Cellular BLE Hub Guide

Overview

Cellular BLE Hub A100 is the bridge device between pre-integrated BLE devices and RPM IoT platform.
It’s key features are:

  • Connect BLE devices autonomously and forward measure to platform
  • Up to 5 BLE devices data are captured in parallel
  • Complete fast integration with any new BLE device without coding
  • Work in any place of LTE signal coverage. Instead ,WIFI can be considered.
  • Remote OTA

Getting Started

Step1: Power on Cellular Hub

Put cellular hub on the table and connect it to power source by USB power cable. You can watch that the red(SYS) LED light blinks slowly until being always on after a while, which means hub enters the normal work state. The green(NET) LED light becomes also on if the Internet link between hub and RPM IoT platform is established.

Pay attention:

1.  It might take long time (1~3 minutes) to activate SIM card at the first time.
2.  Hub may not work smoothly in poor LTE coverage place. Instead, wifi can be considered.

Step2: Case1,Measure Blood Pressure

Wrap arm strap and press ”START” button on BPM screen, you can watch that hub blue(BLE) light becomes on which means BLE connection is established between BPM and hub. Keep arm still until BPM retrieves BP data. Then you can watch that hub blue and green(NET) light blink in sequence, which means measure data is being transferred from device to IoT platform.

Step3: Case2,Measure SpO2/HR

Pinch your finger into the pulse oximeter, you can watch that hub blue(BLE) light is also on. Keep finger stationary to retrieves SpO2/HR data, Then you can watch that hub blue and green(NET) light blink in sequence, which means measure data is being transferred from device to IoT platform.

LED Light

Hub has three lights:

  • The RED light indicates the system status.
  • The GREEN light indicates the network connection status.
  • The BLUE light indicates the BLE connection status.

The following table summarizes the light behavior:

Light Behavior Status
red light is solid on system startup initialization completed
red light is flashing slowly system startup initialization in progress
red light is off system is not started
green light is solid on a normal MQTT connection
green light flashes twice quickly data uploaded via MQTT
green light is off a disconnected MQTT connection
blue light is solid on at least one device is connected to the hub
blue light flashes twice quickly data uploaded via Bluetooth
blue light is off no devices are connected
red/green/blue lights flashing in order an ongoing OTA (Over-the-Air) update

Web Console

WIFI hotspot Access

Hub offers WIFI hotspot for web console access. Hotspot name is ATHTECH-{mac} with password 12345678.

Web Console login

Open a web browser and navigate to 192.168.71.1. Enter the password 12345678 and click on the login button.

System State

This page shows system information like hub MAC address, active time, system time, product model, IP, MQTT status, firmware version, APN and so on. Additionally, you can try network testing by ping.

Network Setting

The default link type is LTE. You can set the APN to ‘auto’ or choose one manually.
Instead, you can also select the WIFI type, enter the correct Wi-Fi name and password.

Pay attention:

The above setting works only after you click 'Save' and restart system.

NTP Setting

System obtain correct time through NTP protocol. Basically, default NTP Setting is ok.

Platform Configuration

By default, IoT platform configuration is AWS IoT, which guarantees the MQTT session is established automatically. This configuration can be customized on demand.

Devices

The pre-integrated device’s BLE connection status can be displayed on this page. Once a device is connected to the gateway, its status will 'Connected', Otherwise ‘Disconnected’

System Restart

There are three ways to restart system:

  1. Restart system in web console.

  2. Simply press the “reset” button on the product shell.
  3. Plugging hub power cable and insert again.

Note: After modifying and saving the configuration, need to restart system to take effect.
