1.Introduction
RA0715_R72615_RA0715Y is a Class A device based on the LoRaWANTM protocol of Netvox and is compatible with the
LoRaWAN protocol.
RA0715_R72615_RA0715Y can be connected with the sensor of the temperature and humidity, and CO2. The values collected by
the sensor are reported to the corresponding gateway.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other
communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance.
Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption,
transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.

Turn on the device to search the network.
The green indicator keeps on for 5 seconds: success.
The green indicator remains off: fail
Had joined the network
(Not in the original setting)
Turn on the device to search the previous network.
The green indicator keeps on for 5 seconds: success.
The green indicator remains off: fail.

Description
RA0715_R72615_RA0715Y has the function of the power-down saving the memory
of network-joining information. This function acquiesces in turn off, that is, it will
rejoin every time when it is power on. If the device is turned on by the
ResumeNetOnOff command, the last network-joining information will be recorded
when every time it is power on. (including saving the network address information
that it is assigned, etc.) If users want to join a new network, the device needs to
perform the original setting, and it will not rejoin the last network.
Operation Method
1. Press and hold the binding button for 5 seconds and then release
(release the binding button when the LED flashes), and the LED flashes 20 times.
2. The device automatically restarts to rejoin the network.

5. Data Report
After power on, the device will immediately send a version packet report and two data reports including CO2, temperature,
humidity and voltage.
The device sends data according to the default configuration before any other configuring.
ReportMaxTime :
RA0715 and RA0715Y is 900s,
R72615 is 1800s (subject to original setting)
* MaxTime cannot be set less than 15 min
* The value of the ReportMaxTime should be greater than ReportType count *ReportMinTime+10
ReportMinTime :
30s (US915, AU915, KR920, AS923, IN865)
120s (EU868)
ReportType count : 2
Note:
(1) The cycle of the device sending the data report is according to the default.
(2) The interval between two reports must be the MaxTime.
(3) ReportChange is not supported by RA0715_R72615_RA0715Y (Invalid configuration).
The data report is sentaccording to ReportMaxTime as a cycle (the first data report is the start to the end of a cycle).
(4) Data pocket: CO2, temperature, and humidity.
(5) The CO2sensor operates stably. It takes about 180 seconds after power-on to send the data report.
(6) The device also supports the TxPeriod cycle configuration instructions of Cayenne. Therefore, the device can
perform the report according to the TxPeriod cycle. The particular report cycle is ReportMaxTime or TxPeriod
depending on which report cycle was configured last time.
(7) It would take 180 seconds for the sensor to sample and process the collected value after pressing the button,
please be patient.
The device reported data parsing please refer to Netvox LoraWAN Application Command document and Netvox Lora
Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index

7. Important Maintenance Instruction
The device is a product with superior design and craftsmanship and should be used with care.
The following suggestions will help you use the warranty service effectively.
• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic
circuits. In case the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and
deform or melt some plastic parts.
• Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form
inside which will destroy the board.
• Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate
structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repairing.
