espnow-rclink's Introduction

EspNow RcLink

RC Link library that works on ESP-NOW for tiny models in short range.

Features

ESP32 and ESP8266 support
Auto pairing
Up to 100Hz packet rate (or maybe more)
8 RC channels
Channels 1-4 are sent with full resolution and extended range 880-2120
Channels 5-8 are sent with reduced resolution and scaled for extended range 880-2120 (packed to 8-bit size, resolution is 5 units)
packet checksum checking

How it works

when reciever is powered it sends pair request
when transmitter is powered, it scans channels for pair request
when transmitter receive pair request, adds peer to the list and sends pair response
when receiver recieive pair response, adds peer to the list and start communicating only with this transmitter
transmitter will not accept any other pair request, until power cycle
receiver will not accept any data packet form other transmitter, until power cycle

Examples

Todo

Tests, a lot of testing required
Telemetry
RSSI
More channels

Request for S.BUS

Hey Man!
A big fan of your projects. I rly wanna try this one out as well. I just wanted to know if it is possible to use S.BUS instead of PPM which I think is being used right now. It would increase the option for more channels I think.

Also I have a doubt, As mentioned in the ESP FC guide we have to use the EspNow RCLink Tx, is it instead possible to use this code? because I am looking to DIY the whole transmitter with joysticks.

Do let me know!

Regards,
Arshaan.
