Why does my screen turn grey when attempting to pair a Bluetooth device?

This is perfectly normal behavior. The infotainment system will block and wait for you to connect your smartphone before any normal operations continue.

The infotainment system will become responsive again after 10 seconds, regardless of whether a Bluetooth device is connected or not.

Why are some segments of dashcam footage corrupt on system sleep/shutoff?

The current segment of dashcam footage may be corrupted if Axolotl is running and the system enters standby mode (negotiation with the dashcam logger does not occur on deep sleep, as these are fundamentally different subsystems).

Note: There is work in progress to integrate the deep sleep watcher into the main UI thread, allowing for sleep mode to toggle the data logging system off. Until then, make sure to exit Axolotl correctly by tapping on the red X.

Why am I unable to get a fix with the GPS chip?

You're likely running on L4T R28.1, which requires the use of an experimental driver to enumerate the GPS chip. Upgrading to L4T R28.2 should solve this problem.

Otherwise:

• Check your GPS chip's connection, and make sure your antenna is properly connected and unobstructed.
• Manually re-install the GPS chip's driver. To do this, navigate to source/navigation/acm and run sudo ./installCDCACM.sh. Manually reboot the Jetson with sudo reboot.

Why is my dashcam footage corrupt (or what if it contains no playable streams)?

The Raspberry Pi camera controllers may have booted before the Jetson and were unable to connect to the Jetson's AP network to broadcast their stream.

Cycling the power of the Raspberry Pis while the Jetson is on should alleviate the problem.

Where is my master_log.csv?

A master data log with all AHRS data associated with the appropriate OBD time slots will only be assembled upon exiting Axolotl.

Please close Axolotl using the X button and do not attempt process kill from the command line by the kill command or otherwise.

Why are OBD logs not being produced even with a Bluetooth dongle connected?

The OBD2 dongle may not be paired and connected correctly. Please try the connection using third-party OBD2 software (OBD Auto Doctor is a good one).

If the problem persists, please contact us or submit an issue.

Why do I not have an RDS option on the FM menu?

You may not have configured GQRX correctly.

You can reconfigure GQRX from scratch by first deleting the GQRX configuration file by executing rm -f /home/nvidia/.config/gqrx/default.conf from the terminal.

Then, run GQRX on its own from the Ubuntu applications drawer. Once the antenna has been configured, navigate to the View menu and check RDS. Quit GQRX; settings should be saved for GQRX in Axolotl.
