i need cayenne to work countinously with the amped heart sensor,i used the instruction cayenne.run();
but i have the following problem error: ‘class CayenneMQTTWiFiClient’ has no member named ‘run’
Cayenne.run();
could you help me with that?

Cayenne.run()
is for old library. You need to use Cayenne.loop()
i used cayenne.loop(); and y code is compiled well but nothing appears on cayenne or either lcd,here is my code:

Follow this tutorial and first get your device connected to cayenne Adding a New Device using MQTT
hi haya.mansour
Have you successfully connected the heart rate sensor to Cayenne?
I hope you reply my email. thank you

do not create multiple post on same topic.
owh i’m sorry
