How to connect MPU9250

[yiannis]

ok, there is no data from your IC-sensor, only the IC Adress is recognized by i2c scanning.
The Problem is now somewhere in the PiPilot Plugin or your sensor.

my pipilot plugin (without pilot HAT) shows this:


so your sensor is not recognized. sorry for this. 
if you have spare esp8266 available you could burn tasmota on it and try your sensor on this system to check if it is defective. 

but for now i would try another of these cheap sensors from another brand.

eventually you may dig into the hardware requirements of the pipilot plugin software on github to find if your sensor chip (printed on the ic) is supported. Maybe it is simply defective or faked (but i don´t believe this).

PS: about the SK data (all zeros) - the OP-plugin makes automatically an path to SK, even if it is not filled with correct data ;-)

Hi Holger,

Thanks for your help. I was suspecting incompatible or defective IMU, so you have somehow confirmed my suspicions. I have put an order for some inexpensive ones just to experiment on my "bench".

If I find a cheap one that does the job relatively OK, I will use it on the boat. If not, I will se what I will do.

I will update when I have more results; at least now I know what I am looking for.

Thanks for your time,
Yiannis
