Explore

Android app to interact with your environment through BLE advertisements. A back-end server written in Go with Redis supports the app.

description

Communication between android-client and go-server is done using a TCP/IP sockets. The app currently provides ability to scan for BLE advertisements. A location name can be associated with that chip's MAC address. Once associated users can store messages at that location (assuming the advertisment is from a beacon that stays at that location). Other users retrieve those messages when scanning near that beacon.

config

1. Copy explore/go-server/test-config.toml to config.toml
2. Set Port and change Redis if redis is not running on same machine
3. Copy explore/android-client/app/src/main/assets/default-config.properties to config.properties
4. Set host and port

go-server requires toml and postgres libraries

go get github.com/BurntSushi/toml
go get github.com/lib/pq

running

Install go dependencies and start redis on port 6379, then start the server

cd go-server
go run main.go &

To run on LAN you need to figure out what your computers internal IP for your network is. Running ifconfig on my computer shows inet addr:192.168.1.101 under the wlan0 entry. That is the IP you will want to use as the host param in the android config. Keep the default port 8082.

Build android app then install app-debug.apk found in android-client/app/build/outputs/apk

cd android-client
./gradlew assembleDebug

After installing open up device and open up Settings. Confirm host and port match your server. You can then Start Scan and nearby beacons will be displayed.
