Wireless & connectivity firmware
BLE, Wi-Fi, LoRa, cellular and mesh — chosen, built and proven in the field
Connectivity is where embedded products fail quietly: a link that works on the bench and drops in the enclosure, a radio that empties the battery, a pairing flow nobody can complete. We pick the right radio for the job, write the stack from driver to protocol, and prove range and power in the field — with the resilience habits of our defence radio work.
01 / What we build
Range, data rate, power and cost traded off on real hardware before you commit to a part.
BLE, Wi-Fi, LoRaWAN, cellular and Thread/Matter stacks integrated into your firmware and RTOS.
Self-healing device-to-device networks for sites without infrastructure.
Onboarding flows, per-device keys in a secure element, rotation and revocation.
02 / Stack
Industry-standard, boring in the good way: tools with a future, that the next engineer will know too.
Short range
Bluetooth Low Energy
Nordic, ESP32 and Silicon Labs stacks; GATT, mesh, audio
Wi-Fi
Station and AP modes, provisioning, low-power Wi-Fi 6
Thread / Zigbee / Matter
Smart-building and home meshes with Matter commissioning
NFC & UWB
Tap-to-pair and precise ranging
Long range
LoRa / LoRaWAN
Kilometre-scale, battery-powered telemetry
Cellular (LTE-M, NB-IoT, Cat-1)
Nationwide coverage with eSIM and power saving modes
Sub-GHz proprietary
Custom links where the standards do not fit
SDR & anti-jam waveforms
Frequency-hopping and resilient links from our Miltech work
Protocols & security
MQTT / CoAP
Lightweight publish-subscribe and REST for constrained devices
TLS / DTLS with hardware keys
Mutual authentication backed by a secure element
Mesh routing
Self-healing multi-hop networks between devices
Protocol buffers / CBOR
Compact, versioned payloads over slow links
03 / Approach
Link budgets calculated, then verified in the field with real antennas and enclosures.
Adaptive data rates, retries, store-and-forward and mesh so a bad day for the radio is not a bad day for the product.
Provisioning, key storage and rotation designed in — never a shared default key.
The radio is the biggest consumer; we schedule it around the battery, not the other way round.
04 / Standards
We adhere to industry standards and proven methods on every project — they are what makes the estimate hold.
05 / Infrastructure
Start
Tell us the range, the battery and the environment. A firmware engineer writes back with a recommendation, an honest scope and a price.
