Re: UART Communication problems at 921600

Hi LukeSkyWire, The UART baud rate is an integer divider from the APB clock frequency (80MHz)[*] times 16, so 941176 is the closest evenly divisible rate. You could also try 1 megabaud (1000000, a very easy value to divide to) and see how this works. How is your analog signal integrity? 1MHz is gett...

Re: Connecting 2 ESP32s as master/slave devices

If you specifically want a wireless point to point link, you may want to look into ESP-NOW: https://esp-idf.readthedocs.io/en/latest/api-reference/wifi/esp_now.html But as John A says, it's possible for two ESP32s to talk to each other via a large number of methods. (PS: I've renamed your thread fro...

Re: EN pin and RC circuit question

The power is coming from a bench top power supply... Now, I am testing another ESP32 module and the behaviour is the same... it doesnt start What else do you have at the module end? ie is there sufficient capacitance on the power pins near the module? Is the 3.3V coming directly from the bench supp...

Re: Preview release: CMake-based build system for ESP-IDF

So, hopefully there will be a period of time where we can still use the latest ESP-IDF updates without forcing us to move to cmake. And, hopefully you will have all of the bugs worked out of the cmake system before dropping support for the pure GNU make system. That way we never have a period where...

Re: Preview release: CMake-based build system for ESP-IDF

I use this with Clion and it works great, but I would like also to be able to use Arduino as a component, but there is no Branche for this of any guide I can find. So my questions is if this is possible and if yes, how to install it ? I've just written a component CMakeLists.txt file for arduino-es...

Re: EN pin and RC circuit question

Hi Chris,

What's the power source for the 3.3V line? Is it possible that it ramps up very slowly, or is unstable?

Re: How to force a CPU reset?

What ESP-IDF version are you each using? (if using Arduino or something else with its own i2c libraries, please mention this.) In recent ESP-IDF master branch, a change was added to always reset peripherals on startup: https://github.com/espressif/esp-idf/commit/ef39c09bc12206cb68816c7660c7641dd21df...

Re: Slow WiFi after migrating from ESP8266

Hi sorenhl,

200ms is indeed very high latency! Are you able to show us the TCP server code you're running?

Re: Bootloader and NVS

LI'd like to be able to not only force a boot from the factory partition, but also either erase the NVS or set a parameter in NVS so the app can make sure it goes back to default settings. So my question is 1) does this GPIO factory boot thing work? and 2) can I access the NVS api from the bootload...
