IoT product engineering since 2017

We bring the building blocks and the engineering.You build your business.

Because your project builds on radio hardware, a platform and modules we designed and control, it skips the riskiest work: getting the radio right, getting through certification, and running the cloud. And one partner stays accountable for all of it, instead of three suppliers and an integrator to keep them aligned.

IoT building blocks

Our IoT building blocks

Most of the risk in a connected product sits in the radio, the certification and the cloud. We removed that risk once, in hardware and software we control, and we reuse it on every project.

01 Cellular IoT module

Walter

An ESP32-S3 and a Sequans GM02SP modem on one board of 55 by 24.8 mm, with LTE-M, NB-IoT, WiFi, BLE and GNSS. Certified in five regions and drawing 9.8 microamps in deep sleep.
- LTE-M, NB-IoT, WiFi, BLE, GNSS
- 9.8 uA deep sleep with PSM
- CE, FCC, IC, RCM, UKCA

02 Broader coverage, same footprint

Walter Cat 1 bis

The same module, the same software, a Cat 1 bis modem. For products that need wider coverage, higher throughput and global roaming rather than the lowest possible power.
- Cat 1 bis, WiFi, BLE
- GNSS hardware ready
- Drop-in replacement for Walter

03 IoT platform

BlueCherry.io

A fully encrypted IoT platform that keeps no private device data in the cloud. Smart devices, not a smart cloud, which is why there is no lock-in and why response times feel local.
- No private data stored in the cloud
- Direct device connections, local response times
- FOTA updates and white-label app

04 Linux system-on-module

DPT-Module

A 27.5 by 52 mm OpenWrt Linux module with a factory-calibrated WiFi radio. The workhorse behind the products that need a real operating system on the device.
- Qualcomm Atheros AR9331
- 64 MiB RAM, 16 MiB flash
- CE and FCC certified

Services

How we can help

Take BlueCherry.io on its own and connect the devices you already build. Hand us a complete product to design, certify and put into production. Or anything between the two. We start from where your project already is.

01 Connectivity as a service

BlueCherry.io platform

Put your devices on an encrypted IoT platform that keeps no private data in the cloud, with a management portal in your own brand and firmware updates over the air.

Secure remote access
White-label BlueApp
Firmware over the air
Alarms that reach a person

Customer references

Products in the field, in industries that do not forgive downtime

Lifts, refrigeration, wellness installations, fishing vessels, livestock, lighting and vehicle diagnostics. Devices that have to work when nobody is watching them.

Customer projects

Selected work

Two projects that show the range. A controller for a wellness installation assembled from twenty suppliers, and a data concentrator that has to survive the North Sea.

SwimControl and Mecodo Wellness installations, Belgium

One controller for a wellness installation built from twenty suppliers

A wellness installation is a swimming pool, often with fountains and jet pumps, plus a hot tub, a steam room, a sauna and a solarium. Every heater, valve, pump and sensor in it comes from a different manufacturer with its own specification. SwimControl, a Belgian specialist in bespoke installations, wanted to stop compromising on components in order to keep the control system manageable.

Omni-C, De Boer Marine and ILVO Maritime and marine research, Belgium and Netherlands

Every system on the bridge, reporting from the North Sea

Ships operate in harsh conditions, far from help, and every engine, bridge instrument and piece of nautical electronics has to keep working. The Belgian and Dutch partnership of Omni-C and De Boer Marine needed a single device that everything on board could connect to, so installations could be managed, maintained and repaired remotely and in time.

The firm

A partner you can hand a product to for the next ten years

DPTechnics has been designing connected devices since 2017. Our engineers do their own radio layout and their own pre-compliance measurements, from the head office on the Belgian coast and a second office in the United States. Every project ships with its schematics and its source code, so the product stays yours. That matters when the device you sell today still has to be serviceable in ten years.
