  1. Dear Harald Naumann,

    I am looking for Beacon that broadcast only in One Direction or low range such as 2-3 inches. Could you please advice if can be possible and so can I buy few for testing first? Preferbly with eddystone support. FYI, If all well, we may need at least 1000 pcs

  2. Hi Gupta, you will find an offer in your email inbox. 2 to 3 inches is no problem. The beacons support several protocols and Eddystone is supported as well.

  3. Hi Harald

    Looking for Beacons which support both ibeacon and Eddystone platforms. We are working on a project where we need the reach of bluetooth signals to be maximum. Can you please provide a quote for 1000 pieces and if possible a test kit will do for us to do intial setup. Looking forward for your email.

  4. Dear Sivaganesh,
    You will find an offer in your inbox.
    Best regards

  5. Dear Harald,
    I building an asset tracking solution for laptops and mobile devices. What kind of Bluetooth Antenna do I need to procure for an 8X8 meter area?

    Also, please provide quote for 300 beacons and wall-mount assembly.


  6. Hi Rafeeq,
    Please find another close the same messages or questions on BLE indoor localisation to me as below. I get the question again and again at least once a month. It is time for a block post on this topic.

    What is the recommended way to implement BLE beacons to perform indoor localisation?
    What is the preferred algorithm for iBeacons to perform user localisation? Fingerprint based? Triangulation based?
    How can you triangulate a phone’s exact location in a restaurant with only a few beacons?
    I would like to talk to you about BLE tracking. I have been working on a project for a while and running into walls
    We are a team of 5 people who are interested in the concept of proximity messaging and we are interested in developing a Mobile App in IOS and Android so that Consumers can benefit from the offers which retailers will be offering them by proximity messaging while they are in their stores
    We are working on a project where location Accuracy is critical for our product. I have looked through your articles on Low Energy BT for triangulation. Specifically, we are having problems in Urban Canyon environments. Do you have any articles/ideas that will provide the high level of location accuracy in these environments? Please send me any relevant info.

    Triangulation on BLE is impossible because on 2400 MHz you will have a lot of reflections, multipath plus phase shift. If you would like to make a study, then just order a kit with 5 BLE beacons for estimated Euro 50 including free of charge app for iOS and Android. After that, you place the 5 beacon or even more in a room with no people inside. Put your smartphone on a trolley and move it around. The measured field strength you write in an Excel table. After that, you make the same test with 5 beacons and 5 people and put the BLE beacon in their pockets. Let the people turn in steps of 15 degrees and measure it the field strength again. The human body is mainly water and the resonance frequency of water is in the near of 2400 MHz. Remember that your microwave oven is operating in the 2400 MHz frequency range for that reason.
    The third test could be to measure the field strength of 5 beacons in front of you at 5 different places. Just walk in steps of one-meter closer to the beacons and write the measured field strength in a table. The result will be that the field strength will maybe decrease even when you are moving closer to the beacon. The reason is multipath and phase shift. Another result will be that the field strength will not increase linearly. This is based on multipath phase shift as well.

    Fingerprinting will need a reference. However fingerprinting is not immune against multipath and phase shift as well. If you change the smartphone, the place in your pocket change then the signal loss with change as well. Fingerprinting will help to get a better result, but not accurate enough to generate a position on meter level. The fingerprinting will run better if you place BLE beacons in the room and measure the field strength with another beacon. A beacon to beacon communication will help with more accurate data than a beacon to smartphone communication. There are some further algorithms that you can use for optimising the calculation of the position, but this you can’t do by using smartphones on BLE only.

    A detection on room level is possible. If you add Kalman filters and some more sources like the magnetic field of the earth, accelerometers or even ultrasonic sound then the result will be much better than on BLE beacons only.

    A package of 3 beacons will costs Euro 50 only. Just order it, make a test and make a decsion.


  7. Hello, could you share the Wall mounted bracket 3d print file? Thank you.

  8. Hi Thiango, the property rights for the wall mounted bracket are with a third party. Sorry, there is no change.

  9. I want to know how it is made and do you offer application development along with product manufacturing. Our idea is like having bluetooth finder as well apps integrated to it like conpany tiles and trackr. How much will it cost per piece for manufacturing and how small can you make plus do you offer complete apps development?

  10. You can order in single pieces.The smallest set contains five pieces. You have the freedom to order the dev kit and to change the firmware. App development will be your part or a part of local developers.

  11. I wanted to launch a BLE product like tiles and trackr company. Can you guys manufacture us product like them but smaller if possible. As well as do you offer apps development.Looking to buy in bulk.

  12. We can do anything. Do you have a budget for development?

  13. Hello Harald, we are looking for bluetooth trackers that can also have GPS functions enabled / disabled.

    Please advise smallest size available
    If need be, to eliminate GPS function, can the blue tooth tracker size be reduced?

    Looking for small bluetooth tracker, in other words.

  14. Hi Harald,
    could you please asend me a quote for eval kit, payment and shipping options.How soon can i get it (im in München)

  24. Would love a quote for your trackers!

  25. Hi Harald,

    I am looking to deploy beacon to transmit a brief (less than 100 character message to cell phone) that can be simply activated for security warnings and notifications. Maybe by push button? Do these devices broadcast continually while powered on or are there other options? Many thanks.

  26. Hi Brian, they broadcast and 100 charaters are maybe to long for a BLE beacon.

  27. Hi Robert, it is a a BLE beacon ad not a tracker.

  28. Hi Gustav, just drop me an email to harald.naumann (at)

  29. Hi Harald,,
    Im working in iOS and android app that use géolocalisation indoor to find out devices (iPad , iPhone..) , so then i need to w work with beacon ,Eddystone ,BLE , sir what should i use to get my purpose . i have to detect location each device using a map 2D .
    Many thanks.

  30. Hi Yougina, the answer is written here:
    Is it possible to use iBeacons / BLE beacons for triangulation or BLE indoor localisation?

  31. Hello Harald, Just a few questions. Kindly reply my email.
    I am not much of a Tech person but I know what i expect from a beacon.

    1. Do your beacons support eddystone and ibeacon push notifications at the same time?
    2. Are they secure?
    3. are the SDK’s robust enough to provide proximity and user analytics?
    4. Can a user broadcast urls, images?
    5. I intend to purchase between 100-500 units can I get a sample to use as test device? thanks

  32. Howie, I answered to you by email.

  33. I have stores in OKC, usa, I sell cbd products. I want to use these to advertise my business. Can I program them with different ads once they are placed at different locations from my laptop? OKC is about 50 miles wide. I don’t want to have to go to each location and get the device and program it. Wes Williams 405 520-3410 cst. Oklahoma

  34. Hi Harald,

    I am doing some research on a bluetooth proximity device and need some guidance.

    I am looking for a beacon that can be attached to a power source like a car battery and once the connected device (phone, wristband etc.) gets far enough away it loses connection and cuts power to the battery. Is this possible? What parts would I need and cost. Thank you in advance.

    Devin Creasey

  35. Hi Devin, yes this is possible.
