I want to use an external barometer and connected to the aircraft’s static ports. I bought the Alinan 4pcs Red 3.3-5V Digital Barometric Pressure Sensor
https://www.amazon.ca/Alinan-Digital-Barometric-Pressure-
Controller/dp/B09XQF7Y5Q/ref=cm_cr_arp_d_product_top?ie=UTF8

Which parameter should I put on the following parameters:

  • baro_ext_bus
  • baro_probe_ext

Thank you

I would try:
BARO_EXT_BUS, -1 (DEFAULT)
BARO_PRIMARY, 1
BARO_PROBE_EXT, 1024 (BMP388) And hope the driver for the 390 is the same.

Note: I see these come with a BMP280 also. Your link doesn’t work so not sure which one you have.
