Hi. I have been trying to implement modem sleep in the ESP32-C3, more specifically for BLE, since I could not find a singular function that handles modem sleep. The current draw when modem is on, is about 80 mA, and when modem has not been turned on, the average current draw is 10 mA. So far I have ...

In that case i would suggest to open issue on github. Here is interesting issue about BLE power consumption with old esp32, but may give you some answers: https://github.com/espressif/esp-idf/issues/947 Thank you for that link, it contains a lot of useful information for me. I'll open an issue for ...

Then try to flash hello world example with deep sleep and compare current consumption. The deep sleep current is about 7uA. Light sleep current is about 120uA. However, when I turn on LPN mode in the sdkconfig, and let it automatically go to LPN mode's light sleep, it is 10mA. I do not understand t...

This is not normal for ble mesh, but it may be normal for the board you are using, assuming its devkit.

It's a custom designed PCB.

Hi.

I am developing a low power BLE mesh node using an ESP32C3. My baseline current in sleep is 10mA, which is pretty terrible for light sleep. Is it the usual sleep baseline current in an low power node? Or am I doing something wrong?

Just wanted to point out that for the ESP32-C3, it can be done by

I'm trying to make an ultra low-power passive sensor with the ESP32-C3. Getting it into deep sleep brings the current down to about 7uA. However, when the ESP resets, or boots, there is a massive 90mA spike that will most definitely make quick work of the poor CR2032 coin cell. I have a few ceramic ...

Hi. I just recently installed the ESP-IDF and used the VS-Code extension with it. I built some simple C programs, and the blinky program. All those worked perfectly. But when I built a new project with BLE GATT client as a template, it just doesn't build. I have made no changes to it whatsoever, jus...

The data transfer rate depends on the protocol used - http-udp-tcp-ftp etc. I check transfer data from sdcard on ftp, the max speed 1MByte/sec. But this also includes the reading time of the sdcard Could you perhaps show me how to do that as well? 1 MByte/s is well above what I want to achieve, so ...

Hi. I am trying to send ADC data to a webpage created on an AP generated by the ESP32 itself, using the following code: #include <Arduino.h> #include "WiFi.h" #include "ESPAsyncWebServer.h" const char *ssid = "dataAP"; const char *password = "123456789"; AsyncWebServer server(80); #define ADC_PIN 10...
