The file name doesn't correspond to the contents. Should probably be rc_parser or rc_reader
This is currently not an RC reader - it's an RC-read-and-sender-to-ESP - a relay one may say; however, it's best to have an RCReader class and an ESPTransmitter (or how you want to call it) to send data to the ESP. Now it is too convoluted
My concerns:
