1. General Introduction
This LoRa & BLE Device is designed based on BLE and LoRa technology. With the advanced LoRa technology and build-in BLE module, the LoRa & BLE Device detects the BLE beacon signal, and report to the LoRa Device. The parameters setting, such as heartbeat period, LoRa work mode is adjustable per customers’ requirements. Highlights:

The tracker can be turned on/off by long period pressing the power button for 3 seconds. When
pushing the button to power off the tracker, the red light will last for three seconds then turn off,
when push the button to power on the tracker, the red light will flash for four times then turn off.
Press the button to check whether the tracker is working, if the green "S" status light blinks, it indicates
the tracker is working. The red battery light flashes during charging and sustains when charging
completed.

4. Application Information
4.1 Function
There’re two kinds of LoRa & BLE Device, one type is indoor Device powered by external power and no battery equipped, and another type is outdoor Device powered by solar panel equipped with Lithium battery or only battery equipped. The Device supports both OTAA and ABP mode, both work in class a mode, the data rate is limited to start from DR2 to transmit big payload. DevEUI, AppEUI and AppKey, or DevAddr, NwkSKey and AppSKey are stored in the Device and are necessary for joining a network. DevEUI or DevAddr is labeled at the

back of the device. Lansitec will help to configure these parameters before shipping if necessary. After power on and join the Lora network, Device will send registration message which include the current parameters setting of the Device to Customer Server(CS). If CS doesn’t reply Device will retry for 3 times before working in default mode.
Device starts to work after receiving acceptance response or no CS reply is received after 2 registration trials. The Device reports the heart beat message to CS periodically. The duty cycle is configurable by commands from CS. Coordinate acquisition and report period depends on the BLE scan results. According to LoRaWAN specification, in Class A mode downlink response time is decided by uplink duty cycle. To avoid relying the position message for downlink configure, Device uses heartbeat message to control the downlink response time. The heartbeat period can be configured to be integral multiple of 30 seconds. The default period is 5 minutes. Heartbeat message also contains status information of the Device. It can be used by CS to monitor the Device.
4.2 Application Scenarios
The Device is managed with the following general rules:
When registration request is received from the Device,
--If CS only wants the Device to work with default parameters, CS ignores the registration
message and waits for the periodically coordinate report. Or CS should record the first-time configuration, acknowledge the request. If CS contains some history configuration of the Deviceand mismatch occurred, CS should send the new configuration to Device. Then Device updates and starts to work with these new parameters.
After registration, configuration of the Device may be changed by user. CS needs to save the
new parameters and CRC16 of the parameters. In case of receiving registration when Device reset or periodical heartbeat message, CS need to check if any configuration mismatch occurred. If necessary, CS should send the new configuration to Device in next downlink window.

Data Rate(DR0~DR15). The default value is DR2. If ADR is disabled, the Device will work in this data rate.
POS field
The Device will start BLE scanning several seconds before the end of every scan period, the default value is 3 seconds, which is configurable. Besides, scan period and send period are different, the purpose is to reduce the send delay, that’s because in some situation the outdoor Device may be configured to detect every 30 minutes or one hour, if still only send the data at the end of scan period, it will take hours to send all the beacons once there’re tens of beacons. To solve this issue, the Device will check the scan period every time, if scan period is more than 5 minutes, after it sending the data at the end of scan period, it will go on checking the buffer, if still having beacons not sent it will launch another transmission 10 seconds later till all the beacons are sent.
