Low cost BLE-GPRS-GPS-gateway

Bluetooth-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: http://www.gsm-modem.de/M2M/m2m_iot_cookbook I explained […]
