How to use Memory Mode

Use Memory Mode to record sensor data with a PocketLab sensor when it is not connected via Bluetooth to a phone, computer, or tablet.

The default way to use a PocketLab sensor is to keep in connected to a computer, phone, or tablet via Bluetooth and record data to the PocketLab Notebook app. Use PocketLab's Memory Mode to record up to to 30,000 points of data directly to the PocketLab itself, without a Bluetooth connection. 

You must first set up Memory Mode with a Bluetooth connection to PocketLab Notebook or the IOS app. 

You can start a Memory Mode recording from one device and upload that data to another device. For example, you can start Memory Mode on the PocketLab iOS app (iPhone/iPad) and upload it to the PocketLab Notebook app (Chromebook, Mac, Win10 device, Android).

  6. Follow the directions to set up the sensors you want to record and the data rate. When you click Start the device begins recording.

    NOTE: Once the PocketLab memory fills with 30,000 points of data it will stop recording. Make sure you think about how long you plan to record when setting your data rate. If you want to record for a longer period of time, it might be best to use a lower data rate. 

  7. Your PocketLab sensor is now recording in Memory Mode. You can disconnect it from the app by clicking Leave App and Download Data later and it will continue recording data to its memory.

  8. When you no longer need to record data, you can turn the PocketLab off. It will keep the data stored, until you reconnect it to the app and download the data.

    NOTE: If the battery on the PocketLab completely drains the data in memory will be lost. PocketLab uses volatile memory, which requires some level of power to maintain. (Turning the PocketLab off won't lose the data. It will only be lost if the battery completely drains). 
  9. To download the data you have stored to memory, enter Memory Mode again using the same steps above. You will see the option to download the data from memory.
