Can't get OP I2C app to recognize MPU9250
#1
I'm a novice OP user experimenting with a Raspberry Pi 4, having been inspired by the "OpenPlotter Instruction Video for Raspberry Pi" on YouTube.
Using the most recent (2020-03-24) OP "Starting" NOOBS image, I've successfully connected a GSTAR IV GPS via UPS, and attached a Wingoneer GY-81 board containing an MPU9850 and BMP280 to the RP I/O ports.

When I run the OpenPlotter I2C app, it detects the BMP280 at address 0x76, but not the MPU9850.

If I run i2cdetect -y 1, it detects the BMP280 address (0x76), and also an additional address 0x68, which I assume is the MPU9850.

There doesn't seem to be any way to manually configure the MPU9850 in the OpenPlotter I2C app, so I don't know how I can get the information from this chip into Signal K.

Thanks in advance to anyone who can assist.
