IoT Device Firmware Development
Embedded firmware in C/C++ for ESP32, STM32, and Raspberry Pi platforms. BLE, Wi-Fi, and LoRaWAN connectivity with OTA update support — devices stay current without physical access.
We connect devices, sensors, and cloud platforms into reliable IoT systems — from smart home products to industrial monitoring with 99.5%+ uptime.

Multi-sensor deployments for temperature, humidity, motion, and custom analog inputs. Edge preprocessing filters noise and reduces cloud data costs by transmitting only actionable events.
AWS IoT Core, Google Cloud IoT, and Mosquitto MQTT brokers with secure TLS connections. Message routing, device shadow state, and rules engine automation for alert triggers and downstream integrations.
Real-time web dashboards built with React and WebSocket connections showing device status, historical trends, and alert management. Role-based access for operators, managers, and administrators.
Local processing on edge gateways for latency-sensitive applications like industrial safety systems. Devices continue operating during network outages and sync data when connectivity resumes.
We evaluate sensors, microcontrollers, and communication protocols (BLE, Wi-Fi, LoRaWAN) based on range, power budget, and deployment environment.
Working prototype on breadboard or dev kit, tested in target environment. Firmware and cloud pipeline validated with 10+ devices before production scaling.
Production-grade firmware with error handling, secure boot, and OTA updates. Cloud infrastructure provisioned with monitoring, alerting, and auto-scaling.
Field deployment support, device provisioning workflows, and 24/7 cloud monitoring setup. We document maintenance procedures for your operations team.
Stack4Dev uses the following technologies for iot solutions projects — chosen for reliability, hiring availability, and long-term maintainability.
Wi-Fi and BLE connected lighting, climate, and security system with mobile app control — deployed across 500+ residential units for a US property developer.
Vibration and temperature sensors on manufacturing equipment with predictive maintenance alerts — reducing unplanned downtime by 35% for a Surat factory.
Wearable pulse oximeter and temperature patch sending data to a clinician dashboard — used by a Melbourne telehealth provider for post-discharge monitoring.
Soil moisture and weather station network with automated irrigation triggers for a Gujarat agricultural cooperative covering 200 hectares.
A property developer in the US needed connected lighting, HVAC, and security across 500+ residential units. Stack4Dev built the firmware, AWS IoT cloud pipeline, and resident mobile app — achieving 99.7% device uptime across the fleet.
Stack4Dev is an IoT development company in Surat, India, building connected device solutions for clients in manufacturing, healthcare, agriculture, and smart home sectors across India, the US, and Australia. Our firmware and cloud engineers work as one team — reducing the handoff friction common in hardware-software projects.
