Proximity Finder (Lost Finder)~BLE (Bluetooth 4.0) Application
I have evaluated several lost finder products.
To my suprised, the new company called as StickNfind is the one which is the most usful one.
The design normally is set as working in certain distance far.
Excepting StickNFind, other suppliers proximity finder mostly has misworking happened.
For example, when set alarm at 5M, but start woring in 1M or 2M in actual case.
This problem may due to the interference of mobile, WiFi or other wireless device.
Market Products Testing
Therefore, promixity finder actually not only a works for APP (unfortunately most suppliers think so), but BLE design is also a task to enhance the accurancy! Only with the accurancy, this products may able to spread to consumer market widely!
