Re: Additional current draw in Deep Sleep+ULP if WiFi.begin() called

This is a regression in recent versions of ESP-IDF. We are working on a fix. For now you can add a call 'adc_power_off();' (from driver/adc.h) right before entering deep sleep. Excellent! Thank you. Do we have to call adc_power_on(); when the ESP32 wakes up from light sleep? Or is ADC re-enabled wh...

Re: Additional current draw in Deep Sleep+ULP if WiFi.begin() called

Ive noticed this problem too... In my program, if I initialize WiFi and then want to put the ESP32 in light-sleep, it uses 1.5-2mA more than if I never initialized WiFi at all. Ive tried calling: esp_wifi_stop() WiFi.mode(WIFI_OFF); esp_wifi_set_mode(WIFI_MODE_NULL) None of them COMPLETELY shut off ...

Re: CAN-Bus API multiple filter configuration

Why cant you just do a simple software setup?

ie

if (rx_frame.MsgID == 0x123)
{
read the message in and do something with it.

Re: Is there any dev kit with 16MB flash?

Has anyone gotten the 16mb flash to work with the Arduino IDE? What is the procedure?

Re: ESP-WROOM-32 and extending the flash

ESP-WROOM-32 modules with 8 MB and 16 MB Flash are now available (as well as ESP32-Wrover modules ), so there is not much need for adding the external flash chip. Very cool! Ive been waiting for someone to make custom WROOM32 with 16MB of flash, that is also FCC certified with the metal RF shield. ...

Re: ESP32 Arduino SSID, PASSWORD not update

I have encountered this once before...using Arduino, the SSID and password seemed to be "permanently" burned in and would not change by uploading a new sketch. Try doing a complete force-erase manually using esptool.py. Then reflash your program using the Arduino IDE. That should clear any existing ...

Re: md5 Error while flashing ESP32-WROVER

Every once in a while I too get that random MD5 error when reflashing the ESP32. Cycling power always fixes the problem though...

Re: Processor utilization in percent

Curious if anyone else has any updates on getting CPU utilization working in % using Arduino?

I'd like to print each core's CPU utilization in "xx%" in a serial terminal window...

thanks
