First of all, please the software developers don't send me offers as my project has not so much to do with html, css, etc at this stage. So do not waste your time and my time as well, please. I am searching some hardware engineer with real experience in setting up a network of a lot of nodes (esp32 or esp32-Lora) I want to set up a network of 120 nodes in a field (open air) where the most distant nodes are around 120m from the pc. All the rest in between nodes have a distance of 3-4 meters each one of its next one. They are deployed in 4-5 lines of around 25 nodes each line. I have already set up my senders and receiver sketches (Arduino IDE). The matter is the limitation that the ESP-Now protocol sets (up to 20 nodes as I know). One solution that I thought is to mak...

Hi, We have a vibratio...dashboard. I would need someone who could help me developing a custom mesh protocol, as I want to introduce some constraints and rules. This will be a very interesting project for us to develop vibration monitoring system for industrial machines. Also experience with the followings will be very appreciated and of advantage, as this project may evolve to work together with several peripherals: - ESP32, GPS, RTC, Touch display, Compass, temperature, humidity and pressure sensors, PCB layout, (...) We will award you the project if - you are able to set up a code to communicate with system using LoRAWAN or BLE - you provide a working demonstration (in video) of the LoRaWAN Mesh network for the device. Do you agree on these terms? Thanks in advance for your...

Hello, I have a pcb with ESP32 S3 that has bluetooth capabilities. The bluetooth is acting as a server and receives connections from an iOS app and from another ESP32 S3 configured as client. Code is written in Arduino IDE. My problem is, I do not seem to have BLE 5.0 range results, the range is similar to BLE 4.0, which is around 5-10 meters. I have been doing some digging and it seems ESP32 S3 with BLE 5 has 3 types of PHYs (physical layers): 1M, 2M and Coded PHY. As far as I read, default is 1M? (which is BLE 4 range basically). My goal is to adapt my code in order to support 2M PHY (100m range or so) or even Coded PHY (500-1000m), so the BLE connection can work at more than 5-10 meters. Thank you! Marius

We are working on a ongoing project to design the ultrasonic flowmeter using Time to Digital conversion technique where we stuck in configuring the registers of IC and reading the valid data back. We are in need of expect to resolve the issue.

We have an embedded application which collects data and stores in an SD card. We would like to send the data to a server via a JSON webservice. The data can be sent as an attached file as saved to the SD card, or in JSON format as the message body. We are capable of modifying the web service according to the format of the data sent in collaboration. An example file and the current code are attached. Converting the date format in the file to yyyy-MM-dd HH:mm:ss is a nice to have.

We have an Ionic 6.0 App (with Cordova) which connects to our IoT device developed with ESP32. The app has a setup screen to send Wifi information to the ESP and it works most of the time. Right now we want to implement ESP SmartConfig features but could not find a proper ionic plugin or failed at implementing them. So we are looking to work with someone who has a history with Arduino systems and can develop the missing setup page of our app in Ionic 6.

i want to stream the video feed of esp32 cam directly to the domain name(cloud server). want we have done this in local area network (behind router) but now we want to do this in cloud.

...suppose we want 120 esp32 in a mesh structure. Every node (ESP32) has a distance of 4 meters each other. The longest distance (node) is 150 meters from our PC. The physical structure of the devices is in 4-5 lines of 25-30 nodes for example. In our PC I want to have a webpage where I can see for each node its button state: we press a momentary button in the node, the particular box (CSS) becomes green, we press again becomes red. All the senders (120 EPS32 devices-nodes) work in deep sleep mode when their button is not pressed. Even the page is closed, when we open it back again, the data is preserved (running PHP-mySQL). I want to ask if such a project is possible to be done, secondly we need a router (internet) ? Also how reliable could be? Do we need Lora or the...
