I've used an AI Thinker ESP32-C3M module. Ref the AI Thinker datasheet schematic it had IO8 internally pulled up to VCC as bootstrap requirement for spi boot.

You have IO8 going to the LED anode, maybe it is a bootstrap issue.

Are you sure the development board supporting the fast-charging protocols, maybe they did not contain the protocols chip. If the board does not have a battery to charge, or does not support fast charging, there would be no USB communication compliant with the fast charging protocol specification. T...

I am using an HT7333A with ESP32-C3 (have also used it with ESP32) for a project with low deep-sleep current requirements. Advantage of HT7333A is the low drop out voltage (suitable for Li-Ion batteries) and very low quiescent current ~4uA. But you have to add a large capacitor on the 3.3V line ( e....

I forget where I found this workaround for ESP32-C3 (try Googling) , but this platformio.ini works for an ESP32-C3M module. I am using a custom partitions.csv local to the project : [env:esp32c3] platform = https://github.com/platformio/platform-espressif32.git#feature/idf-master platform_packages =...

Maybe i misunderstood what you are trying to do, but I would use the 32kHz square wave output from the DS3231. You could keep a counter running at 32kHz interrupt on the ESP32 that is reset by the GPS pps signal. If it goes above the 32kHz count => gps pps signal is lost, reset counter and fire the ...

What OS are you using for access ?

As far as I know only MacOS has built in support for mDNS. For Windows you need to install Bonjour, for Ubuntu you need to install Avahi.

Plus HW PCB. I am impressed.

Thanks, but the Kicad schematic is only for documentation. It's for personal use, and was built using proto board.

ESP32 development board and INA226 sensor used to capture and record load bus voltage and load current of a Device Under Test (DUT). Meter configuration, capture and display functions are available via a web page running on a WiFi web server. https://github.com/har-in-air/ESP32_INA226_CURRENT_VOLTAG...

Hi, I only have tested transmitting from ESP32-C3 to Android app via BLE uart, not receiving. At the moment I don't have an ESP32-C3 to test with (expecting a module end of this week). This was my test code ... #include <Arduino.h> #include <NimBLEDevice.h> #include "esp_gap_ble_api.h" #include "esp...

Never mind, i found the answer :
1. call NimBLEDevice::set_MTU(size) after ::init
2. in receiving BLE app, set same MTU size
