ESP32 Forum

I'm troubleshooting some power problems, and have a few questions.

Table 6 of the June 28 ESP_WROOM-32 Datasheet indicates the module consumes 0.8mA in light sleep mode. What system (hw/fw) configuration did the Espressif team use to obtain the 0.8mA measurement ?

What are other people seeing for the wroom32 light sleep current ?

The board I'm using consumes about 35mA during light sleep, and 500uA during deep sleep.

I'm running the v2.1/rc1 code. I added a vxTaskDelay(1000*configTickRateHZ) into the deep sleep example code, and the current does decrease fom ~50mA to 35mA during this delay (which should trigger light sleep), but I expected a much lower current.

Thanks!

Deep sleep is not in esp-idf yet; what you're seeing is the effects of just the WAITI Xtensa instruction. We expect light sleep to go in in 3.0.

Thanks for the quick reply. What is the estimated release date for esp-idf 3.0 ?
