Introducing BLE-enabled Remote Health Monitoring Hardware Solutions

BLE-enabled Remote Health Monitoring Solutions is built based on a three-layer architecture. Each layer serves a specific purpose in collecting, transmitting, storing, and presenting health data, ensuring a seamless flow of health data from the patient’s health monitors to the healthcare provider’s cloud platform, and finally facilitating remote care coordination by healthcare providers s well as patients’ active participation in their well-being monitoring.

First Layer: DSGW-340 BLE WiFi LTE Gateway and Health Monitors

The first lightweight portable BLE gateway is responsible for collecting health data from a range of BLE-based health monitors, including blood pressure monitors, pulse oximeters, ECG monitors, and more. And then it aggregates the data and uses Wi-Fi or LTE connectivity to securely transmit this data reliably and securely to the dedicated cloud platforms.

Second Layer - Cloud-Based Platforms by Healthcare Provider

In this layer, healthcare providers host cloud-based platforms specifically designed to receive, store, and manage patient health data. The health data transmitted from the BLE gateway is stored securely in the cloud-based platform. This data can include historical records, trends, and real-time measurements.

Third Layer - Healthcare Apps

Healthcare management console: Authorized healthcare professionals can access data from the platform, send notifications and personalized recommendations to patients.

review it, and perform data analysis to identify trends, anomalies, and potential health issues.

Patient-Facing Apps: The third layer involves healthcare apps designed for patients or end-users. These apps can be installed on smartphones, tablets, or other connected devices.

FAQs of Bluetooth Low Energy Modules

Not all BLE modules are ideally suited for developing IoT gateways, especially when they need to perform indoor positioning tasks like scanning for nearby BLE beacons. In this situation, BLE modules with strong receiving sensitivity is critical for gateway to scan for BLE devices and beacons over longer distances or in challenging indoor environments with obstacles.

The EFR32BG22 BLE SoC is an enhanced version of the EFR32BG21, offering a more powerful processor, increased flash and RAM capacity, and similar connectivity and security features.

Certainly, if you want to parse data locally without transmitting data packets directly to a cloud platform, you can achieve this by customizing the firmware running on the Bluetooth gateway. This approach allows you to add intelligence and customization to your IoT solution, and enables the real-time decision-making. Know more about our edge computing IoT gateways.

A BLE module can serve both as a main control module and a communication module, depending on how it is integrated into a specific device or application. The role it plays largely depends on the design and functionality of the device in which it is used. In many cases, a BLE module is primarily used as a communication module. Its main purpose is to establish and manage wireless communication between the device it’s integrated into (the host device) and other BLE devices, such as sensors, smartphones, tablets, or other peripherals. In some applications, a BLE module may act as the main control module for the host device. In this role, it takes on more responsibilities related to the device’s operation and functionality. Get to know our DSGW-094 BLE Cat M1 gateway with Nordic nRF52840 SoC as main control module.
