Android App Bluetooth Measuring Direction and Distance

Bluetooth Measuring Direction and Distance

Scenario;

Two BT BLE Devices;

Slave/Master or Master/Master

1. Device B decreasing distance < 5m to Device A;

a.) Device A send command X to Device B

Or

b.) Device B send Command X to Device A

------------------------

2. Device B increasing distance > 5m to Device A;

a.) Device A send command X to Device B

Or

b.) Device B send Command X to Device A

---------------------

Our present status;

1. We use Android app mechanism to calculate distance of BLE Device, bleu device using CC2540/BLE113 chips

2. We are using RSSI = TxPower - 10 n lg (d) formal to calculate distance, however we don’t have tx power value

3. We have calibrated tx power by keeping device at 1m, however results are not accurate

We need solution
