Hi all,
I am looking at using a potentioneter to measure the position of a vane, have the resistance turned into a PWM Value, then sent wirelessly over a distance of about 5 meters. It will then be received by another device and the PWM signal sent to a servo, like a basic rc remote sort of (but it serves a different purpose)
I have 2 methods that i can try:
1: I have a servo tester that i have replaced the potentiometer on. Then the PWM output is wired direct into the Rx port on a ESP32 wifi board and then another ESP32 is located a distance away. The Tx port of the ESP32 is wired straight to the PWM input for the servo
I have already tried this method with a XD-RF module (pretty much the 433mhz one-way radio) but it produced a load of jitter, possibly from interference, as it is an analogue radio.
My question for this is, can 2 ESP32 modules talk to each other directly with no arduino attached? or does there have to be an arduino on the end to set everything up
2: the other option was to use a board like This and have it as a servo tester that sends it over the air to another module that somehow outputs the pwm signal out of a pin, and then that goes to the servo
The issue with No2 is that i have no clue how to code, and I am looking to make a simple model that requires no coding. I could possibly make it transmit the signal by modifying a simple servo tester but I'd have no idea how to set up a receiver module to output the PWM. If anyone has any advice on how to do that I would be greatly appreciative
TL,dr: can 2 ESP32 modules talk to each other out of the box without any form of coding, just data sent over Tx and RX? and is there a code already made for wirelessly transmitting and receiving a PWM signal
Cheers,
Henry
