I am currently doing a project related to communicating with power analyzer. When i directly connect the power analyzer with my laptop and send a command using Putty or hardware terminal it responds back. But when i program an arduino uno and node mcu to do the same, the power analyzer doesn't respond.
I am connecting the power analyzer to node mcu using OTG cable and then using rx tx to make the node mcu communicate with the arduino uno which is then connected to my pc. I am sending commands from the serial terminal of arduino ide.
transmitter code->arduino uno
Reciever code->node mcu

Maybe the power analyser serial port needs other pins connected?   Can you post the wiring diagram?

HOW are you connecting them? Serial? USB? Duct tape?
The art of getting good answers lies in asking good questions.
