I'm testing a new idea of multi-cache as well as your knowledge of your handheld device. This is a "beacon cache" (one of the attributes).
First, walk to stage 1 and find the colorful art structures that resemble radio antennas in the park. One of the "antennas" is repeatedly sending you a secret code.
This is how you find the final coordinates:
Turn on Bluetooth on your smart phone or any devices supporting Bluetooth and start scanning.
When you see a device local name:
GC95ZPT-AAA-BBB, you'll get the final location at N25 02.AAA E121 31.BBB
If you use Android or Windows devices, you do not require any app download.
APPLE IOS, however, blocks viewing BLE devices from Settings->Bluetooth Menu. We suggest you to download "find my lost bluetooth device" by Best App Limited or "Bluetooth Smart Scanner" by Ace onto your iphone to read the codes. Other BLE scanner apps may work too. However, if your app reads "BRDA" instead of the device local name mentioned above, you may need to try another app.
BLE standards for Bluetooth Low Energy.
Contact CO if you experience any technical difficulties. Enjoy!
The cache is located outside of a building which sells all the greatest and latest gadgets in the market. Have fun!
