    Using CY5677 to estimate BLE beacon distance

    colin.gerrish

      I'm pretty much a noob with Cypress BLE PROC/PSOC but loving the cypress BLE dev environment. I want to use my CY5677 USB dongle to scan for BLE iBeacons in order to determine an estimate distance for any beacons detected based on TX power and RSSI.

         

      I'm stuck on the basics. Typically a beacon / another PRoC assigned as a beacon will transmit a predefined data packet (lets say iBeacon format). This typically includes an RSSI value from the beacon. Do I treat this as TX power and then use the CY5677 to estimate it's RSSI value to then calculate beacon distance based on a standardised formula (there's a few available if you search online).

         

      Insight / pointers greatly appreciated.

         

      Thanks.
