IMU not detected - GY-91 sensor module (BMP-280 & MPU9250)

[baltika_no_9]

Well this is probably of no use to you but let me try. I have a gy-91 and it works fine.

Pi4 4GB, OPv3 64bit, all latest updates.

I connect the gy-91 (powering the 3.3V pin from 3.3V on the pi)

I run some tests to check that the pi can see both BMP280 and the IMU and that works fine

i2cdetect -y 1 shows the correct addresses - 68 (MPU), 76 (BMP280)

Start Pypilot (v3.2.13), and it shows Detected IMU-925x

I select IMU only

Approve the access request and give read/write permissions

In Pypilot I seem to need to click IMU only again but after that the data appears in Signal K

I can calibrate the device in Pypilot without issue.

I know there have been issues with some gy-91s but my experience is different.

I'd be happy to send one of you my gy-91 to try if you like.

Note I am connecting directly to the pi, not via a PICAN hat.
