Have modified code from “Ebyte LoRa E32 device for Arduino, esp32 or esp8266: WOR (wake on radio) and new ESP32 shield – 8” for the E220 library. Experiencing some compiler errors; requesting help resolving errors.
Hi William,
The E220 has a different setting structure; please take a look at the examples of the library. Here, you can find the WOR sender and WOR receiver configuration.
Converting nRF24L01 receiver and sender sketxhes to use E220-900T30D transceivers using E220 library. Sender part is working; having issue with structure. Plan is to expand structure in future; for now only 1 variable, switchState. The value should be 1 or 2; value for 1 on the receiving structure when read is 18285312. Have searched the web;very few returns.
I am using E220 library examples “pieced” together WOR, Sending of structure. Must say I am easy to confuse; likely missed something critcal to success.
Hi William,
It’s normal the device use a WOR cycle to check if some message is coming, you can find more information here.
WOR Cycle
A critical configuration parameter is WOR Cycle, for the sender is essential because It adds a long preamble to the message (long as wake time). The handset uses the wake-up time as the cadence for checking a wake-up message. So if the receiver checks every 2000ms (polling time) if there is a message, the sender adds a 2000ms preamble. The receiver intercepts the message preamble, waits for the actual message to read, and returns to power save mode.
So If you want to maximize the power save, you must put minimal WOR Cycle. If you want more efficiency, you must do the inverse.
