Здравствуйте, Андрий. Надеюсь у вас всё хорошо. У нас есть задание для ESP32. Необходимо сделать АР на котором будут DHCP и DNS серверы, и функция маршрутизации пакетов между Wi-Fi Ethernet портами. Эти функции есть в отдельных примерах ESP-IDF, а нам нужно объединить их в одной программе. Сколько времени вам понадобится, чтобы реализовать это и во сколько вы оцениваете эту работу?

Добрый вечер Андрей, я студент электроники и мне нужна помощь с разработкой печатной платы и firmware. Плата должна иметь микрофон чтобы читать частоту звука (0-40khz) и с помощью модуля ESP32 показывать её на телефон через bluetooth. Должна также имеется возможность передачи данных сквозь API.

Здравствуйте, Viacheslav T.! Я обратил внимание на ваш профиль и хотел бы предложить вам свой проект. Есть ESP32 DEVKIT и I2S микрофон. Нужно, чтобы по нажатию кнопки начиналась запись, по второму нажатию останавливалась и файл отправлялся по интернету. Стек технологий на твое усмотрение, но чтобы была возможность получать эти записи по интернету и работала более менее стабильно (а не по локальной сети). Никаких больше специфических требований нет. Можем связаться в телеграмм - @kishovRasul

Необходимо разработать устройство на основе модуля ESP8266 Либо ESP32, которое будет выполнять сбор данных с датчика расхода воды (импульсный выход) и датчика TDS (аналоговый выход), и дальнейшую передачу этих данных на сервер (MySQL, MQTT либо другое). Кроме того требуется передавать на сервер некоторые дополнительные технические параметры (MAC-адресс модуля, IP-адресс, имя WIFI сети, пароль используемой WIFI сети, напряжение питания, напряжение батареи, температура модуля). В разработку устройства входит: - выбор корпуса (желательно из доступных на рынке Украины); - разработка печатной платы, либо выбор готовых решений на основе предложенных модулей; - разработка програмной части (прошивки) модуля ESP; - разработка приложения для Android/IOS, либо веб версии. - изготовление тесто...

Hi, I need to program the LILYgo 7000G board to communicate via MQTT via LTE and wifi. It is also required to read the GPS position. Regarding the power part, it is necessary that the board goes into deep sleep consuming in general less than 50 ua/hour. To achieve that it should be possible to turn off the SIM7000G via software through the ESP32 and put the ESP32 into deep sleep. It would be necessary to see the rest of the electronic components and their power consumption.

I'm looking to build a charging device that uses the ESP32 micro-controller powered by a Li-ion (for example battery for a FireBeetle ESP32 battery port) or Li-Po battery which will be charged by a solar panel. At the same time (while charging) the ESP32 will be still working for the purposes it has been installed for (it will be working for 10 hours, between 09:00 and 19:00, so actually working only in the charging hours). Of course it should have protection when fully charged, to stop charging, etc etc. Please, only for hardware designers who have already made something like that. The other offers will be dismissed.

Hi, I have a small sailing boat which is moored in the middle of an harbour. I would like to monitor using GPRS 2G network (via Telegram) or SMS the follow...itens: -gps position. -temperature and humidity using the Dht11 sensor. -battery voltage. -water on the bilges.

Connect an lcd display to a esp32, and a vs1053 board along with a lithium battery for a project. I also need appropiate code so that the esp32 can communicate with the display properly, and a system by which the vs1053 can send audio to an app. The app will analyze the audio and send back results to the esp32 and the display more details can be given. I can provide and send materials for the project. I already have a display, a battery, the esp32, the vs1053, and some connectors. Anything else I can buy, as long as it's relatively inexpensive. All I need is a functioning prototype and a possible cad design of the final device.

Hello, I need an Embedded software developer on the ESP32 to write an Ethernet Library, based on the official esp32-arduino Ethernet Library, to support for a custom RF module.

The aim of the project is to control the barrier mechanism at the entrance& exit gates of the sparking...the parking slot through a mobile app GUI like a flutter. The reason for that is to make a parking more smarter by pre-booking for the app, navigation helps them to find where they parked and payment. Controlling the barrier since uncertain behaviors can happen like leaving the car all day at the slot which is annoying others. Required for me to have the hardware: A microcontroller such as ESP32 / Arduino / servo motors / Leds / LCD and a space for a parking slot. Software: A GUI with features such as ( booking own slot in real-time, Navigation, and payment, and might more) I would like to hear from you very soon.

I have implemented a simple websocket echo server and a corresponding client that runs on separate esp32s3’s and communicate via wifi and it works. However the performance is very poor (~ 500ms for a roundtrip) so what I need is a optimization giving ~50ms roundtrip times. I have also implemented a python client and tested it against the esp32 server with good results (1000 roundtrips): Number of echos over 50 millies: 999 Number of echos over 75 millies: 40 Number of echos over 100 millies: 29 Number of echos over 150 millies: 13 Number of echos over 200 millies: 8 Number of echos over 250 millies: 8 Number of echos over 300 millies: 5

we have a project where we have to download a script file (that would be run by an interpreter written within ESP32) and a json file (that would contain the data that would be downloaded into the ECU (Electronic control unit)). once these 2 files are stored in the SD card, the interpreter would have to run the script and download the content of JSON file to ECU. Candidate having extensive experience in ESP32 IDF programming, CAN communication, SD card file processing, only may apply.

...the ESP32-S3 module with a USB port for a project. The ESP32 should boot from its flash and first detect if there is a USB pendrive plugged into it. If so it should copy two files - the executable file and the .HTML file from the pendrive to its flash. Then it should reboot, obviously now ignoring the pendrive and run a HTTPs secure webserver over WiFI in AP (access point) mode. Once a user logs in, the HTML file (about 250k) is served to the user, along with the application data from a 16384 byte RAM array on the ESP32 using the Websocket API. Changes made on the webpage by the user, usually using an Android tablet, also using the WebSocket API are stored in the RAM array, and also sent over the SPI bus to the rest of the system. At powerdown, indicated o...
