Have you been tinkering with a I2C or SPI sensor on an MCU like Arduino, ESP32, or Raspberry Pi, and yet it's not available on the PX4 Autopilot? Porting the 3rd party C++ API might not be as daunting as you would think. This talk will walk you through some of the caveat in bringing the Bosch BME688 gas sensor to drone code as related metrics could further be populated and utilized by the PX4 ecosystem such as Nuttx terminal, flight uORB topics, and even companion modules over MAVLink SDK.
