via AT commands over an RS232 interface Are you using Espressif's "AT firmware" or do you (plan to) implement your own UART/"AT" protocol processing on the ESP? I've updated my post, since it was quite on point. Indeed. I've started to work at a new company that has this project, which is kind of i...

I am currently working on a project where an ESP32-WROVER module is controlled by another microcontroller, specifically an STM32G070 (with fewer capabilities and no RTOS), via AT commands over an RS232 interface. The ESP32 runs with the ESP-AT firmware. My question is related to the limitations of t...

I have just finished the electronic design of my project and would like to request a review from anyone with more experience in PCB design. It's a custom development 2-layer board based on the ESP32-S3-MINI-1 module, but it also includes some additional features: -An ICS-43434 MEMS microphone. -Wire...

Sorry if this is a necropost, but I found this thread useful, and thought I could add to the discussion. I found this to be a good reference: https://github.com/atomic14/esp32-walkie-talkie/blob/main/lib/audio_input/src/I2SMEMSSampler.cpp#L48 Here, only the lower 11 bits of the 32-bit frame are bei...

So I have a simple code to plot the INMP441 audio input into the Serial Plotter. However I find two major issues after testing the code: -The sample rate does not match with the sample rate I set in the i2s_config structure. In fact, is the half of the frequency i set up in the .sample_rate variable...

Ah, never mind. I see that your task does not contain an infinite loop. Task functions cannot just return, they either need to run forever (while(1)) or use vTaskDelete(NULL) to delete themselves.

Thanks very much for your help. I thought I replied but it seems it totally went over my head.

I changed it from 2000 to 10000 and I even tried with less. The problem wasn't solved.

I had a simple code to my project for the ESP32 that basically SCAN Wifis nad then allows you to connect to any of the networks selecting the SSID and password. Works perfectly until i decied to add a real time task that cheks every 500 ms if the connection is still active and print something (simpl...
