New Waterproof Bluetooth Gateway

We have the new NR-01 waterproof gateway in stock.

This gateway detects Bluetooth LE advertising and sends it on to your chosen HTTP(S) or MQTT server via WiFi or Ethernet. There’s a configurable upload period and filtering by RSSI, Bluetooth Service, MAC address (including partial address) and iBeacon. It’s powered by Ethernet PoE or micro USB. It supports up to 240 advertising detections per second when using Ethernet.

We also stock a non-waterproof version.

Monitor – Presence Detection Reported via MQTT

There’s a new Linux script called Monitor that scans for the presence of beacons and other Bluetooth devices and reports to a MQTT server.

The mechanism doesn’t just scan for beacons. It combines name requests, anonymous advertisements and beacon advertisements to determine when to issue a name request to determine if a device is present and when to issue a name request to determine if a device is absent.

The author, Andrew J Freyer, provides instructions how to set up on a Raspberry Pi Zero W.

INGICS Bluetooth Gateway MQTT Service Levels

The INGICS iGS01S (WiFi) and iGS02E (Ethernet) gateways support MQTT to send data to a server.

iGS01S Bluetooth LE WiFi Gateway

MQTT defines three levels of Quality of Service (QoS) that relate to whether requests are resent if not acknowledged:

  • 0 – The broker/client will deliver the message once, with no confirmation.
  • 1 – The broker/client will deliver the message at least once, with confirmation required.
  • 2 – The broker/client will deliver the message exactly once by using a four step handshake.

The INGICS gateways only support QoS level 0. This is because these gateways have lower memory and processing capability. They don’t have enough memory to queue unacknowledged requests required of other QoS levels. The extra processing would also significantly impact the performance and hence throughput.

If you need a higher MQTT service level then try the Minew G1 that supports QoS levels 0 and 1.

Maximising Bluetooth Gateway Throughput

Our article on What are Beacons shows the kind of data sent by beacons. While this might be iBeacon or Eddystone, both are a subset of all Bluetooth advertising as sent out by all Bluetooth LE devices such as smartphones, Fitbits and even industrial machines. The Bluetooth LE advertising advertising is just a short series of numbers.

Gateways look for Bluetooth advertising and send this on to a web server together with the signal strength of the detected device, the gateway’s own Bluetooth MAC address and MAC address of the detected Bluetooth device.

Bluetooth WiFi Gateway

In some situations a very large number of devices can be detected, most of which aren’t the ones that need to be detected. This can cause either the gateway to become overloaded or too much extraneous data to be sent to the server.

All gateways have ways of filtering what advertising is sent to the server. This usually includes matching some or all of the advertising with a given hexadecimal string and the ability to ignore devices weaker than a given signal strength.

Even after filtering, it’s possible in extreme circumstances that a gateway processes too many beacons and becomes overloaded. In these cases it’s important to have a gateway that can support the highest throughput. Gateway specifications detail the typical maximum number of devices that can be detected which varies considerably between devices. Ethernet connected devices tend to be more performant than those connected by WiFi. Also consider setting the gateway to only detect beacons close by and use more gateways per given area. Consider using MQTT in preference to HTTP so as to cause the gateway to do less work.

New iGS01S Bluetooth WiFi Gateway in Stock

We have the new INGICS iGS01S Bluetooth WiFi gateway in stock.

iGS01S with USB power cable

The iGS01S is a new version of the iGS01. It’s functionally compatible with the iGS01 in that you can replace an iGS01 with an iGS01S and it will behave similarly. Hence, it’s also compatible with BeaconServer™ and BeaconRTLS™.

iGS01 gateways allow you to scan for nearby Bluetooth devices and send the scanned data up to a server, including AWS IoT, via TCP, HTTP(S) POST or MQTT.

The main change is the case which the manufacturer has changed to allow commonality of parts with the Ethernet version, the iGS01E.

We also have the matching wall holder in stock.

New Minew G1 Bluetooth Gateway Video

Minew has a new video showcasing the G1:

The G1 gateway collects advertising data from iBeacon, Eddystone, Bluetooth LE sensor and other Bluetooth LE devices and  sends it to your server by HTTP(S) or MQTT/ using WiFi or Ethernet.

Minew G1 Gateway in Stock

We have the new Minew G1 gateway in stock. The G1 gateway collects advertising data from iBeacon, Eddystone, Bluetooth LE sensor and other Bluetooth LE devices and  sends it to your server by HTTP(S) or MQTT/ using WiFi or Ethernet.

Special features of this gateway are that that it supports both WiFi and Ethernet and has a high throughput of up to 200 Bluetooth LE devices detected per second.

Bluetooth WiFi Gateways and Apache NiFi

If you are sending data from Bluetooth WiFi Gateways via MQTT then you might want to look at using Apache NiFi on the server to get data into your systems. Apache NiFi is:

“An easy to use, powerful, and reliable system to process and distribute data”

It has over 135 different processors to easily consume data and send it on to other systems.

NiFi has processors to Get and Put data to an MQTT broker. An example of re-publishing can be found at hortonworks.com.

NiFi provides a web-based user interface to manage dataflows in real time. The project was originally open-sourced by the United States National Security Agency (NSA).
