How to register my homemade LoRa node

LoRa
1

Hi everyone,

I have made my own LoRa node with an Arduino Pro Mini + a RFM95 module + a sensor

I have registered it on The Things Network and everything works fine : I can see the data on TTN but I’d like to create my dashboard on Cayenne Mydevices.

The problem is… I don’t understand how to add it on Cayenne?

I have :
• Used the Arduino library “Cayenne LPP” with the following code :
// RECUP DATA FROM SENSOR
float distance= getDist();
Serial.println (distance);
//CREATING CAYENNE BUFFER
CayenneLPP lpp(20);
lpp.reset();
lpp.addDistance(1, distance);
//SEND DATA
LMIC_setTxData2(1, lpp.getBuffer(), lpp.getSize(), 0);

• Added the Cayenne integration on TTN

How can I add my device on Cayenne? LoRa>The Things Network> …?

Thanks !!

Marie

you need to select CayenneLPP

I’ve done it, entered my DevEUI, but no data is appearing on Cayenne :confused:
Thanks for your answer btw :slight_smile:

can you share the code you are using and which lora node it is.

where is this in above code?

I copied the wrong code… The edit is done above
Sorry

there is a code example here Convert to Cayenne LPP - #3 by marco_rudolph
