I'm working on Bluetooth Low Energy (BLE, Bluetooth Smart or Bluetooth 4.0) technology since summer 2013 and after few hundred hours code work my first BLE product(iCELL) ready to show and I'm happy to share here with the community.
May be you know, Some Android devices and all iPhones(since 4S) including this low power transceivers.
I think BLE will be most important interaction method for near devices at the future. Currently you can find thousands different BLE device on the market and hundred thousands coming.
iCELL hardware is a small electronic hardware with 8 cell battery reading capability and you can easily connect it to balance port of your LiPO to read battery voltage and cell conditions from your iPhone or iPad. (details here)
BLE has some limitations. The range around 30-100 meters. Data speed ~200 byte per seconds max. Not useful for drone data telemetry but possible to make your multirotor settings before flight or checking some important variables when your platform passes above you.
Main advantage is iPhone/iPad/Android. Everyone has one of them. Software update is easy. Screen is tough sensitive. Resolving all display problems on a single platform.
The second big advantage is "Low Energy". BLE devices can works 1 year with a coin cell.
Now I'm working on a weather station for house usage, a camera trigger for timelapse, a camera slider and lost plane beacon. All of them working over BLE.
Please share your opinion about iCELL idea. is it useful? or useless?
and If you have any new idea for BLE technology please feel free. I will glad to work over it.
