Firmware for ESP32 based IoT Gateway

Hi, I have more than 8 years of experience in embedded design and development. I have expertise in IoT Products development using WiFi, GSM, GPS, RF, ZigBee, LTE etc. I have hands on experience in firmware development using ESP32 with different peripherals, sensors, displays, motors with drivers, batteries etc. I have also interfaces 3G/4G module with ESP32 module for sending data to cloud using http, https, udp and mqtt etc. Furthermore I have ESP32 Dev kits to test firmware. I am located in Ahmedabad, Gujarat. So it would be good as per your requirements. Let’s discuss about your complete requirements. Thanks&Regards.

Hello, I'm basically from Gujarat. I have experience of developing firmware for ESP32 using ESP-IDF SDK as well as Arduino. Also I have worked with WiFi, MODBUS communication, RS485/RS232, CAN, GSM Modem Communications, SD card storage. I can help you for your development. We can discuss in detail over chat.

We are embedded systems developer based in Bangalore, having developed IoT Solutions buit around ESP32, Onion Omega2, Pic Series processor and more. We also may have a ready solution to meet your requirements Can we discuss. We can share more details about work over chat Thanks

Hi I am an expert with more then 6 years of experience in embedded systems, Iot, automation, pcb design and dovelopment and prototyping. I have hands on experience in arduino, esp32, pic, arm, raspberry pi and other mcu. Yes i have previously experience in diffrent products. I hope we are start working together and our working relationship is for long term. Thanks

Hey There, We Industrial Professionals with having more than 5 years of wide experiences in Robotics with enabled IoT, various Electronic circuitry (Low and High Power Electronic circuits), Comm. (BLE, RF Modules, WiFi Modules, GSM/GPRS, Zigbee etc.) with Micro-Controllers like Atmega Series, Arm Series, ESP Series. Most of our projects were Automation with IoT Enabled system with monitoring providing on Open Source and Private Web Servers. We've worked with Various ESP series with different Wireless protocols like ESP-NOW and ESP-Mesh for establishing comm. in local with which are out of ranged devices. We need to modify library when the device is out or range while moving it should transfer using Non-WiFi Protocol and When it's in WiFi range, It'll be rejoined with WiFi again (As a backup, We've added storage device with system like SD Card (normally used) if we missed out any Data during functionalities)to provide seem less Cloud connection with device. From our experience with different modification with libraries, We can help achieve you project goal, To make device an industry usable! Hope we match up to your project requirements. Currently we also have an active startup that has served solar industry by its innovation in IoT & Automation in Area like Robotics and various Cloud Platform. Start Chat with us to discuss further about your project for Quick and reliably easy solution. Regards Team Light Bulb. **Prices are negotiable** **Project Duration is Negotiable**

I am an Electronics design engineer with More than 4 Years of Experience. I have design expertise in Embedded systems, Schematic design, PCB layout ,Hardware Debugging and hardware prototyping. I also have experience in designing Internet of Things,and Circuit design. Please Put message so we can discuss more in detail.

Hello, Your project is interesting to work on. Note: Please tell me more about the project. I have relevant experience working on development boards like Raspberry PI, Arduino, Rock64. Projects on these boards include technologies like Database: Mysql, MongoDB Language: Python Framework: Flask (web python framework) Front-end: Html, CSS, javascript, bootstrap Worked on sensors like Soil Moisture, Temperature, GPS, and other components like GSM and ZigBee for creating Mesh Network on Raspberry PI. Projects finished: Geo Server on Raspberry Pi Wind Mill - Big Data moving average on Raspberry Pi Smart Irrigation - Raspberry Pi and ZigBee RFID Tag system - Arduino GPS and GSM solution - Raspberry Pi Stepper motor with leadshine driver Changing boot order and flashing spi memory (R&D project for a client) - Rock64 Access Control System (Dual Mode - AI on Timestamp between RFID and Camera) Looking forward to work on this exciting project. Let's connect and have a brief discussion about your requirements so even I can give you some inputs from my experience. Waiting for further discussion. Regards, Kahan C.

hello sir, I am electronic engineer having 8 years of experience in embedded programming and pcb designing. I have worked with esp 32 module and development some automation based project with that chip. I have read your project discription and sure I can do this . please message me for further discussion. Thanks and regards Umesh Mishra

Hands on experience on similar project and technologies. For example: C programming : 3 years IoT Project : 2 years Protocols : MQTT, Modbus, TCP/IP

I have experience with arduino, ESP32 and real time data capturing over wired and wifi network for the application used in water level controller. After going through your project details you are looking for a robust backend code for data acquisition for a particular device on future future services and applications can be built up.I can develop such a strong foundation for your device and would be glad to this further.I am based out of Hyderabad,India

Hi, This is Pratheek from Bangalore. I can help you build your IoT Gateway. I have experience in hardware circuit designing and embedded firmware development. I have previously built many sensor nodes and IoT gateways for specific applications. This experience will help me develop your Universal Gateway better and faster. I will help you build a cost effect IoT Gateway with Wifi, Ethernet, RS485 and 4G(2G is already being phased out so I do not recommend it). I will also build a universal flexible firmware that will send these data to cloud. I guess you are looking to send sensor data to the cloud. I will design the hardware to accept multiple standard sensor inputs - digital, analog, I2C, SPI, 0-20ma, etc. I will provide an hardware in which you can also configure the cloud required for project - AWS, Google Cloud, Azure, or even your custom server. I will also get your hardware fabricated and delivered to you. I will be your one point of contact for all your projects. You will not have to go around searching for multiple vendors to get your product ready. This way you can concentrate on your core business and not on getting the gateway ready! This way your investment will be one time and you can use the same gateway for multiple projects. Contact me and we will discuss and start the project immediately!
