The SX126x SDK contains several simple examples for SX126x transceivers.
| Name | Description | Documentation |
|---|---|---|
| CAD | Perform a Channel Activity Detection (CAD) - LoRa only | README |
| PER | Perform a Packet Error Rate (PER) test - both Tx and Rx roles | README |
| Ping pong | Launch an exchange between two devices | README |
| Spectral scan | Get inst-RSSI values in RX mode to form a heat map | README |
| Spectrum display | Get inst-RSSI values in RX mode to form a dyamic spectrum curve | README |
| Tx continuous wave | Configure the chip to transmit a single tone | README |
| Tx infinite preamble | Configure the chip to transmit an infinite preamble | README |
| Sigfox | Send a Sigfox-compliant uplink | README |
A demonstration of the LR-FHSS capability of the chip can be found here.
Each example has its own set of parameters - see sx126x/apps/<example>/main_<example>.h.
There is also a common configuration file sx126x/common/apps_configuration.h where parameters can be set, among which:
- Packet type
- RF frequency
- Output power
- Packet and modulation parameters for different modulations
See details in the common README
This SDK is developed on the ST Microeletronic NUCLEO-L476RG development board
