1. SensorHub Events

onEvent("sensors.sample", function () {
  //
});
onEvent("sensors.flush", function () {
  //
});

sensors.sample

Fired when the SensorHub module is requesting all register modules to provide a sample. Each module should call sampleAdd to send one or more measurements as a response to this event.

sensors.flush

Fired when the SensorHub has finished flushing the data to the uplink modules.

2. Uplink Events

onEvent("uplink.error", function () {
  //
});
onEvent("uplink.done", function () {
  //
});
onEvent("uplink.data", function (data) {
  //
});

uplink.error

Fired when the Uplink module has encountered an error while uploading the data.

uplink.done

Fired when the Uplink module completed the transmission.

uplink.data

Fired when the server has responded with some downlink data. The data argument is a binary string with the incoming data.

3. UART Events

onEvent("uart0.data", function (data) {
  //
});
onEvent("uart1.data", function (data) {
  //
});

uart0.data

uart1.data

Fired when there is an incoming data chunk on either of the UART0 or UART1 interfaces.

Note that UART1 is available only when a respective peripheral is installed on the device.

4. System Events

onEvent("runlevel.changing", function (toLevel, fromLevel) {
  //
});
onEvent("runlevel.reached", function (toLevel) {
  //
});

runlevel.changing

runlevel.reached

The runlevel.* events are dispatched when the kernel is switching run-levels. Refer to getRunlevel() function above for more details on run-levels.

The runlevel.changing is dispatched when the system is about to switch run-levels. This can occur for example when the external power supply is disconnected or re-supplied.
