sendTelemetryJson require a trick to work correctly

[HernanBadillaV]

Hello.

I have the next code working fine

void sendAllTelemetry() {
// Calcular el tamaño del JSON
size_t json_size = measureJson(submonitorTelemetry);

tb.sendTelemetryData("flush", 1);   // <-----
bool success = tb.sendTelemetryJson(submonitorTelemetry, json_size);
Serial.println(success ? "Envío exitoso" : "Error en el envío");
tb.sendTelemetryData("flush", 2);   // <-----

// Limpiar el documento JSON para la siguiente ronda
submonitorTelemetry.clear();
tb.loop();

}

However if I remove the lines
tb.sendTelemetryData("flush", 1); // <-----
tb.sendTelemetryData("flush", 2); // <-----

This instruction does not work correctly.
bool success = tb.sendTelemetryJson(submonitorTelemetry, json_size);
"success" result on true but the info does not reach the TB server.

I am development on windows 10 VSC 1.97.2 with platformio core (6.1.17) Home (3.4.4)

The code is running on esp32 wrover.

Best regards.

Can you write #define THINGSBOARD_ENABLE_DEBUG 1 at the top of your main.cpp file. And attach the log outputs you receive in the console.

Because only from the given information I can not debug why sending telemetry should not work. The only additonal important info is that the boolean returned by sendTelemtryJson only shows that sending the json was successfull, but it does not mean that the mqtt broker could actually send it to the cloud. This is the case because MQTT with QoS 0 is fire and forget.

Thanks for your assistance. I'm not sure how the problem was fixed. I've learned about a very useful parameter that I didn't know existed (THINGSBOARD_ENABLE_DEBUG 1).

Best regards.

Did you test your application again with the fork and the THINGSBOARD_ENABLE_DEBUG 1 enabled?

Yes. It works OK both times.
