Troubleshooting and FAQs
Below are a few troubleshooting tips and frequently asked questions that can come up when working with the OpenLog Artemis. Make sure to check the following scenarios for possible solutions and answers to your questions.
I’ve Connected a Fresh LiPo battery and My OLA is Not Logging.
Your OLA is probably in deep sleep and needs to be woken up. Give the RST button a press and you should see the STAT LED light up immediately and flash once logging has started.
I Connected My Own Battery and My OLA Does Not Work Anymore
Did you check the battery polarity? Some batteries have the opposite polarity as opposed to the batteries in the SparkFun catalog. Unfortunately, connecting one of those will destroy your OLA.
I’m Using a Large SD Card and My OLA is Not Logging.
As of firmware v1.11, the OLA supports exFAT SD cards in addition to FAT32 cards. Please ensure your card is formatted correctly; we recommend the SD Association Formatter.
My RTC Keeps Being Reset Back to Zero.
Please have a look at the “Low Power Considerations” section. The RTC will reset if: the RTC battery discharges; you attempt to reset (wake) the OLA without a power source connected.
My Stop Logging Button is Not Working.
Stop Logging needs to be enabled through the configuration menus. Please see the “Configure Power Options” section for more details.
My Log File is Showing Zero Size.
This can happen if the log file is not closed correctly or if the SD card is removed before the power is turned off. The data is probably still on the card, but the File Allocation Table has not been updated correctly. We recommend adding a stop logging button to completely prevent this.
There are active disk editor tools which you can use to search for and recover your data, but this is something for advanced users only.
I have Two of the Same Sensors Connected to the OLA - Neither are Working.
Each device on an I2C (Qwiic) bus must have a unique address. If your sensors cannot be configured with unique addresses, you will need to use a Qwiic Mux to isolate them. Please see “Qwiic Sensors and Muxes” above for further details.
If you need technical assistance and more information on a product that is not working as you expected, we recommend heading on over to the SparkFun Technical Assistance page for some initial troubleshooting.
If you don't find what you need there, the SparkFun Forums are a great place to find and ask for help. If this is your first visit, you'll need to create a Forum Account to search product forums and post questions.
For additional feature requests, we recommend filing an issue in the OpenLog Artemis GitHub repo for consideration. Please note that this does not guarantee that the feature request will be added depending on the complexity of the request.
