IoTool:Network & IoT Debugger

Do you need to test a field sensor, send a Modbus command to a PLC, or monitor an MQTT broker, but your laptop isn't nearby? IoTool: Network & IoT Debugger turns your smartphone into an advanced communication terminal, the ultimate digital Swiss Army knife for hardware and network infrastructure professionals.
Developed specifically for system integrators, engineers, and firmware developers, this application unifies over 10 standard protocols into a single, clean, and professional interface. No more fragmented apps: you get full control of edge computing right in your pocket.
MAIN FEATURES BY PROTOCOL
Raw & Web Protocols
• TCP & UDP: Client and Server modes for sending and receiving raw data. Test latency, send custom payloads, and monitor datagrams.
• HTTP / REST: Test APIs, webhooks, and local servers by managing methods (GET, POST, PUT, DELETE) and analyzing responses.
• WebSocket (WS): Full-duplex debugger to test continuous data streams and real-time web interfaces.
IoT & Industrial Automation
• MQTT & MQTT-SN: A comprehensive MQTT client to inspect topics, publish commands, and monitor telemetry. Full support for sensor networks (SN).
• Modbus TCP: Essential diagnostic tool to interact with PLCs, inverters, and industrial machinery. Read and write holding registers accurately.
• CoAP: Test constrained devices (M2M) with the next-generation IoT standard protocol.
Bluetooth & Local Connectivity
• BLE Scanner & Client: Scan for Bluetooth Low Energy devices, explore GATT services, and interact with characteristics (Read/Write/Notify).
• Bluetooth Classic (SPP): Serial terminal emulator to test legacy modules (e.g., HC-05) and custom boards.
• LAN Scanner: Discover connected devices on your local network and quickly identify assigned IP addresses.
• UPnP / SSDP: Discovery tool to quickly identify smart devices and compatible routers within the subnet.
• Wake on LAN (WoL): Remotely power on servers and workstations by sending targeted Magic Packets.
ADVANCED CAPABILITIES
• Multiple payload formats supported: HEX (Hexadecimal), Text (UTF-8), and Decimal.
• UI optimized to reduce taps during repetitive field operations.
• Clear logs to analyze incoming and outgoing packets (RX/TX) effortlessly.
WHO IS THIS APP FOR?
• IoT Developers: To debug firmware on ESP32, Arduino, Raspberry Pi, or custom boards.
• System Integrators & Technicians: For commissioning home automation, HVAC, or industrial machinery via Modbus TCP.
• Network Engineers: For packet testing and verifying routing policies (TCP/UDP) on the go.
• Makers & Students: To carry a complete networking lab in their pocket.
Manage infrastructure, streamline your workflow, and reduce diagnostic time with a network tool built by professionals for professionals.
