LG69T(AA) DR not being logged when antenna is disconnected

Hello, i am testing LG69T(AA) EVK. it is getting odometer pulse from vehicle and was able to calibrate. When antenna was unplugged, only the last GPS location was recorded. no DR only data was recorded in the log. my previous testing of L26-ADR i was able to properly record DR navigation only. i am expecting this new chip to work the same.

here are all the versions

is there a newer FW that works better? are there additional configuration commands that can be enabled to understand what is happening in the chip?

Hi @Lev_Beylin ,

The latest fw has been sent to you via private message, please check.
For LG69T-AA, $PSTMDRSENMSG messages are IMU (DR) output. Please check the attached protocol specification.
