Hello,
I have a working setup with a Raspberry Pi 4B, a Moitessier Hat (version 1) and a few additional I2C sensors. Now I want to add a second remote MPU-9259 sensor on the I2C bus. The reason is simply to have a possibility to place this second IMU in less EM-noisy place on the boat. The MPU-9250 on the Moitessier Hat uses the I2C address 0x68 and the remote one uses 0x69. If I connect only one IMU at the time, the pypilot output to Signal K is fine meaning it reads the data from the IMU from either one or the other address. But when I connect both IMU, pypilot reads only from the Moitessier IMU (0x68) and it ignores the second remote IMU on address 0x69. Apparently, the pypolite is configured such that it searches first 0x68 and if there is nothing it skips to 0x69. Now my question: is there a way to temporarily disable the IMU on the Moitessier hat respectively force pypilot to read only from 0x69? An onther option could be to change the address on the Moitessier hat, but I do not know how. Any idea or hint is welcome.
