The product is act as a beacon and its location track by other fixed BLE readers to positioning it in particular defined area. Wearable device is track by based on RSSI recieved by fixed reader, buten-USTelligent Community 13Tue, 21 Feb 2017 12:27:40 GMThttps://devzone.nordicsemi.com/thread/77137?ContentTypeID=1Tue, 21 Feb 2017 12:27:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e472b793-ae4e-48bd-ae45-8d17143108e1SaurabhPatel<p>Thanks @awneil for the response with useful links.
