Detailed Setup
- creates myEnv.h in wio_terminal lib folder
cd wio_terminal/lib && echo "#define SSID \"\"\n#define SERVER_URL \"\"\n#define WIFI_PASSWORD \"\"\n#define BROKER_IP \"\"" > myEnv.h
-
Fill in the missing information in myEnv such as SSID, WIFI_PASSWORD, SERVER_URL, and BROKER_ID (this shouldn't contain port or protocol)
-
Start server using:
cd node_server
npm install
node app
-
Head to ServerConnectionHelper URL variable (android/app/src/main/java/com/example/home4u/connectivity/ServerConnectionHelper.java) and set it to the backend server URL
-
Head to BrokerConnection BROKERHOST variable (android/app/src/main/java/com/example/home4u/connectivity/BrokerConnection.java) and set it to the broker IP address without protocol or port
For the android application:
cd android && ./gradlew build
For Wio Terminal:
docker build -t wio_terminal_image ./wio_terminal
This will build the app inside a Docker image. To extract the built file, also run:
docker run --name wio_terminal_container wio_terminal_image
docker cp wio_terminal_container:wio_terminal/build/wio_terminal.ino.bin .
docker stop wio_terminal_container
docker rm wio_terminal_container
