If you are rolling out many gateways, there comes a time when you start wondering if all of them are working and connected. While it’s possible to write a server side script/code to detect whether or not data has been received from the gateway in the last n seconds/minutes, this doesn’t work when there aren’t any Bluetooth devices in the vicinity of some gateways which won’t be sending payloads.
The INGICS gateways have a way of setting up a heartbeat that’s a dummy payload used to indicate a gateway is working and connected. It’s set up by telnet to the gateway and issuing the following command followed by a reboot:
> SYS HEARTBEAT 1 > REBOOT
The ‘1’ signifies every 1 minute and allows setting up to 255 minutes. A $HBRP data payload is to the server in the form:
The heartbeat functionality is available on firmware IGS01-v2.0.0 and IGS01S-v2.0.0 or later.
We have two new sensor beacons in stock. The iBS03TP is a waterproof temperature beacon with a 2m probe measuring -50C to 150C with an accuracy +- 0.5C.
The iBS02M2 measures on/off. This can be a switch or a voltage (0.5v to 50v is ‘on’).
The small PCB with a USB connector plugs into the main unit USB. The terminal block is used connect to anything that provides a switched or voltage output. This makes this beacon suitable for detecting a wide range of on/off scenarios.
The INGICS iGS01S (WiFi) and iGS02E (Ethernet) gateways support MQTT to send data to a server.
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.
The iGS04 is a new keyring/keyfob style beacon only 6mm thin. It advertises continuously and the button is used to change a value in the advertising data.
The iGS01 is similar to our other iGS beacons except it has no sensors other than the being able to detect the button press.
These Bluetooth beacons are not iBeacon nor Eddystone beacons. The advertising data is instead wholly used for sensor data. You will need an (your own) app or gateway to scan and obtain the advertising data.
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 now have the INGICS iGS02E Bluetooth to Ethernet gateway (without PoE) in stock.
This small device looks for Bluetooth LE devices and sends their advertising on to a server via TCP, HTTP(S) or MQTT including AWS IoT. If you use with sensor beacons, this provides a quick and easy way to provide for IoT sensing.
We have some early samples of the new INGICS iBS03 range of beacons in stock. They are functionally similar to the iBS01 range except are waterproof to IP67 and have a more robust case with 2m drop protection.
We stock three variants: iBS03T – Temperature sensor iBS03G – Motion (starting/moving/stopped) and fall detection iBS03RG – Accelerometer for raw xyz
There’s a type of beacon that doesn’t send out iBeacon or Eddystone advertising. Instead, it sends out standard Bluetooth 4.0 advertising containing sensor values. This means the data can be picked up via apps, gateways, Raspberry Pis or other devices that can see Bluetooth advertising.
An example of this is the INGICS iBS01 range of beacons.
The round bit in the middle is a button that can be pressed. Here’s an example for the data from the iBS01T temperature/humidity sensor:
Additionally, the ‘event’ data gives the state of the button press.
We have a new INGICS gateway, the iGS02, in stock that uses Ethernet rather than WiFi. This allows it to be used where WiFi isn’t present or where it’s considered that data needs to be sent via a more reliable wired connection. The use of Ethernet also allows for a greater throughput detection of up to 70 beacons per second (with MQTT).
The iGS02 comes with a POE adapter allowing it to be powered from the Ethernet connection for networks providing POE. Alternatively, it can be powered via the USB connection.
The MQTT/HTTP output is the same as the WiFi-based iGS01 allowing these devices to be used interchangeably.
