Low cost BLE-GPRS-GPS-gateway

Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway? If yes then it makes sense to follow a train of thoughts listed in my IoT M2M Cookbook. Everybody can make such a gateway real for less than USD 15.

In my IoT M2M Cookbook – excerpt here:


IoT M2M Cookbook

Cover of the IoT M2M Cookbook

I explained in detail how to design a tracking device based on cellular modules (2G, 3G, 4G) and GNSS (GPS, GLONASS, Galileo).

Estimated bill of material for the low-cost BLE-GPRS-GPS-gateway in mass production:

  • GPRS, GPS, BT 4.0 (BLE) module with RTOS (Nucleus) = USD 9,50
  • MCU does not apply = USD 0
  • GSM PCB track antenna out of the IoT M2M Cookbook = USD 0
  • Bluetooth PCB track antenna out of the IoT M2M Cookbook = USD 0
  • GPS PCB track antenna out of the IoT M2M Cookbook = USD 0
  • SIM Card connector does not apply because it has a SIM on Chip = USD 0
  • USB connector + diode + low ESR capacitor < USD 1
  • Enclosure < USD 1
  • PCB smaller than 86,6 mm x 54 mm. (ISO 7810, ID-1-Format, credit card size) < USD 1
  • M2M SIM card without fee – Pay as you go SIM card
  • Summary < USD 10


Estimated one-off costs for the prototype of the low-cost BLE-GPRS-GPS-gateway:

  • GCC GNU Complier = USD 0
  • Code samples = USD 0
  • Software to develop the PCB = USD 0
  • 2 x M2M test SIM cards (standard SIM and SIM on Chip) = USD 0
  • IoT M2M Cookbook = estimated USD 100
  • Evaluation kit for GPRS module does not apply = USD 0
  • 1 x GPRS module < USD 15
  • 5 x two layer PCB by PCB Pool < USD 150 https://www.pcb-pool.com/ppde/order_productconfiguration_js.html
  • Summary < USD 300

BTW, I am working on a temperature sensor for my brother’s greenhouses. The BOM is close to the upper mentioned parts. The addition is sensors for temperature, air humidity and soil moisture on a bus system. The summary of the sensors is more expensive than the communication box.

In the end, these questions remain:

  • Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway?
  • Does it make sense to start a Kickstarter campaign?
  • Which target groups have a need for low cost such a BLE-GPRS-GPS-gateway?

Thank you in advance for a request the BLE-GPRS-GPS-module, antenna matching, antenna designs, comments or an email to harald.naumann (at) lte – modem. com

  1. Hello Harald

    I am interested in this product and would like to get a sample from you

    Low cost BLE-GPRS-GPS-gateway,

    My project involves using Bluetooth temperature and humidity sensors and transmitting the data via GPRS gateway.

    The device can be powered by electric or rechargeable batteries.

    I also require to track the asset, it will stationary most of the time, unless it goes for repairs.

    I look forward to hearing from you if you need to ask any further questions then I am available on my email

    kind regards/Shahzad

  2. Dear Shahzad,
    please be so kind and have a look in your email inbox.
    Best regards

  3. Hi Harold

    I am looking to deploy a proximity tracking kit for multiple use cases for a secure location tracking platform. Would it be possible to have a call with you and an email address from you to discuss it further. My product is Fisheye Hub. Currently on the App Store . Idea is to augment that solution with Bluetooth and RFiD trackers and ring fenced boundary readers.

  4. Rajeev, the new akorIoT SensPRO on ATMEL SAM21D or STM32L431 will be a starting point for you. The BLE module you can wire to the extension port of the SensPRO.

  5. Hi Rajeev, I will not travel this week and wait for Christmas. The new akorIoT SensPRO is a reference design on NB-IoT, LTE-M, GPRS, one our of three MCU, sensors, battery charger and a BLE module you can add on it extension port on separate PCB.

  6. Hello harald!
    I’m doing a project right now to track the location of ble beacons inside cars.
    I’m using an android device as a gateway for scanning ble, obtaining GPS location and sending the data to my server using gprs Sim card.
    However, the android smartphone based solution doesn’t seem to be working perfectly due to Android system limitations.

    So right now I’m looking for a device that can scan for ble devices, get GPS location and send it to my server and I’d be happy to use your services.

    Best regards.

  7. Hi Ro<, sorry but I can not help. Regards Harald
