Re: Transmit 10kBytes data using BLE - SERIAL

SSP is only for Bluetooth classic

I need Bluetooth BLE

I'll thake a look to BLE "long reads" and "long writes" but if someone can give me more ideas you are welcome!

Transmit 10kBytes data using BLE - SERIAL

Hi at all, I need to transfer max 10kBytes of data from / to (bidirectional way) an ESP-32 and another ESP-32 (or a phone if this is simpler) using BLE. The idea si to have one ESP-32 as a peripheral and another ESP-32 as central (or a phone application) that transmit some data (max 10k) to another ...

Run ESP32 WORM without freertos

Is freertos necessary to run a program with ESP32? Is it necessary or optional? Why this question? Because - I need to develop a single thread application first - I need to optimize the ram since I need to write an alghoritm that use a lot of ram - I found that FreeRTOS are not able to offer me the ...

Re: Generate an arbitrary function by DAC

I guess that ESP32 is not fast enought to process digital audio and generate enought fast signal... Is it true?

Do you have other arduino/raspberry pi - like boards that you can advice for my project?

Thanks

Generate an arbitrary function by DAC

Hello, I would like to make a small project (a function generator) in wich the final goal is to generate an arbitrary function regulated form some setting. My aims is to imitate as much as possible the functions generated from this software below WHITHOUT GUI https://i.ibb.co/VHdt4mq/Function-Gener...
