ESP32-S3, SX1262 LoRa with Duty Cycle, Wake on Radio, and Deep Sleep

GitHub project "EoRa PI Foundation" receiver has 175 µA average current consumption using SX1262 LoRa Duty Cycle and Deep Sleep. Current measurement images; done with Nordic Power Profiler Kit II. 

Project is a web based, remote load controller. Async web server, receives web request. LoRa transmitter sends two packets in one transmission. First packet is the Wake on Radio preamble, the second packet is the payload; turns on load, calls radio.sleep, sets external wake up timer. Timer expires, turns off load, devices enter sleep; await for cycle to repeat. Original use case was for a Wyze Cam3, power bank switch to conserver battery power. Web request came from website link; the two packets, one transmission keeps the web experience to a single click on the link.

Ideal Applications

  • Remote equipment control in field deployments (months of operation)
  • Battery-powered IoT sensor networks
  • Agricultural automation systems
  • Emergency/backup communication systems
  • Environmental monitoring with long-term deployment
  • Camera activation systems (original use case)

    Yes, well documented with examples; board config file and utilities file that help with programing.  No deep sleep examples; however, they do provide a RadioLib Interrupt example that was a help in the project.  I leaned heavily on Claude.  SX1262 was new to me had worked with e220 in another similar project.  One thing about this board; only 26 GPIO pins are exposed, not all are io useable.  Claude created a table with physical pin number, GPIO number, RTC number, Wake capable noted, and usage note; very useful.  Included in my project Docs folder.  Real "treasure" of documentation for anyone working with "EoRa-S3-900TB from EbyteIoT.com.  Great development board under $20... many features!  Another great feature built-in LiPo battery charger!

    Interesting module.. even has a built-in display! 

    I've tried one or two smaller/simpler eByte modules in the past; they make nice stuff.
