Re: How to install old idf version ?

Howdy, This may be a complete red-herring ... but I wanted to check that you understand the distinction between releases and master. As I understand it, the "master" on Github is the continually evolving "best so far" of the ESP-IDF code base. Things may break and stability may not be perfect. Relea...

Re: Eclipse C++ Build using Kolban's guide

I too had problems working with Eclipse Oxygen. However, I recently moved to the now generally available Eclipse Photon and all seems to work well again.

Re: Cannot run app on ESP32 from an external battery

If it were me, I'd attach an external UART->USB connector to the RX and TX pins of the ESP32 and see what the console is saying during boot.

Re: Connecting ESP32S with IOT relay Baord

For an off the shelf product like this, I am imagining that the provider has written some software that runs on the on-board MCU. I would also imagine that the vendor has supplied documentation on how to interface with the board from a variety of sources. Are there more details of the problems/puzzl...

[Answered]: JWT component for ESP-IDF (JSON Web Tokens)

When using certain cloud IoT services such as Google Cloud Platform (GCP) we have to authenticate with the cloud by providing a JSON Web Token (JWT) ... see: https://jwt.io/ While there are many libraries available, the number of such libraries for C/C++ is relatively low. I had a quick look through...

Re: mg_broadcast not working

I had a google on mg_broadcast and esp32 as search terms and there appears to be a number of stories related to that. Have you performed a similar search? Understand that the mg_broadcast capability is part of the Mongoose libraries and is not really related to the Espressif/ESP-IDF code bases. Obvi...

Re: Program Flow and timing

I for one am very interested in the story that setting the GPIO level high before the inner loop doesn't set the output signal high but the same code in the inner loop does. If it were me, I'd try writing the same app in ESP-IDF and see if the scenario changes. That will tell us if we are looking at...

Re: What's the best method of communication for my project

If there were some challenges in connecting an ESP32 using both WiFi and BLE at the same time, based on your story, you could choose one of those technologies and use it for all your communications. For example, if you choose WiFi between your phone and master, then you could use WiFi between master...
