Cayenne decode some payploads

[menyDev]

Hi, I am confused with this, I run the code 1 on my Wireless Stick Lite from Heltec and when I decode with CayenneLPP on ttn everything works fine, but then I do just one modification (code 2) and set other value to send and try to decode the payload the output is invalid on ttn.

What’s wrong with my code? I’m a beginner with Cayenne and ttn but I would think that the codes are almost the same

Code 1: `#include

include

CayenneLPP lpp(51);

void setup() { Serial.begin(115200); }

void loop() { lpp.reset(); lpp.addTemperature(7, 26.5f); lpp.addRelativeHumidity(8, 86.6f);

uint8_t *payload = lpp.getBuffer();

char buffer[7]; String payloadString;

for (int i = 0; i < lpp.getSize(); i++) { sprintf(buffer, "%02x", payload[i]); payloadString += buffer; }

Serial.print("HEX: "); Serial.print(payloadString); Serial.print(" | SIZE: "); Serial.println(payloadString.length());

delay(5000); }`

Code 2: `#include

include

CayenneLPP lpp(51);

void setup() { Serial.begin(115200); }

void loop() { lpp.reset(); lpp.addVoltage(1,3.2f);

uint8_t *payload = lpp.getBuffer();

char buffer[7]; String payloadString;

for (int i = 0; i < lpp.getSize(); i++) { sprintf(buffer, "%02x", payload[i]); payloadString += buffer; }

Serial.print("HEX: "); Serial.print(payloadString); Serial.print(" | SIZE: "); Serial.println(payloadString.length());

delay(5000); }`

The output for code 1 is HEX: 076701090868ad and for code 2 HEX: 01740140

I also test with .addGenericSensor()and .addSwitch(), and the ttn output decoded is the same

Hi @jazhe Voltage is not supported on TTN. This library extends the original CayenneLPP with new data types. If you want to decode all of them on TTN you have to use the payload formatter you can find under the decoders folder (the minified version).
