I have an array of data from MQTT to Nodemcu. I deserialize that data to turn on/off the led indicator in Blynk. But the process is too slow. How can I make it fast?
void callback(char* topic, byte* payload, unsigned int length) {
Serial.println("Message arrived");
Serial.println(mqtt_topic);
Serial.print("Message arrived in topic: ");
Serial.println(topic);
Serial.print("Message: ");
for (int i = 0; i < length; i++) {
Serial.print((char)payload[i]);
}
Serial.println();
String payloadString = "";
for (int i = 0; i < length; i++) {
payloadString += (char)payload[i];
}
Serial.println(payloadString);
DynamicJsonDocument doc(1024);
doc.clear();
DeserializationError error = deserializeJson(doc, payloadString);
if (error) {
Serial.print(F("deserializeJson() failed: "));
Serial.println(error.f_str());
return;
}

I have tried to add the millis to the program but ot won't work, and i tried to add jsonbuffer but it's not working too. And i hope that the deserialize process will be faster
