→Protocol description
Scan Response is used to send device name and manufacturer specific data. Manufacturer specific data includes Teltonika Company ID (0x089A) and protocol version (0x01). It is followed by Flag Encoded Data (Table 1) and Extended Data (Table 2). Later on, protocol will be highly configurable in and will allow to disable/enable sending of device name or any sensor value allowing to reduce size of the packet being sent.

Teltonika BTSX devices are transmitting one or two packets depending on the selected protocol. Broadcast packet + Scan response packet.
A scan response packet is sent when an active scan is used, within the BLE layer of communication.
The default for our FM devices and many other applications for example our EYE Appication or nRF connect Application is an active scan.
There are three protocols, with the following packets:
*1.iBeacon + EYE Sensors*
*2.Eddystone + EYE Sensors*
For *first* and *second* protocols only iBeacon/Eddystone packet is broadcasted and will be seen by both active and passive scans, to see the EYE Sensors packet you need to use an active scan.
In other words in an environment where no BLE devices are scanning with an active scan or in case when there are no scanning devices at all, only the iBeacon/Eddystone packet will be sent by the BTS device to conserve energy.
*3. EYE Sensors*
With third protocol, the EYE Sensor packet becomes broadcast.
In other words, in an environment where no BLE devices are scanning with an active scan or in case when there are no scanning devices at all EYE Sensors packet will be sent by the BTS device.
