The Sony Smartwatch 3 (SWR50) and LG Watch Urbane 2nd edition were of the very few smartwatches able to read the Libre sensor with their internal NFC reader, and gave birth to early projects as a bridge. This is now an archived project, some guidelines are still available here.

Most required resources are not available anymore on the web.

xDrip+ supports this feature with the data source LibreAlarm.

Patch the SWR50 watch to enable the NFC reader

Install LibreAlarm on your phone

Install the LibreAlarm watchface on the SWR50

Use these guidelines for LibreAlarm instead of xDrip+.

Setup xDrip+ with LibreAlarm data source.

xDrip+ will receive BG readings from the LibreAlarm app.
