We are building two combination app+bluetooth (4.0) devices to bridge various communication tools (315Mhz, 433Mhz etc.).
This device is a bluetooth keyfinder. It should have the following design features:
- Ability to attach to a keychain
- Method to put the device in pairing mode (either by shake/impact sensor, button or other method)
- Visible RGB LED
- Room for a buzzer/speaker
Please see ApKey.com for more details (although it's somewhat under construction)
Ideally, the two devices should follow a similar design style.
