Android send data to Bluetooth LE device, using HM-10 BLE Module

My previous post show how to “Modified BluetoothLeGatt sample for HM-10 (Bluetooth LE Module)”, to receive data. It’s modified to echo the received data back HM-10, to sender.


London’s Gatwick Airport presently has 2,000 beacons for in-house navigation

Complex in-house environments like air-ports and department stores is often a problem to find your way around. And although Google is hunting cell phones with 3D detectors as one prospective solution for places GPS won’t accurately reach, another approach is to kit out an interior with many Bluetooth beacons – giving smart phone users located-locked pings to fix onto to recognise where they’re.

The UK’s second busiest air-port, Gatwick airport, has opted for the second solution to power an indoor navigation system it’s launching as a section of a bigger, multi-year transformation program.

It’s currently completed providing its two terminals with around 2 Thousand battery-powered beacons to ensure that digital map users will get a more precise blue dot as they walk around. The beacon system will likewise be utilized to power an augmented reality wayfinding tool – with the intention that mobile users can be guided to a particular locations inside the terminals through on-screen arrows. The beacon system is slated as supporting positioning with +/-3m accuracy.

Gatwick is intending to integrate indoor positioning into some of its applications, and says it’s in discussions with airlines to utilize it for their own applications and services – giving instance of them having the ability to send push notifications to inform people if they’re running late, or even settle on if they should wait or offload luggage so an aircraft can take off on time.

Shops and other third parties will likewise be able to use the system for proximity detection of potential consumers and delivery marketing messages – as a minimum to those who have signed up to receive them.

Gatwick says it will not be gathering up any personal information using the beacons but says “generic information on ‘people densities’ in different beacon zones” will be used to assist in improving airport operations – similar to queue measurement, streamlining passenger flows and decreasing blockage.

The airport has worked with UK start-up Pointr on the system. In addition to developing software and managing the system on an ongoing basis, Pointr offers an SDK with support for 3D AR wayfinding to enable third parties to tap into the functionality.
