Hello, I never tried it (I will soon), but there is a webpage about it on Node-Red org website. Interacting with ArduinoI understand the Arduino sketch and Node-RED are both running in the IOT2040, but maybe this is a way to go. Best regards, Hugo |

I have tested this now. You can use MQTT for having a data exchange between Arduino and node-red. Therefore you have to use the mosquitto broker on the IOT2000. On Arduino side you can use PubSubClient (comes with examples) and on node-red the pre-installed MQTT nodes. It did it with an IOT2040, because the PubSubClient uses the Ethernet.h library which claims the eth0 interface. So you won't have access through this interface to the IOT2000 anymore. Best regards! |

so there is no internal connection here? will I have to run both ehternet ports in order to move data from the "Arduino side" to the "Node Red Side"? |

No, the IOT2040 acts as a broker so the Arduino sketch will send data to the broker and node red will get the data from the broker. |

Hi, there is the possibility to write/read to/from a file with an Arduino sketch. You also can write/read to/from files with node-red. So this should be the easiest way to exchange data There are some examples attached! Best regards! Attachmentsketch_sd.zip (627 Downloads) |
