v2.15.0

Significant Changes

Edge Services

With this release, uplink can also works as a platform for multiple apps running on the same device to communicate with each other, performing computation that would otherwise have to be performed in the cloud. This is supported by the following two feature additions:

1. On device bus supporting micro-services on the edge architecture.
2. Joins on data streams now allows configuring de-sampling and joining of data from different streams as received on bus before being pushed to the cloud.

Both of these features can be enabled and configured by adding the following to the config.toml:

[bus]
port = 1883
console_port = 3030
joins = { output_streams = [
    { name = "location", construct_from = [
        { input_stream = "gps", select_fields = [
            "latitude",
            "longitude",
        ] },
        { input_stream = "altimeter", select_fields = [
            "altitude",
        ] },
    ], push_interval_s = 60, no_data_action = "null", publish_on_service_bus = true },
    { name = "device_shadow", construct_from = [
        { input_stream = "device_shadow", select_fields = "all" },
    ], push_interval_s = "on_new_data", no_data_action = "previous_value", publish_on_service_bus = true },
    { name = "example", construct_from = [
        { input_stream = "stream_one", select_fields = [
            "field_x",
            "field_y",
        ] },
        { input_stream = "stream_two", select_fields = [
            { "field_z" = "field_x" },
        ] },
    ], push_interval_s = 120, no_data_action = "previous_value", publish_on_service_bus = false },
] }

• Support for remotely updating uplink config with an update_uplink_config action.
