velvet iris
App version 12.0-beta (eeed7343)
Firmware 4.5.2 flashed on the FC: HBRD/HUMMINGBIRD_FC305(STM32F7X2), Version: 0
I've been troubleshooting a Lumenier NDAA RID module with GPS (UBLOX SAM-M10Q) and Magnetometer (LIS3MDL) . FC also has an integrated barometer (DPS310), shows up as the only connected I2C device, no I2C errors in status inside CLI.
-Magnetometer wires from the module are soldered to SCL/SDA on FC accordingly.
-GPS, Mag are enabled in configuration. GPS works normally, but magnetometer shows not Detected or Disabled" in setup Tab.
-In Sensors, Magnetometer checkbox is visible, but unchecked and grey'ed out in sensor tab, unable to check it to view any data.
-Unplugging the module while disconnected and reconnecting does not change the connected I2C device count.
-Addressed Mag to 0x1E in CLI (as listed on Lumenier's product page).

No battery connected, RID is powered off 4v5 pin on FC, so it powers up with USB connected and no lipo. GPS is soldered to UART5 TX/RX pins on FC.
Does this have a fix in any other versions of betaflight other than 4.5.2?
Thanks in advance, looking forward to figuring out what the issue is, in case anyone else has experienced this.
