Create a struct for sending TelemetryEvent, and a future representing the telemetry loop.
Every 15 seconds, the telemetry loop will query for MLME/PHY stats and update various
time-interval stats. The telemetry loop also handles incoming TelemetryEvent to update
the appropriate stats.
Create a struct for sending TelemetryEvent and a future representing the telemetry loop . Every 15 seconds the telemetry loop will query for MLME / PHY stats and update various time - interval stats . The telemetry loop also handles incoming TelemetryEvent to update the appropriate stats .
