It works like a “black box”: data is saved in \u003cstrong\u003eTXT\u003c\/strong\u003e format on the SD card, and parameters can be configured via a generated \u003cstrong\u003econfig.txt\u003c\/strong\u003e file. Two styles are available: \u003cstrong\u003eJY-DATA-LOG\u003c\/strong\u003e (standard) and \u003cstrong\u003eJY-DATA-LOG-BLE\u003c\/strong\u003e (Bluetooth\/BLE
