RadioLib SX126x ESP32 Deep Sleep Example
|
||||
|
||||
This example listens and receives LoRa transmissions while
|
||||
deep sleeping the ESP32 MCU. Once a packet is received, an
|
||||
interrupt is triggered that awakens the ESP32. To successfully
|
||||
receive data, the following settings have to be the same on
|
||||
both transmitter and receiver:
|
||||
- carrier frequency
|
||||
- bandwidth
|
||||
- spreading factor
|
||||
- coding rate
|
||||
- sync word
|
||||
|
||||
Other modules from SX126x family can also be used.
|
||||
|
||||
For default module settings, see the wiki page
|
||||
https://github.com/jgromes/RadioLib/wiki/Default-configuration#sx126x---lora-modem
|
||||
|
||||
For full API reference, see the GitHub Pages
