Logging Data on STEVAL-STWINKT1B Without BLE

[anthonyADV]

Hey,

I'm using the STEVAL-STWINKT1B sensor to log data, and I was wondering if there's a way to do it without connecting via BLE (through the ST BLE Sensor app on iOS). I know it's possible to log data using NanoEdgeAI — which I’ve successfully done — but I was hoping there might be a simpler method.

Specifically, is there a way to just power the sensor with a battery, insert the SD card, and start logging data by pressing a combination of buttons (like holding down the reset button for a few seconds, etc.) — without needing any app or external interface?

Best,

Anthony

Hello @anthonyADV 

 

The two methods you describe (NanoEdge and the BLE sensor app) are the simplest options and what I would recommend to anyone starting.

For anything else, you need to develop the firmware by yourself.

 

Have a good day,

Hello @anthonyADV 

In addition to what already said by @Julian E. , let me add a comment regarding DATALOG2 example.

You can use with or without BLESensor app: I strongly suggest to use it to setup sensors and acquisitions, but it is not mandatory. Logging can start also by pressing USR button with SD card already inserted. You can find all the details in the Quick Start Guide.

 

Best regards
