Do I have to use an external SD card?
No, you can just use the internal storage on your device. The external SD card makes sure that you have enough room to store large video files if you are recording video with the onboard camera.
Where does SoloStorm save my log files?
Your logs and videos will be saved to:
- /Android/data/com.petrel.datastorm.activity/files/petrel (SoloStorm)
- /Android/data/com.petrel.circuitstorm/files/petrel (CircuitStorm)
This path is used on both the internal device storage as well as the removable SD card.
The use of this path is required due to Android security restrictions.
Note: Files stored under /Android/data are DELETED when uninstalling the app.
Why is SoloStorm unable to connect to my Wi-Fi camera or data logger?
If your Android device has a cellular radio, it may determine that your Wi-Fi device does not provide internet connectivity and then use only the cellular network for connectivity. To work around this, some devices have a ‘Network Switch’ or ‘Smart Connection’ option under the Wi-Fi settings that you can disable. If your evice does not have such an option, then you can also enable Airplane Mode, and then enable only the Bluetooth and Wi-Fi radios on the device.
Can SoloStorm log data while the phone or tablet screen is turned off?
If you are not recording video using the internal camera, then you may turn off the device screen or use the home button to pause Solostorm and launch another application. The SoloStorm logger will run as a background service. Exiting SoloStorm by tapping the Back button will still shut down the logger.
Why can’t I turn off my device screen while recording video using the internal camera?
Android devices require that a video preview be displayed when using the internal camera.
How can I tell what state the logger is in if it is running as a service?
When the SoloStorm logger runs as a service, a notification appears in your notification bar. The status of this notification indicates the state of the logger. You may also enable voice notifications under SoloStorm’s Display Settings which will notify you when the logger status changes.
How does SoloStorm know when to start and stop logging?
SoloStorm can be configured to start and stop logging based on vehicle speed, or it can be configured to start and stop manually.
If I use an automatic trigger to start logging, will I lose the start of my run before the logger was started?
No, SoloStorm has an internal buffer that captures the start of your run from the moment the vehicle starts to move. Once the start trigger speed is seen, this data will become part of the log.
In manual mode, the start button is used to start both the data logger and the video recorder. In automatic mode, this button only starts the video recorder so that you can capture video between when you launch the car and the logger is triggered by the selected trigger speed.
SoloStorm is not starting the video recorder when staged. Why is this?
If the video recorder was manually stopped (for example, video was accidentally started and the stopped), or you had to stop it while waiting for the course to clear, then the video recorder will not be automatically started again until a run is completed, or the logger is turned off an on.
This is on purpose, so SoloStorm will not continuously start the video recorder if you have manually stopped it while staged.
What is the purpose of the Start, 60ft, and Stop markers?
Only the Staging marker affects logging – the others are used only to better calculate section times and overall run time.
I set up my markers during a course walk, and I changed the session name before racing. My markers have disappeared! How do I get them back?
Markers are specific for each session, and are saved in the session directory where the logs are saved. If you are comfortable with technology, you can manually copy the markers file from one session to another, then start up SoloStorm. Your device should have some type of File Manager app that will allow you to do this.
In automatic trigger mode, SoloStorm starts the video recorder when I am at the staging line, however I did not set a staging marker. Why is this?
If you did not set a staging marker, then after your first run SoloStorm will calculate where the staging line is for the current course, and will start video recording when your are near to it. You can manually stop the video recorder and start it later if you have to wait at the staging line.
My lap times calculated based on Start and Finish markers are not accurate when compared to my posted run times!
The run times that SoloStorm generates will be close, within .2s or so, depending on the accuracy of the markers. For best results, it is important to set all of the markers within as short a delay as possible, as the relative positions can change as GPS drifts. This can happen in the time that it takes to fully walk a course from Start to Finish. Quickly set the Staging, Start, and Finish markers before walking the full course. If you need to, you can precisely set the markers when editing sections in the Analysis view. If you use video and lap time to help set the markers, this can be more precise. NOTE: The relative position of the markets is important as SoloStorm will align your run starts to the Staging Marker in order to compensate for GPS drift. DO NOT set the staging marker anywhere but the actual staging line, or your calculated times will be off.
What cameras are supported?
Petrel Data Apps currently support the following cameras with integrated functionality:
- GoPro Wi-Fi Video Cameras
- Polaroid Cube+ Wi-Fi Video Camera
- Garmin VIRB X/XE/Ultra 30 Wi-Fi Video Cameras (Ultra 30 most recommended)
- On-board Video Camera
Note: if your favorite action camera is not listed here, remember you can always import your video into SoloStorm and CircuitStorm manually to create your overlays for sharing or export the data overlays and merge with your favorite video editor outside of SoloStorm and CircuitStorm
When I calibrate the video recorder, SoloStorm shows me the first frame where my screen flashes a red box. Why do I still need to select a video frame?
SoloStorm will automatically detect the greatest change in red color in the calibration video, and pre-select that frame for you. In case this frame is not correct, you can still select another one.
How can I speed up video overlay processing?
If using Hardware Acceleration for video processing, you are producing overlaid video using the highest quality for your device.
If you would like to disable Hardware Acceleration, you can then decrease the quality of the video overlay. This can decrease the time that it takes to overlay a video, but usually only on the lowest quality setting, and only at low resolutions (480p). Additionally, turning off the logger and any other cpu-intensive applications will speed up this process as well.
Using a good-quality class 10 flash memory card will also help, regardless of the encoding method (accelerated or not).
How do I enable jogging of video frames?
Jogging of video frames during analysis is enabled in SoloStorm’s Video Settings. To jog videos, frames are extracted and saved to the flash storage. This is a more robust method than jogging a H264 video stream in real-time.
Can I preview the viewfinder from my supported Wi-Fi camera?
Not with SoloStorm. If you need to aim your camera, please use the app provided by your camera manufacturer. While video preview can be implemented, it will either consume considerable CPU resources or use your device’s hardware decoders, and neither is acceptable while both logging data and utilizing the internal video recorder on your device.
Which Wi-Fi action cameras does SoloStorm support?
Because there is no standard API for controlling Wi-Fi action cameras, only specific camera models are supported. You can find out which cameras are supported on the SoloStorm product page.
Will you be adding support for my [insert camera brand name here] Wi-Fi camera?
While SoloStorm does support a number of diverse Wi-Fi cameras, only cameras that have a published and supported API from the manufacturer will be supported.
Help, my Wi-Fi camera is not responding to SoloStorm! What to I do?
Sometimes Wi-Fi cameras (especially those manufactured by GoPro) will do odd things such as power on but refuse to power off, or start recording but refuse to stop. These problems occur with the official camera app as well as with SoloStorm, and may be resolved by firmware updates from the camera manufacturer. The only known solution to this problem is to reset the camera by removing then installing the battery.
Downloading video from my Wi-Fi is really slow! What can I do?
If your camera supports the recording additional Low Resolution video files, SoloStorm can download them instead. These videos can be played back on your device, and have their frames extracted for jogging.
I am automatically downloading Low Resolution video from my Wi-Fi camera – can I later download the Full Resolution video for overlaying?
Yes, you can! Simply tap on the Video Widget, and you will be prompted to download the larger video file if you have not done so.
My Wi-Fi camera is only recording very short videos and not capturing the entire run. What’s wrong?
Som Wi-Fi cameras seem to be sensitive to the state of the SD card. When deleting files off of the SD card, you may need to reformat it. If you do not, the camera may stop recording after a short period of time.
How long does it take to download video from my Wi-Fi camera?
For a typical autocross run, it can take up to 30 seconds to download the low-resolution video for analysis. In most cases it will have downloaded by the time you arrive back in grid. High resolution videos can take up to several minutes, however. It is best to import them manually.
I can’t seem to calibrate the internal accelerometer on my device. How do I fix this?
There are a large number of Android devices on the market, and some behave differently with respects to the IMU (accelerometer + gyro). The IMUs on Samsung devices have received the most thorough testing, however if you are having problems please contact support and we can help you gather more information about how your IMU works so we can support your device.
It is recommended that you watch this video on confirming calibration for reference:
Some low-cost, Chinese branded devices have accelerometers that simply do not work (we tested on a Cubot phone), so we suggest that you avoid those if you wish to use the internal sensors.
Enabling ProSolo Race Mode
To enable the ProSolo Race Mode, enter the SoloStorm Settings, and select ‘Display’. You can then select from among the available race modes – Solo2, ProSolo, or Hill Climb.
How does ProSolo Race Mode differ from Solo2?
ProSolo Race Mode adds a 60′ course marker, as well as a Left Side and a Right Side for the current session. Each Course Side contains it’s own set of Course Markers. The currently selected Course Side is rotated between runs (if that option is selected when setting up the Session Name and Driver List). You can manually rotate between sides if you need to, and the current driver can be selected from a pop-up list.
How should I set Markers in ProSolo Race Mode?
Follow the same procedure as with regular Solo2 markers, except you must manually switch the current Course Side and capture markers for each side. It is best to capture the markers for each side in as little time as possible, in order to prevent GPS drift from factoring into the relative positions of the markers. If need be, you can manually set the markers during analysis.
Analyzing on a PC
Can SoloStorm export log data for use with other analysis or overlay software?
Yes, SoloStorm can export log data in CSV format.
Integrating with a RaceCapture / DL1 / VBOX / Other logger
Does calibrating the internal accelerometer affect data from a 3rd party data logger?
The internal accelerometer is not used when SoloStorm is configured to work with a 3rd party logger, so calibration has no effect. The logger must be correctly mounted in the vehicle and configured in order to provide accurate acceleration values.
Are runs recorded using a 3rd party logger different from log files recorded off of a Bluetooth GPS?
No, the log files are structurally the same, and store data in the exact same format.
What data will SoloStorm use from a 3rd party logger?
SoloStorm will use GPS speed, GPS position, GPS accuracy, time, acceleration, gyros (if available), and OBD/CAN channels that you configure (if available).
Do automatic triggers work with a 3rd party logger? Can SoloStorm tell a logger to start logging to it’s own memory card?
Yes, automatic triggers work with a 3rd party logger, but SoloStorm does not tell the logger to start logging. The logger is completely independent of SoloStorm, which uses only the continuous data stream from the logger.
What is the best way to maximize phone battery life while using SoloStorm?
If you are not using the internal video camera, you may turn off your device’s screen.
I am recording video using the internal camera. What now?
Leave your phone plugged in to a USB car charger. If you are charging multiple devices, such as a GoPro camera, invest in a higher-quality, 2A charger such as the Lenmar AIDCU4.
I can’t use a car charger in my race car. What do I do now?
Place your phone into airplane mode, but enable the bluetooth radio. Very few phones support this, so the other option is to pull your sim card and put it somewhere safe. Also turn off the logger when not required. Without the cellular radio, you battery will last for a long period. Bring a vehicle usb charger so that you can charge in between runs, or purchase a spare battery.
Which services will consume the most power?
In descending order:
- Onboard camera
- Device screen
- Cellular radio
- Wifi radio
- Bluetooth radio
What currency are your prices listed in?
All products are priced in US dollars. While we are headquartered in Canada, 99.9% of all autocrossers live and play in the United States. That’s also where we spend 99.9% of our racing budget! Given the fluctuating exchange rates, it does not make sense to maintain separate pricing for fellow Canadians. Sorry eh!
