hi, we're trying to take data from arduino to ros, and send some value corresponding to it, back to the arduino. on the arduino side, the publisher works well but on the ros side the publisher is not publishing the data. we've tried the publisher and subscriber individually using python on ros side, but working with both of them is creating a problem.

When you say "on the arduino side, the publisher works well", could you be a bit more specific? (e.g. "values from the arduino are visible in the serial-monitor in the Arduino IDE", or "values from the arduino are published by a ROS node that reads values from the arduino via a serial conn", or ...)

Are you using rosserial_arduino? Please be very specific about what topics are being published by what things, and what are subscribing to those topics, and which exact ones are not working.
