Device Connectivity & Gateway Software
Connect your devices to the software that needs their data. We build device servers and gateway software for message handling, local processing and cloud connections, including the behaviour needed when networks fail.
Discuss this serviceThe connection is a product feature
A device can send a valid reading and still leave the application with a problem. The message may arrive late, arrive twice or disappear during a network interruption. A connection that works once in a test is not enough for everyday use.
We review the protocol, message format, device identity and expected traffic before building the connection. MQTT and TCP are common starting points; the implementation depends on what the hardware supports and how the receiving system works.
Decide what belongs near the device
A local gateway may collect readings from several devices, translate a protocol or store messages while the internet is unavailable. Local processing can also avoid sending data the cloud does not need.
We agree the buffer size, outage duration and behaviour when storage fills. When a connection returns, timestamps and duplicate handling help the cloud distinguish a recovered historical reading from a new event.
Give support teams something they can diagnose
Connection logs should help answer practical questions: did the device connect, was its message accepted and did the receiving system acknowledge it? We design health information and error handling alongside the data path.
For a manufacturer or integrator, the deliverable can be a device server, a gateway application or the connection between an existing device platform and your business software. Our focus is connected-product software; PLC programming and factory control engineering are outside this service.
A typical workflow
- 01Receive and validate device data
- 02Buffer data when the network is unavailable
- 03Forward and check delivery
What we would scope together
The exact work depends on your systems and the first useful release.
- ✓Protocol assessment and documented message handling
- ✓Device server, gateway or integration component
- ✓Validation, buffering, retry and duplicate handling as scoped
- ✓Connection health information and hardware-based tests
Device Connectivity & Gateway Software questions
Can you work with an undocumented protocol?
We can assess it, but unknown behaviour adds risk. Captured sample messages, access to hardware and help from the manufacturer are valuable. We would normally prove the connection before estimating the wider system.
Does MQTT guarantee that every record arrives once?
The delivery behaviour depends on the quality-of-service level and implementation. Applications still need to account for possible duplicate messages and connection recovery where relevant.
Can data be processed locally rather than sent to the cloud?
Yes, where the gateway has suitable resources. We decide what to calculate locally, what to retain and what to send based on response time, connectivity and operating requirements.

Have a device that needs to talk to another system?
Send the protocol details, a sample message and the destination. We can identify the connection work and any questions to prove first.
