I’m having trouble interfacing with any of the external devices (ICM20948, MS5611, and HMC5983) on the Here+ V2 RTK module other than the LED controller (TCA62724).
Attached is an example of attempting to write to the ICM20948 (address 0x69) over I2C:
I’ve attempted every possible address that the sensors could be (0x68, 0x69, 0x76, 0x77, 0x3D, 0x3C) and none of them will ACK the read/write requests. Furthermore, when I attempt to read/write to the TCA62724 (via address 0x55) I get a response and can control the LEDs on the module - so I know the I2C connection is, otherwise, working.
Am I missing something? Do I need to bridge a solder joint to access the sensors? I’ve reached out to the PX4 community as well to no avail. Any additional information would be greatly appreciated!
