering, if I could use the Bluetooth and the RS485 connections for future applications in parallel. Possible use cases would be a RS485 to BT relay to control Philips HUE lights or just use the BT to act as a relay in a mesh.
Enabling both interfaces in my code
error: #error Only one forward link driver can be activated
#error Only one forward link driver can be activated
Are these use cases somehow possible?
