This is an attempt at creating an Arduino library for use on ESP32 boards with a CC1101 transceiver with the device decoders from the rtl_433 package. And be available for use with openMQTTGateway as an available module.
Inspiration for this came from the ESPiLight effort. Kudos to puuu for this, and the awesome package.
The initial port implements only enables a subset of the available modulations and device decoders, and is limited to devices I have access to and can test with.
OOK_PPM : Pulse Position Modulation
OOK_PWM : Pulse Width Modulation

The gaps in the numbers are device decoders disabled by default.
To wire my device, I followed this guide
https://github.com/LSatan/SmartRC-CC1101-Driver-Lib/blob/master/img/Esp32_CC1101.png
And to build the example I use platformio and opened the example folder as a new window and built from their.
- OpenMQTTGateway - https://github.com/1technophile/OpenMQTTGateway
- Currently available in the development branch
- Firmware size tuning
- Further heap usage tuning
- Find stack leak when running all devices
- Enable addition pulse demod functions
MINRSSI ; Default rssi to enable receiver, defaults to -82
MY_DEVICES ; Only include my personal subset of devices
DEMOD_DEBUG ; enable verbose debugging of signal processing
DEVICE_DEBUG ; Validate fields are mapped to response object ( rtl_433 )
MEMORY_DEBUG ; display heap usage information
RAW_SIGNAL_DEBUG ; display raw received messages
RSSI ; Enable collection of per pulse RSSI Values during signal reception
RTL_DEBUG ; Enable RTL_433 Verbose option ( 0=normal, 1=verbose, 2=verbose decoders, 3=debug decoders, 4=trace decoding. )
SUPPRESS_UNPARSED ; Enable suppression of publishing MQTT messages for unparsed signals, e.g. {model":"unknown","protocol":"signal parsing failed"…
-
Copy subset of files in src/rtl_433/devices without any modification
- Generated a list of files that used OOK_PPM and OOK_PWM with tools/device.awk
- Copied into src/rtl_433/devices
- Marked newkaku.c, nexa.c, and proove.c as unavailable as the device decoder triggers a stack overflow
- Based on the reduced list, updated include/rtl_433_devices.h, src/rtl_433_ESP.cpp, and src/rtl_433_ESP.h
