I am trying to read a potentiometer data over firmata with node-red. potentiometer connects to analog pin of arduino and arduino is connect to raspberry pi over usb.
Program runs good and i can get the data from arduino but connection lost very often. Connection establish after 1 second but it cuts off so often.
What can i do to correct this?
The transfer rate is so high and i don't need a speed like this. Can i decrease the connection speed? Do i adjust the firmata for connection speed?
Hi there I've not tried your setup but I would say yes, drop the speed, you're not sending a lot of data so slow it right down see if it's more stable.
thanks alot, i have learned how to change baud rate at firmata
editing this will give me a lower baud rate,
but how can i change it in node-red site?
well what are you using in node-red to read the data? i.e. what node (full name please node-red-contrib-xxxx?)
have you looked at that node's options?
the Firmata node expects the default firmata install on the Arduino so no you can't easily change the Node-RED end.
