I recently got a Wireless Stick Lite board for prototyping a Lora end device. Previously was using a WiFi Lora 32 (v2).
The board does in general consume less power. But when tested the deep sleep mode in the provided in the examples (same code @hunter8801 used here WiFi LoRa 32(V2) deep sleep low power test) I get about 2.67 mA when the board is powered from a 3.7v 750mAh RCR123a battery. The description claims 35 microAmps in deep sleep mode.
Only changes I made to the example was disable the display in the Heltec.begin() method, since this board doesn’t have a display and I increased the sleep/active period to 30 seconds, so I have some time to read the values from my multimeter.
In active time, the board is drawing around 44mA.
Setting RTC peripherals to sleep also didn’t make much difference. Is there anything specific that needs to be configured besides running that test?
