Conecting Arduino pro micro with NodeMCU

Hello

I have a problem conecting my pro micro with the NodeMCU. i'm using the pro micro to read 3 sensors (MLX909614) with I2Cmaster library and 3 sensors using the analogRead. On this part I don't have problems. I send the data using serial comunication with tx and rx pins; the data is recibed by the NodeMCU also conected to the tx and rx. but I can't see the values of the sensors on the serial print of the NodeMCO. Also the data will be published on a topic using the client.publish.

If somebody has done something like this and can help me I will be very greateful.

Thanks

what serial are your using on the two devices? e.g. hardware or software serial
what baud rate?
have you crossed the serial lines so that Pro Tx goes to NodeMUCU Rx and Pro Rx goes to NodeMUCU Tx?
