ESP32-Based IoT Gateway Development

The ESP32 is an ideal chipset for compact connectivity gates since it provides integrated wireless connectivity, embedded processing, and economical hardware.

Adequate Infosoft produces connectivity gates based on different ESP32 families based on the specifications.

We can develop solutions based on:

Depending on the device, the gate can provide Wi-Fi connectivity, Bluetooth/BLE connectivity, Thread, Zigbee connectivity, USB, GPIO, SPI, I2C, UART, and other interfaces provided by the platform and system's architecture.

Devices based on the ESP32 chipset can be used in various applications such as smart devices, building automation, sensor networks, energy monitoring, asset tracking, consumer IoT, industrial monitoring, and compact devices.

STM32-Based IoT Gateway Development

The STM32 microcontroller family offers many capabilities from the processing and memory to peripheral options, power management, and connectivity features.

Adequate Infosoft specializes in the development of IoT gateways based on STM32 microcontrollers, which can be used in numerous scenarios requiring real-time performance, industrial-level communications, low power consumption, and efficient embedded processes.

Our team has experience with STM32 families such as:

The appropriate STM32 platform can be selected based on processing requirements, memory, peripheral availability, connectivity, power consumption, security, and product cost.

Our IoT Gateway Development Services

Adequate Infosoft is a provider of comprehensive IoT gateway development services for companies that create new connected devices or upgrade their current gateway solutions.

IoT Gateway PCB Design

An IoT gateway should have a robust hardware setup that enables the use of multiple channels of communication while ensuring uninterrupted operation.

Adequate Infosoft provides complete PCB development services including:

Our hardware engineers collaborate with firmware developers to guarantee that the PCB structure takes into account all necessary drivers, communication protocols, processing capabilities, and future product needs.

Embedded Firmware Development

The firmware connects the hardware interfaces of the gateway and performs the necessary communication and data processing processes. The company creates embedded firmware for the ESP32 and STM32 platforms using the right development environments and frameworks.

Firmware functionality can include:

Firmware can be designed for real-time operation and optimized for memory, CPU utilization, power consumption, and reliability.

Industrial IoT Gateway Development

Gateways imply connecting old equipment with modern cloud services and enterprise solutions in industrial domains.

We can build IoT gateways used in industry that communicate with numerous industrial devices including sensors, controllers, PLCs, machines, etc.

Depending on the application, gateway protocols can include:

The gateway can collect industrial data, convert protocols, filter information, buffer data, and forward selected information to higher-level systems.

MQTT IoT Gateway Development

MQTT is widely used for lightweight IoT communication, MQTT-based gateway communication for sending device data to cloud platforms, IoT brokers, or enterprise systems.

The gateway can support project-specific:

MQTT can be combined with local protocols such as Modbus, CAN, UART, BLE, or proprietary interfaces to create a bridge between field devices and cloud services.

Protocol Conversion Gateway

Many organizations operate equipment using different communication technologies.

An IoT gateway can act as a protocol bridge between these systems.

For example:

RS-485 / Modbus → ESP32/STM32 Gateway → MQTT → Cloud

or:

CAN → STM32 → Ethernet → Backend API.

Adequate Infosoft can develop the required protocol conversion, message parsing, data mapping, validation, buffering, and communication logic.

This enables existing equipment to become connected without replacing every legacy device.

Creating BLE and Wi-Fi Gateways

Gateways based on ESP32 technology are very effective in collecting information from Bluetooth Low Energy equipment close by, and then sending that information on via Wi-Fi or Etherval.

Gateway functionality can be developed for the following:

The gateway is capable of searching for the appropriate devices, connecting with them, reading their specifications, processing their details, and sending relevant information either locally or to cloud technology.

Cellular IoT Gateway Development

In the case of deployments with no reliable Wi-Fi or wired internet, cellular connectivity can be integrated into IoT systems.

Depending on the product requirements, the gateway can communicate using cellular technologies, sending information to the backend or cloud services.

Some possible applications are:

We can integrate cellular modules, SIM/eSIM workflows, network management, connection recovery, and safe cloud communication as needed.

Edge Computing and Local Data Processing

Not all raw readings from sensors need to be sent to cloud storage by the portal of IoT. Adequate Infosoft can equip the portal with techniques for edge computing.

The portal can carry out the following processes:

This will contribute to decreasing traffic on the network, minimizing delay, and enabling essential functions to be carried out even when there is no access to the cloud.

Offline Data Buffering

Good IoT gateways should be capable of dealing with disrupted connectivity. Local buffering technology can therefore be implemented, allowing the gateway to store data temporarily in the event that it cannot access the cloud/backend.

Once connectivity has been restored, the gateway can retrieve the buffered information in accordance with the data delivery requirements of a project.

The storage can be based either on internal flash memory, external flash memory, SD cards, or other technologies suitable for storage purposes.

OTA Firmware Upgrades

Connected gateways may need to be upgraded with firmware remotely through OTA technology to rectify errors, provide better capabilities, or potentiate new functions.

Adequate Infosoft has expertise in devising OTA upgrading systems for ESP32 and STM32 based systems according to selected technology stack.

OTA capabilities include:

Through use of OTA we can decrease the necessity for visited servicing of deployed gateways.

IoT Gateway Cloud Integration

Adequate Infosoft can connect gateways with cloud platforms and custom backend systems.

A typical architecture may look like:

Sensors / Machines → ESP32/STM32 Gateway → Secure Network → Cloud API / MQTT Broker → Backend → Database → Dashboard / Mobile App

Our backend and cloud engineers can develop the supporting infrastructure required for device communication and management.

Backend and API development

The backend team creates the APIs and services of connected gateway ecosystems.

Some of the backend capabilities consist of:

APIs may be merged with existing enterprise software and third-party software.
