Challenge
Only live readings sync; offline history is lost
Agnotic approach
We implement the device's stored-record transfer (e.g. glucose RACP) so history isn't dropped between syncs.
Bluetooth / BLE
Bluetooth / BLE Medical Device Integration
We build native Bluetooth Low Energy connectivity for medical devices — GATT profiles, secure pairing, and reliable data sync — and map the readings into a consented, FHIR-ready clinical record. Real firmware-to-cloud engineering, not just an SDK wrapper.

What BLE medical-device integration involves
Bluetooth Low Energy medical devices expose data through the GATT (Generic Attribute Profile) — a hierarchy of services and characteristics. Many device categories map to standardized Bluetooth SIG health profiles: the Blood Pressure Service, Glucose Service, Health Thermometer, Pulse Oximeter, Heart Rate, and Weight Scale services, each with defined characteristics and data formats. Others expose proprietary GATT services that must be reverse-engineered from a spec. On top of that sit pairing, bonding, and encryption, plus platform quirks in Core Bluetooth (iOS) and Android BLE.
The hard part is reliability at the edge: handling connection drops and background reconnection, syncing the device's stored offline history (not just live notifications), de-duplicating records across syncs, and doing it within iOS and Android background-execution limits. Then the readings must be normalized and mapped into FHIR Observations with consent. We build that firmware-aware, mobile-native pipeline so device data arrives complete and correctly typed.

Common failure modes
BLE integration pitfalls — and how we handle them
Challenge
Connections drop in the background
Agnotic approach
State-restoration and reconnection logic within iOS and Android background-execution limits.
Challenge
Pairing/bonding differs per device
Agnotic approach
Per-device pairing flows — just-works vs. passkey — validated against real hardware early.
Challenge
Proprietary GATT payloads are opaque
Agnotic approach
We decode the vendor's characteristic spec and build a tested parser rather than guessing.

Our Process
How we deliver BLE integration
A phased approach treating GATT profiling, pairing, and background sync as parallel tracks.
1.
Discovery & Scope
We profile the device's GATT services — standard or proprietary — and design the pairing and sync model.

2.
Prototype & Pairing
We validate pairing, bonding, and characteristic reads against real hardware early.

Profile table
Standard Bluetooth SIG health services
Many device categories map to a standardized GATT service — which speeds integration.
| Service | Device category | Data | Notes |
|---|---|---|---|
| Blood Pressure Service | BP monitors | Systolic/diastolic/pulse | Standardized; includes measurement status flags. |
| Glucose Service | Glucometers | Glucose + context | Offline record access via RACP. |
| Pulse Oximeter Service | SpO2 devices | SpO2 + pulse | Spot-check and continuous variants. |
| Weight Scale Service | Scales | Weight + BMI | Multi-user support in spec. |
| Proprietary GATT | Vendor-specific | Varies | Requires vendor protocol spec; more effort. |
Standard services integrate faster; proprietary GATT needs the vendor's characteristic spec, which we handle.

Frequently Asked Questions
A BLE integration — GATT profiling, pairing, offline sync, and FHIR mapping — typically runs 6–10 weeks. Devices using standard Bluetooth SIG health services are faster; proprietary GATT protocols and strict background-reliability requirements add time we scope upfront.
