Re: cpp template using freertos and external cpp libraries

Howdy, Think of any application you write as running "within" a FreeRTOS environment by default. When the ESP32 loads (with the standard bootloader), FreeRTOS is started including the scheduler. All the FreeRTOS libraries are available to your application. By default, user code (i.e. code ...

Re: [Solved] Eclipse, C++ and the Standard Template Library

Excellent ... thanks for the response. Tips and improvements on the procedures are always welcome ... that way we can all learn from each other. I'm becoming a bigger and bigger fan of working in C++ each day. Given that (for the most part), C++ is a superset of C we can leverage our existing C skil...

Re: ESP-IDF 2.0

Howdy, Don't think of the ESP32 as desktop PC with an operating system onto which you can install upgrades and patches. Rather, think that the ESP32 runs ONLY one application at a time and that the application is a binary file which is "fixed in form" at compile time. When you run an ESP32...

Re: gattc open issue

Howdy, I'm not an expert on BLE but I'm trying to study hard. The first thing is to decode the error code which we find means ESP_GATT_ERROR (see https://github.com/espressif/esp-idf/blob/master/components/bt/bluedroid/api/include/esp_gatt_defs.h#L190) which doesn't really tell us much. So let us st...

Re: ESP32 + LP55231 IC2 gremlins

What I2C clock frequency are you using?

Looking at the data sheet, it seems that the max is 400KHz ... but that is the max. Can we try at a lower clock frequency?

[Video] ESP32 - Building a C++ Application

I've been on a kick recently working in C++ with ESP32 and am very much enjoying the pairing of the two. I've been using C++ in some of my previous videos and been seeing a number of questions on how to get a build environment going with C++. This video provides a walk through of the steps that I ch...

Re: connected wifi stations

Well hmmm .... that was harder than it should have been. From my study, I believed that the answer was the tcpip_adapter component but after a search I could'nt find any docs in the web site on that component. Has it been accidently missed from the inclusion in the web based docs? The answer to your...

Re: A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

My opinion is "yes". I use Windows 10 as my desktop OS but use VirtualBox running Ubuntu for all development for ESP32. In addition, I am of the opinion that platformio isn't ready yet for GOOD ESP-IDF platform development and am trying to see if that community is willing to work with the ...

Re: How to get the rssi from BLE scan

I'd like to second what neilyoung said ... Ive started to study platformio and think I see that it currently has limited integration with the ESP-IDF technologies. It might work fine if you are staying exclusively in an "arduino" platform but if you are working in an ESP-IDF platform, it i...
