Cayenne cannot connect to Arduino connected to raspberry via USB


#1

Arduino is connected to raspberry pi 3 via USB. I am able to upload sketch to ardiono from Raspi.

However caynne cannot connect to arduino.

The cayenne app keeps “connecting to device” in an endless loop. Does anyone have similar problems


#2

do you have a ethernet shield or a esp8266 to connect to arduino for internet connect. as when using serial connection it is difficult to rule out cause of error without debug.


#3

I can use cable to my router for testing. Thanks for the tip.


#4

do you have Ethernet shield and have a look at this https://github.com/myDevicesIoT/Cayenne-MQTT-Arduino/blob/master/examples/Connections/EthernetShieldW5100/EthernetShieldW5100.ino

Hi

Thanks for the reply.

I do not have wifi shield. I think I will invest on that, the I do not need the USB connection at all.

better go for for Nodemcu or wemos board.
