Re: Higher current consumption (100uA) in Deep Sleep on ESP32-WROOM-32D

Thank you very much for your replies! I believe that So_yeah highlighted the problem here. Moreover, I was doing a mistake while measuring the current consumption in the first place. It is not 100uA, but it is in the order of 2mA. I am supplying directly 3.3V, but I noticed from the schematic of the...

Re: Real-time data streaming over WiFi

Thank you for the replies :) I did not know about the ESP-NOW protocol. It is very interesting indeed. However, I would need something simple to be integrated with a python script running on a PC that is receiving the data. That is why I was thinking about UDP. I also think that TCP might work. Howe...

Development boards: current consumption during Deep Sleep

Hello! I am currently working on a project that needs to run on a battery for long time. Some sort of data-logger for vibrations. I intend to keep in deep sleep the main core of the ESP32 and wake it up with the help of ULP co-processor from time to time when a change in the magnetic field is detect...

Re: Higher current consumption (100uA) in Deep Sleep on ESP32-WROOM-32D

Hi marekg,

I am stuck with the same question here.
I am actually consuming around 140uA when in Deep Sleep.
However, I set up the wake-up to be triggered by RTC_GPIO.

Any suggestion about how to lower the power consumption?

Thanks :)

Re: Connection time, MQTT connect time, and current draw?

Hi Brolly!

I have your same timing here.
Did you find any solution to shorten the MQTT connection time?

Regards :)

Real-time data streaming over WiFi

Dear Forum, I am trying to understand what is the most effective way to stream data from an ESP32 node via WiFi to my PC. Let me shortly describe the application that I am working on. I would like to setup a wireless IMU node based on ESP32 and the MPU6050 [https://www.invensense.com/products/motion...
