Re: OLED display refresh unsuccessful - is it a task problem?

Hi, I implemented a separate "UI Task" that checks frequently for new queue messages and it apparently works quite well. I haven't had any of these fragments anymore.

OLED display refresh unsuccessful - is it a task problem?

Hi, I'm currently working on a small project where I use an ESP32 as a webserver and have a SSD1306 OLED display attached to it using the Adafruit SSD1306 library (via platform io). The screen is supposed to show some information, like the device's name, the IP and a little icon indicating if a clie...

Re: Different results of same code in esp-idf and normal c++

This is local variable, which does not exists outside convertUUID() function. It will be randomly overwritten: https://github.com/tagtraeumer/esp-idf-cpp-test/blob/main/esp_test/main/ble.cpp#L40 Hi, yeah maybe this method doesn't look good right now I was just kind of preparing it to use it for mor...

Re: Different results of same code in esp-idf and normal c++

Hi, i didnt check all your code, but after quick look at it i see this, maybe not an issue, but should help you a bit with debugging: s_print("%i", test->value[i]); With that code you will print decimal values, but UUIDs are in hex, so 8d == 141 and so on. you can change it to something like this: ...

Different results of same code in esp-idf and normal c++

Good Day! First of all , I'm quite new to c++ programming, I only started last year with lots of inactive periods in between. I already implemented a bunch of features for my ESP32 but all based on the arduino framework (platformio). Now I'm trying to reimplement one of my programs to ESP-IDF and th...

Re: How to know if ESP wroom 32 is broken?

Hello, I finally managed to go deeper into the investigation and all the pins reacted the way you were describing.

Hi! I wonder how i can easily recognize, whether a ESP 32 is broken or not. Here's my current situation. I've been playing around with several ESP 32 development boards in the past few months and prototyped an application on breadboards using either the esp doit devkit v1 or the az-delivery dev boar...
