This Flutter function, calculateDistance, is designed to estimate the distance between a Bluetooth device and its transmitter based on the received signal strength indicator (RSSI) and the transmission power (txPower).
Parameters #
txPower: Transmission power in decibels (dB) at 1 meter from the Bluetooth device.
rssi: Received Signal Strength Indicator, representing the signal strength received by the device.
Return Value #
The function returns the estimated distance between the Bluetooth device and its transmitter. If the distance cannot be determined, the function returns -1.0.
Usage #
void main() {
// Example usage
int txPower = -10; // Replace with the actual transmission power value
double rssi = -55.5; // Replace with the actual received signal strength

double distance = calculateDistance(txPower, rssi);

if (distance == -1.0) {
print("Unable to determine distance.");
} else {
print("Estimated distance: $distance meters.");
}
