RM3100 compatibility issue

[cramredan1]

Hi. I'm experiencing problems getting RM3100 magnetometers/compass detected by iNAV 8.0 on a Kakute H7 V1.3 flight controller (link to Holybro), be it through Serial (under MSP protocol) or I2C operated.

MATEKSYS CAN-L4-3100 should be detected in UART Serial/MSP mode (link to Mateksys) but is definitely ignored in iNAV 8.0

DROTEK RM3100 should be detected in I2C mode (link to Drotek) but is also ignored in iNAV 8.0

Has anyone on this forum achieved connecting one of these two magnetometer/compass boards on his FC??
Any sugestion allowing me to use this excellent sensor would be more than welcome.

In the targets folder, I only examples of it being used via SPI, and I can't find any reference to its I2C address. So it is possible I2C mode is not supported by inav.

Confirmed, INAV code expects RM3100 on SPI bus.

Thank you so much for your "express" reply Marcelo. Even if that does not solve my problem, at least things are now clear to me and without ambiguity. Next step: purchase of an SPI compatible flight controller... (rather than redeveloping the wheel). Have an excellent day from Paris.
