Esp32 nvs example jobs

As discussed, please change code to work on ESP32 and add 3 features from previous project: 1. Trigger relay if no connection 2. Update over the wifi OTA 3. Static IP All features are available on first project.

I want the ESP32 to work in deep sleep mode. 1) What I want is the following: with only one momentary button (obviously this one that is connected to a gpio wake up pin) to switch between two tasks. Pressing once the momentary button to send A data (this is the task "A") and pressing again to send B data (task "B") , if press again send A data, and so on. (for example sending data to another ESP32-receiver) After the task, the ESP32 must be deep sleeping. 2) Moreover , when the ESP32 resets (lose its power supply and gets it back) I want the ESP32 to send again (without pressing the button) what it did in last time before the power cut off, for example if last time had sent the data A, before the power cut, now after...

We have a current commercial system that runs on the dsPIC33EP512GP506 (Ansi C code) which is currently unavailable. Also we want to take advantage for future development of the capabilities of the ESP32 S3. This project has 3 key elements: 1) Redesign the current circuit board to be exactly the same size, same plugs, same mounting holes and peripherals but change the microprocessor. Will require new schematic and gerber files 2) Migrate the C code especially device drivers to run efficiently on the ESP32 S3 ensuring software timers work at the same speed as the current ones. 3) Build 5 prototype boards with all components to fully prove the design. We will provide 2 sets of peripherals to the freelancer. Peripherals are: 1) 4 x 16 character LCD (including back ligh...

Hi there, I have an ESP32 with a simple arduino code that exposes two characteristics, one push notification and one read/write characteristic via BLE, see attached. I need a React native app (Visual studio code with Expo) that via a button press scans for this device and connects to it. Once connected, it should display the value notified from characteristic 1 in a simple text and continously update it when a new value is received. It also needs a button that writes '0' (zero) back to the read / write characteristic. Thanks! Marc

I am looking for an experienced developer to help debug an Arduino code. I am interfacing a 3electrode sensor with LMP91000 AFE then getting the readings via the Analog port of ESP32. The readings so far are not satisfactory/accurate. I am attaching 4 files which may give you an idea of the issue.

...to create a mesh of more than 100 ESP32 nodes devices each of which is connected to load cell using HX711, the data of these nodes are sent to AWS cloud using MQTT protocol using ESP32 root node using local WIFI router. You should write the firmware for ESP32 parent node device which communicates with HX711 (24bit ADC convertor) which is further connected to a load cell. This node firmware should include following 1) Auto Calibrate functionality 2) Tare functionality 3) Minimum Threshold value functionality Each ESP32 parent node device reads the data from HX711 after every “X” (5/10/15/20/30) second and if the difference between the present value and the previous reading value is greater than minimum threshold value then the Data is sent to ano...

I need some help with CCtalk and to create an interface for a coinchanger. This is a project that is very close to what I want to do: It does not have to be arduino. ESP32 is an aternative. PIC another. I have some Arduino skills and are able to create the setup in Sweden. Some of the development will be thru TeamViewer. You need to have a CCtalk host to be able to verify your work. I will copy your work and apply it to a Comestero coinchanger. The task is to have 4 buttons. * 10 SEK * 20 SEK * 50 SEK * 100 SEK (option is 5 buttons and 200 SEK) When a button is pressed the coin value is sent to the Comestero coinchanger and 20SEK = 2 tokens from the coinchanger. The buttons will then be replaced

I write what I will do: I'm going to attach a button. When I press the button once, it will send data a to the serial port, and when I press it again, it will send data b. It will wait in sleep mode when the button is not pressed. When the power goes out and comes back on, it will repeat the last task and go to sleep mode.

Hi, i am having a partially completed schematics based on esp32. Take a look at the schematics i have attached. I want the schematics to be completed and the board to be routed into the similar shape as attached in the reference image. Important: The design might be complex for you feel lack of confidence and knowledge in designing this then don't apply. A) Don't apply without reading/seeing any of the content here and also don't apply if you don't know calculations as the design requires some calculations B) only apply if you know to implement ESD protection using TVs diodes, filter design and impedence matching stuffs. C)The project is time critical so,if you can't deliver within few days then don't apply. D) Creation of footprint and schematic...

I need something to help my validate an object data (required fields, valid values). It will run in the browser using <script> tag, so cant use npm/typescript based validators. E.g: const myScheme = { field1: "text", obj : { field2: "number" } } const objExample : {} Now code something that will validate that is text, and exists and numeric. And if validation is false, tell me why.. I thought of using: Buy i'm open to suggestions

First step: We need an AI that is able to detect elephant rumbles from jungle recordings. Additionally: The...As a non profit organization our budget is limited. Hope you can consider that as well :) At the end (Not part of your job for now): The trained model should run on a solar powered microcontroller (ESP32) as an elephant detector while it is constantly listening in the jungle with a connected microphone. These detectors will be able to spot elephants before they reach a farm or village and warn rangers in that area who can deal with that situation. This will prevent human-elephant-conflict. As far as i know only Tensorflow (With Tesnorflow Lite) or PyTorch (with TinyML)are able to run on a ESP32. Which should be considered. If you have any further questions. Feel f...

The project refers to an intergrated automated beer dispensing system. Each shop is going to have a quantity of beer dispensers which will vary ( between 1 and 10 ). Each new customer will have the ability to add his personal info and details in one database which will be on the main computer – server. Then, he will get his personal RFID card which will belong to his account. Each customer will have the ability to add credits to his account by paying via cash on the cashier, or card or paypal in the future. After adding credtis to his card he will be ready to choose the beer of his preference. When he will choose the beer of his preference, he will log in to the dispenser via his RFID card and the dispenser will communicate with the main computer – server in order to get access...
