MPU-9250 not detected

[seandepagnier]

Can you simply run the pypilot_boatimu script from the console?

It should give an output showing the sensor or better error message. Ensure pypilot and no other service accessing the device is run. It should work on either 0x68 or 0x69

It appears that my MPU9250 is detected. However, I'm facing other issues. Something about "bind failed" and "failed to read IMU" doesn't look to be too good. Running i2cdetect -y1 returns a result at 68. Shouldn't I also be seeing another? I'm concerned that I might be one of those poor saps who reveived an incomplete module .

I hope that somebody might be able to decipher the following and perhaps lead me down the road to a successful install...

Code:

I'm runing pypilot 3.2.11 with OpenPlotter 3.5.0 on a Pi 4b

Yet I do see 2 data sources from Pypilot in SignalK:

• navigation.attitude (populated)
  

• navigation.headingTrue (also populated)

I'm not familiar with OpenPlotter but "bind failed" might indicate that you're launching two instances of pypilot, which could explain why the second one is not able to access the MPU.

also me I have a smimilar issue wth bind failed...

Failed to open SPI bus 0, select 0
Using fusion algorithm Kalman STATE4
BŁĄD: Nie wykryto IMU 378.787526965
pypilot_server: wiązanie nie powiodło się; masz już serwer?

if I go to Web control I see details for IMU. Wondering if Web control doesnt disturb here?

Ps.

not actual, I solved the issue
