This is an example controller application for synchronizing clocks of end devices using LoRaWAN.

The controller application requires the following environment variables set:

First, install the dependencies:

$ yarn

Then, build the application:

$ npm run build

Run the application:

$ npm run start

You should see an output similar to this:

> lorawan-stack-example-clock@1.0.0 start /dev/src/lorawan-stack-example-clock/controller
> node dist/index.js

sync clock dev1: now = 2019-05-10T12:07:19.234Z; target = 2019-05-10T12:07:29.000Z; unix time = 1557490049

The controller schedules a downlink message 10 seconds from the current time.
