"net.rssi" diagnostic data

[sergeuz]

Problem

The system should expose RSSI diagnostic info on platforms that have a wireless network module.

Solution

Add net.rssi diagnostic data source.

Example App

#include "application.h"

namespace {

const Serial1LogHandler logHandler(115200, LOG_LEVEL_WARN, {
    { "app", LOG_LEVEL_ALL }
});

bool logDiagData(void* appender, const uint8_t* data, size_t size) {
    Log.write(LOG_LEVEL_INFO, (const char*)data, size);
    return true;
}

} // namespace

void setup() {
    uint16_t id = DIAG_ID_NETWORK_RSSI;
    system_format_diag_data(&id, 1, 0, logDiagData, nullptr, nullptr);
    Log.print("\r\n");
}

void loop() {
}

lgtm. When is the DiagnosticSource added to the diagnostic service?

The registration happens in the constructor of AbstractDiagnosticData: https://github.com/spark/firmware/blob/feature/diagnostics/wiring/inc/spark_wiring_diagnostics.h#L170
