Notes

How to set measuredPower value?

You can’t pass measuredPower value as mbeacon’s command line argument. Because mbeacon failes to parse negative value. Use defaults command.

$ defaults write mbeacon measuredPower -integer -55

iBeacon’s measuredPower value is RSSI value 1 meter away from beacon.

If you want to measure real RSSI value (easily, I think)

• Set mbeacon’s measuredPower value around -55
• Find beacon from iOS device with any iBeacon app that displays RSSI value
• Move iOS device 1 meter away from beacon

Update mbeacon’s measuredPower value using real RSSI value 1 meter away from beacon.

# e.g. RSSI value 1 meter away from beacon is -45
$ defaults write mbeacon measuredPower -integer -45
$ mbeacon -uuid "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" -major 0 -minor 0
