How ever powering from usb is not very stable. When sending multiple messages with delays my sketch sometimes stalls. Need to test with the suggested 6v power supply though. But most nodes don't need to send multiple messages quickly
@evb said in Please give me an advice for a simple sensor node:
But the node will continue to work till 1.8V in a safe operating area.
Yeah sure, but alkaline batteries are nearly depleted when they get to 1V, so barely worth the hassle.
@mrussi I am also interested in using an esp32 with lora as the gateway. Did you make it work?
I planning to buy, https://www.botnroll.com/en/esp/2979-esp32-wifi-bluetooth-lora-sx1278-433mhz-with-0-96-oled-display.html
