Use your GL.iNet devices for WiFi detection

GL-iNetGL.iNet is a leading manufacturer for WiFi routers with openWRT pre-installed. This means that out of the box GL.iNet routers run openWRT. The BlueMark Zero firmware is supported by these devices. It means that with a few steps you can turn your GL.iNet device(*) into a device that detect WiFi devices. BlueMark Zero supports the full range of GL.iNet routers.


(*) The GL-MT300N-V2 device is not supported (directly) as it is shipped with a binary WiFi driver that does not provide monitor mode; needed for detection of devices. It can be solved by installing/upgrading the OEM firmware by one of the LEDE project.

Install BlueMark Zero

Installing BlueMark Zero is easy.

  • Setup your GL.iNet device (set up password, timezone)
  • Login to the GL.iNet device by SSH (e.g. ssh root@
  • Retrieve the installation scrip and execute itt, enter this commands.
    • cd /tmp; wget
    • sh install.sh
  • The installation script will ask two questions, enter a sensor ID and a software license. The sensorID is a number to identify the sensor. For instance if you enter 100, all collected data will be assigned to sensor with sensorID 100. It is wise to choose sensor IDs unique. So you won’t have project with the same sensor IDs. The other questions is to enter a software license. This license is needed to unlock the firmware.  Once installed the firmware will check roughly every 4 hours if the license is valid and if successful will unlock the firmware. Licenses can be generated at our license portal.
  • After (automatic) rebooting your GL.iNet router will start sensing!
  • Check the BlueMark detection settings at (The regular URL does not work due to the GL.iNet firmware.)
  • The BlueMark firmware supports different ways of outputting data. The firmware can act as TCP server and output the data as JSON or XML objects. The default output mode is to write the detected devices to SQL text strings. Periodically those files are compressed and sent to the server via SCP communication. To set this mode up, a SSH key has to be generated at the sensor. Its public key is needed at the server to authorise uploads
    • By default the sensor has a demo SSH key installed, it allows to upload data to our demo server.
    • At the sensor perform this command to generate a unique key: dropbearkey -t rsa -i /root/.ssh/id_rsa 
    • Use the public key at the server to allow the sensor to upload data. It is advised to use one key per project for security reasons.

Bluetooth detection; Classic, Low Energy and iBeacon support

bluetooth_low_energyIn the latest firmware BlueMark Innovations have launched support for Bluetooth detection. All BlueMark sensors including BlueMark zero support this new feature by upgrading the firmware and adding a Bluetooth USB dongle. Bluetooth detection is a great add-on to WiFi analytics or can run stand-alone.

Bluetooth Classic detection is important for (motorized) traffic applications. Although popular smartphones like Android and iOS can’t be detected, most car kits or GPS navigation can be sensed. Bluetooth Classic is an active sensing method, meaning that the sensor will transmit packets to ask for nearby Bluetooth devices. As WiFi uses the same frequency, there may be some performance degradation in WiFi sensing.

Bluetooth Low Energy (BLE) is used mostly to set up a wireless connection between smartphone and accessory like wireless earphones, smartwatch. Detection of BLE devices is different compared to Bluetooth Classic and is completely passive. Passive means that the detection only listens for incoming BLE packets similar to WiFi sensing. Most BLE devices transmit every second or more a packet. Besides smartphone accessories, also newer car kits have BLE support and can be detected.

The final application is the detection of Apple iBeacons (and Google Eddystone beacons). An iBeacon is a special kind of BLE device. Although iBeacons are mostly fixed installations e.g. for instance in a shop, it allows asset tracking. Currently there are a lot of cost-effective battery powered iBeacons available in different form factor such as tags, credit cards. Provide your visitors iBeacons or attach them to your assets to allow tracking.

BlueMark zero: use your own hardware

bluemark zeroBlueMark Innovations introduces the BlueMark zero; a software license to run BlueMark firmware on your own hardware.

In some applications, you just want to use your own hardware instead of a regular BlueMark sensor. For these applications the BlueMark zero is introduced. The BlueMark zero is  basically firmware that runs on most openWRT devices. We provide an install script to install the software. During the installation you also need to provide a serial number/license. Once installed the firmware will check roughly every 4 hours if the license is valid and if successful will unlock the firmware.

Licenses can be generated by customers at our license portal. In this portal you can choose subscription of 1 month, 1 year or 3 years.

At this moment the following platforms are supported:

  • Atheros AR71xx
  • Mediatek MT7620
  • Ralink RT305x
  • Broadcom brcm63xx
  • MikroTik RB951Ui-2HnD router
  • Raspberry Pi

New flagship sensor launched during TT festival

TT festivalDuring the TT festival June 22 to 26th in Assen the new flagship BlueMark bm2000 sensor has been launched. The TT festival is a multi day music event in the inner city of Assen organized parallel with the TT GP motorcycle races. Last year 150 000 people visited the event. The new sensor has improvements over the BlueMark 1000 sensors, such as lower power consumption which is ideal for battery-powered operation. Also the new flagship sensor has a power sensor the measure the current power consumption and battery level.  Moreover, the on-board I2C interface allows to add other types of  sensors such as sound, temperature etc. which is ideal for smart city applications.

During the festival 40x BlueMark bm2000 have been deployed to measure crowd movements in the inner city of Assen. The ICT institute CTIT of University of Twente will analyze the data. In total more than 75 million raw data points have been collected during this period.


Innofest – Follow the crowdinnofest

Also during the event a meeting was organized between crowd professionals by Innofest. BlueMark was one of the key note speakers and gave a presentation about the results of last year. Also an interview was given to RTV Drenthe which can be found here:

Serious Request 2014 Haarlem

BlueMark has analyzed the visitor flows during Serious Request 2014 in Haarlem, the Netherlands. Also this edition showed an increasing number of visitors attending this major event in the Netherlands.

Serious Request is a family of annual multi-day, multimedia fundraising event for International Red Cross initiatives. During the Dutch 3FM Serious Request, three popular radio DJs are locked up for six days in a small temporary radio studio (the “Glass House”), placed in a main square in a different city each year. Living on a juice-only fast, the DJs make an interactive, themed broadcast around the clock, while regular programming on the station is suspended. Instead 3FM and its website are completely dedicated to the event, which is also transmitted as a continuous audio and video live-stream. Additionally there is television coverage, integration with social media, and a dedicated mobile app.

Passanten 24/7

Locatus en BlueMark gaan samenwerken op het gebied van continu winkelpassanten tellen. Passanten 24/7 staat voor een nieuw tijdperk van passanten tellen; 24 uur per dag, 7 dagen per week, automatisch winkelpassanten registreren via wifi in combinatie met brickstream. Zonder de privacy van passanten aan te tasten.


Met Passanten 24/7 kun je snel schakelen. Door passanten continu te registreren kunnenPassanten-winkels Locatus retailers, gemeenten en vastgoedeigenaren een goed druktebeeld krijgen van hun (winkel)omgeving. Dankzij de samenwerking tussen Locatus en BlueMark kan een optimaal informatieplatform geboden worden.


Niet alleen cijfers per maand of week, maar ook per uur. De informatie wordt ontsloten via een dashboard met overzichtelijke grafieken en tabellen. Bovendien kunnen de passantenstromen ook letterlijk in kaart gebracht worden op de GOAD Plans van Locatus.


Deze realtime passanteninformatie is ideaal voor het monitoren van retaillocaties, en geeft antwoord op vragen als:

  • Welke delen van het centrum zijn populair/minder populair, en hoe verandert dit?
  • Wat is de invloed van evenementen?
  • Hoe ziet het druktebeeld in de loop van een week eruit?
  • Hoeveel bezoekers trekt de koopavond of de koopzondag?
  • Hoe presteert mijn winkel als ik dat vergelijk met passanten die voorbij komen?


Optimale betrouwbaarheid
Sinds juni 2012 test Locatus het continu tellen. Na twee jaar onderzoek staan wij garant voor de gekozen meetapparatuur en de gebruikte methodiek: 24/7 passanten meten via wifi-sensoren van BlueMark. Deze metingen worden bovendien met regelmaat geijkt met brickstream camera’s (tellen alleen kruinen van voorbijgangers) en handmatige tellingen.


Privacy gewaarborgd
Locatus & BlueMark nemen privacy serieus. We doen geen enkele poging om de data of het winkelgedrag aan specifieke personen te linken. Direct na registratie van het wifi-signaal wordt het MAC-adres verwijderd. De informatie die wij aanbieden is conform richtlijnen van het College Bescherming Persoonsgegevens.
