Flash Logging
To log ECG, PPG, or temperature data to on-board flash memory, perform the following steps:
1. Set up ECG, PPG, or temperature measurement on the PC GUI or Android app as
instructed in the Using the PC GUI section or in the Using the Android App section, and
ensure that the box for “Log to Flash” is checked and the box for “Log to File” is unchecked.
2.
Click “Start Monitoring.” The device displays “REC” to indicate that data is being logged
to flash. Data is not streamed to the GUI or app while Flash Logging is enabled.
3. At this point, you can disconnect the USB Type-C or cable or BLE connection to log data
while untethered.
4. To stop flash logging while untethered, press the down button on the right side of the
watch. The display
should return to “USB.” If the watch is still tethered to the PC or Android
device
, flash logging can be stopped by pressing the “Stop” button in the GUI or app.
Downloading the Log File
After flash logging is complete, download and parse the log file by performing the following steps:
1. Ensure the USB Type-C cable is not connected, and power off the watch by holding the
power button on the left side of the watch for 3 seconds.
2. While holding the up button on the right side of the watch, insert the USB Type-C cable
(or the Pico adapter board with a USB Micro-B cable) into the USB Type-C connector of
the watch. Continue holding the up button until the indicator LED on the right side of the
watch turns blue.
3. If done correctly, the watch boots into mass storage device mode and displays
“MSD.”

from the device.
