I need to Pass BLE280 sensor readings (Temperature, Humidity, Pressure) to Arduino Nano and further via Modbus RTU RS485 (I use SCM TTL interface module to connect to a PLC that is acting like a Modbus Master ). The readings from the BME280 are float numbers and thus the Holding registers must be accordingly.
I'm working on an academic project where I need to make an automatic connection between a BLE breathalyzer device with custom features. My goal is to make the ESP32 in client mode look for the device's Mac and make the automatic connection, I can make this connection normally through the ble Scan application and bluetooth terminal software, for more details I'm available.
I have an Esp8266 D1 Mini Wemos Wifi Module card and a SSD1306 oled display module for wemos d1 mini 0.66" inches 64x48 I have a ticker to display the Bitcoin price on this screen that works very well by collecting the value from the Coindesk API (but only limited to Bitcoin. The internet connection is made through Wifi defined in the source code, that is, whenever a network changes I have to load the updated code on ESP8266 Changes I want: 1) Inform the Wifi data by cell phone through a screen connected to Esp8266 instead of defining the username and password by the source code. 2) On the same cell phone screen, select which currencies should appear on the ESP8266 screen: Bitcoin, Ethereum, Doge, EOS, Tron, Litecoin, BNB, Cardano, Solana, Monero e Stelar (to get these values y...
i am working on Lora Ra-02 SX1278 with Arduino with dht11 sensor i facing some issue with receiver side. sender side ok sending correctly in serial monitor but not in receiver so if u r interested to help me plz check attach files then bid
I'll try to summarize as much as possible what I want and if you have any questions just ask me. I would like to develop a hardware, basically I want to create a gas sensor using an Esp32. This would be the first part of the project, the second would be just an app to visualize this data, alerts in case of leakage, that would be very simple. I want to solve is precisely to make it commercial, for example: To be able to develop a system that is multi-user, where the customer who buys my gas alert system can register this sensor in the app and have access the aforementioned information. Summarizing what it would be: Develop pcb for this gas sensor system, app for the customer to register the device and the "backend" so that this idea of several users on the platform works...
Hello, I need to design a software that can program an STM32 microcontroller using function block diagram (similar to a PLC) and is capable of storing data on a cloud platform. The device will have 4G module/ Ethernet module to upload data.
I wa t 10 inch display which can becdrifen by aurduino or rasberry pi. There will be 4 digital input , based on which few graphics to be changed and audio lre recorded sound to be announced.
Summary: Off the shelf micro based control unit using Arduino, etc. Unit takes 2 pulse inputs and interprets to speed, these are 5 volt PNP inputs. Unit has multiple relay outputs for alarms, 4-20 ma analog output, serial output (fixed length ASCII), Ethernet Modbus and Profibus interfaces (slave). The unit has no keypad nor display, programming wil be via bluetooth running an app on IPhone and Android devices. App writing is required. Unit has 2 modes of operation. Stand alone single pulse processing and differential detecting from 2 pulse inputs. Thru Hole and SMT, coding, testing and all drawings and source code.
C, C++ developer required to write control and telemetry software based on ESP32 or STM32 microcontroller. 1. The device must connect to the vending machine using the MDB version 4.2 protocol in SLAVE mode and present itself as a bank card reader. 2. The device must connect to the bank payment terminal using the MDB version 4.2 protocol in the MASTER mode, and present itself as a vending machine. 3. An example of the operation of the device: - the vending machine makes a payment request to the device - the device, depending on the business logic, makes a request for payment to the payment terminal or immediately responds to the vending machine with a refusal. - if there was a request for payment to the terminal, the device waits for a response and, depending on the business ...
Hello, we had to change our original project, so now we are going to order something a little different. We need a PCB so that it can control an electropump, a solenoid, a safety float and, in addition, it has a safety system to prevent the opening of the box that contains the pcb, that is, if someone opens the box, I want Let me know via wifi or via Lte. It doesn't matter what everything is developed with, it can be arduino or whatever.
I have a simple teensy sketch. I have supporting schematic and hardware. I have compiled to best of my knowledge but I am doing something wrong. I am trying to put together but somehow cannot seem to get it working. I would like someone to guide / assist me in what I need to do to get the project working. I would also like someone to modify the code to port from a teensy to esp32/8266. For a professional this will be easy work. For me I don’t have the attention span. I am confident with soldering circuitry and simple code. But I am not a c+ nor a micropython expert. So I require the services of someone who is competent in arduino, teensy, c++, python and circuitry / pcb. Also have another project looking to reverse engineer a pcb where to the successful applicant will receive a n...
I need to send HTTP request with Quectel 5G Module RG502Q. The module is connected to ESP32 using serial port and to be controlled using AT commands.
We wish to build up on and use one of these existing projects. This is a basic 'credit' management system for users, where they swipe a card and credits are taken off, it is logged and there credit total is adjusted. BASIC outline of what we are wanting to achieve. User will - swipe a card - handshake with server - check if user has credits available IF ---- YES - Output a signal on the one of the ESPXX spare pins momentarily. - Reduce users 'rolling credit' on 'server', saving ID of ESPXX device. ---- NO - Alert user with message on screen to see an 'ADMIN'. On the links above, software / programming / general setup etc exists. So most of the 'hard work', has been done. Modification of front end and back end as required to dis...
I need a simple audio hardware design/schematic to manage 8 zones of already wired left/right speakers in my home and two out by the pool. I think I would like a page on my iPad and iPhone which gives me all options of what music I wish to stream, (only one stream for all 8 zones at a time). Off/on for each zone, and volume. Do I simply need an app, a good amplifier, solid wifi connection, smart speaker selector…? No problem if this isn’t the type work you do. Thanks just the same, Steve

In this project , I use tracking shield sim 900 from Rhydoz lab which is a development board designed for tracking .It consists of GPS/GSM/GPRS in it .The main idea is to detect location and interface it with google maps so that we get location details of a vehicle to which it is set ,the location is sent as message to the mobile number programmed .But the problem is that I'm getting latitude and longitude but I'm not getting message to the prgrammed mobile number nor AT commands is working .so i need help in this project who have a good knowledge in embedded c
My project uses a react native app to communicate with an ESP32 via BLE. It works fine, however, when I try to send a 32 character long string encoded as base64, the ESP32 only receives the first 20 characters.
