This is an attempt at creating an Arduino library for use on ESP32 boards with a CC1101 transceiver or SX127X Transceivers 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.
This is the LILYGO® LoRa32 V2.1_1.6.1 433Mhz board running OpenMQTTGateway.
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.
- One comment about the cc1101 transceiver module, I have found that the receiver is not as sensitive as a rtl_sdr and I get about 1/2 the range.

Datasheet for the CC1101 board I'm using
This is the Heltec SX127X board I used for development. I used the 433 Mhz Board
This is the LILYGO® LoRa32 V2.1_1.6.1 433 board I used for development. I used the 433 Mhz Board
Details are here
- OpenMQTTGateway - https://github.com/1technophile/OpenMQTTGateway
- Currently available in the production branch
- Firmware size tuning
- Further heap usage tuning
- Find stack leak when running all devices
- Enable additional pulse demod functions
- Simplify the process to update from the rtl_433 source
To determne that a signal is available for reception, the library watches the current RSSI reported by the transceiver module and when it crosses a predetermined RSSI threshold it enables the signal receiver function. End of signal is determined when the signal drops below the predetermined RSSI threshold for a minimum of 150,000 micro seconds.
The RSSI Threshold for signal detection is automatically determined based on the average RSSI signal level received aka RSSI floor level with a delta ( RSSI_THRESHOLD ) added to it. The average RSSI signal level is calculated over RSSI_SAMPLES.
For background see section 2.1.3.2. of SX127X Data sheet
To tune the SX127X OOK RSSI FIXED Threshold two values are used to determine if the threhold needs to be increased or decreased. The first is the noise recevied between signals. If the number of noise bits received between signals is greater than 100, then the threshold is incremented. Second is the unparsed signals. If an unparsed signal is received, but it has less than 20 pulses, the threhold is decremented.
The first approach is what is recommended in the SX127X datasheet, and the second is a control to lower the threshold if it is too high and incomplete signals are received.
