BLE Scanner - FAQs

BLE Scanner scans for 20 seconds and takes 10 seconds to send data over MQTT.

BLE Scanner scans in the range of 70-80 devices at a time.

BLE Scanner has a range of 40 meter line of site (considering two side, you can cover 80 meter). If you install it on a pole, it will cover area with 40 meter radius. If you install it on the wall, it will cover half the area with 40 meters radius.

Physical impediments will have impact on the RSSI value. It will also deteriorate signal. In case the physical impediment are extremely strong such as steel structure or concrete wall, the BLE Tag will not be visible.

Yes, you can configure BLE Scanner to send data to your own MQTT server. The procedure is explained in the video link : https://www.youtube.com/watch?v=vmrdqesiok8

Yes, you can configure BLE Scanner to connect to your own WiFi network. The procedure is explained in the video link : https://www.youtube.com/watch?v=vmrdqesiok8

Yes, please refer to this document to understand how to go about deploying the device in field https://easyreach.co.in/ble-asset-tracking-2/ble-scanner-understanding and-deployment

BLE Scanners scans ONLY EasyReach devices.

No, the device does not support triangulation.

If you are getting BLE Tag data from two or more BLE Scanners, you can implement logic based on the RSSI value available in the MQTT payload. A lower RSSI value means a weaker signal. Please note, the RSSI value will change in case a physical impedance is placed between BLE Tag and BLE Scanner.

MQTT, short for Message Queuing Telemetry Transport, is a lightweight, open-source messaging protocol designed for resource-constrained devices and low-bandwidth, high-latency networks. It’s a publish-subscribe protocol, meaning devices (clients) can publish messages to a broker, which then distributes those messages to other devices (subscribers) that have subscribed to the relevant topics. MQTT is widely used in IoT (Internet of Things) and M2M (machine-to-machine) applications. (Credit Google)

You can use any MQTT broker of your choice. Few links are
