Just do a range and speed test.
- With phone app only (without the beacon nor the controller)
- Firmware 15.10.17
- Wind level 2
- Open place
- Max. speed > 6m/s or 21.6 kph (13.4mph)
- Max. range ~ 120m (393.7ft)
- Within the range of about 120 meters, the phone connection is good, and there is no abnormality.
- Slightly more than 120 meters, the screen of the mobile phone was significantly delayed, and a lost signal message also appeared.
- Acceptable and quite good
- It will be better to operate with the controller. (I guess)
