Navio2 + TFMini Plus results in Baro not recognized

Latest Raspian Emlid build - emlid-raspbian-20191128.img.xz
Updated Arducopter to 4.0.3 (same issue on 3.6)

I connected two TFMini Plus to through a splitter on the i2c bus of the Navio2 and this gives me a Barometer error.

The same thing happens when i directly connect just one TFMini Plus.

i2cdetect results:

Any idea’s on how to solve this issue ?

Thanks

Think I’ve found the problem. The TFMini Plus needs to be set to i2c mode using uart

Hi @wvthoog,

Thank you for sharing the solution!
