Vext - PIN 21? RTC -IO ? Deep sleep wireless stick lite

#1

Hello Guys,

For the moment I have used the Vext with no problems as my sensor need to be power off when my esp32 goes to sleep. However now I need to keep my adxl 345 on when my wireless stick lite goes to deep sleep because my adxl345 will wake up my mcu.

So the problem is that you guys have selected a non RTC IO for the vext job, so I dont know how to keep it On when my mcu goes to sleep.

Any tips?

hi,

esp32 has an I/O hold function. You can find this API at the location in the picture.

I thought that the gpio_deep_sleep_hold_en() worked just for RTC_IOs however seems to be work for Vext PIN. Thanks!
