1. Introduction
RA0715_R72615_RA0715Y is a ClassA type device based on the LoRaWAN open protocol of Netvox and is compatible with the LoRaWAN protocol.
RA0715_R72615_RA0715Y is unmasked for indoor inspection. RA0715_R72615_RA0715Y can be connected to a variety of sensors. A variety of
sensor combinations are required. As detectors for PM2.5, temperature and humidity, CO, NO, liquid level, and soil, 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.

Description
RA0715_R72615_RA0715Y has the power-down save network information memory function. This feature is
turned off by default, that is, it will be re-joined every time it is powered back on. It can be turned on by the
ResumeNetOnOff command. At this time, each time the power is rewritten, the last networking information will
be recorded (including saving the network address information assigned to it, etc., if users want to join a new
network, they need to perform a factory reset operation before that.), will not re-join.
Operation
1. Press and hold the binding button for 5 seconds to release (release the binding button when the LED flashes),
and the LED flashes 20 times.
2. The device automatically restarts to start re-join.

5. Data Report
The device will immediately send a version package Report and a report data with temperature and humidity and voltage
Values. The device sends data in the default configuration before any configuration is done.
ReportMaxTime: RA0715_ RA0715Y is 180s and R72615 is 900s; (subject to factory settings)
ReportMinTime: 30s;
ReportChange: 0;
Note: The device send data cycle has been programmed to be correct.
The interval between two reports must be the maximum time
RA0715_R72615_RA0715Y device does not support the ReportChange function, that is, the function is invalid.
The sent report data string is always sent according to the ReportMaxTime period
(starting to the end of the first data as a period).
The data of the device Report is: air temperature and humidity and CO2, ReportType count = 2;
Note: 1. The value of ReportMaxTime is greater than (ReportType count *ReportMinTime + 10 units: seconds);
2. Since the CO2 (MH-14) works stably, it requires about 35 seconds after power-on. Therefore, in the device model that uses
the CO2 (MH-14), the report data will be sent at about 35 seconds after power-on.
3. The device also supports Cayenne's TxPeriod cycle configuration instructions. Therefore, the device can also perform a report
according to the cycle time of the TxPeriod value; and at a certain time, the report period is ReportMaxTime or TxPeriod,
depending on which cycle time is configured last time;
4. After pressing the button, the device needs few seconds to process the sensor information, please be patient.
The data parsing reported by the device is referenced by the Netvox LoraWAN Application Command document and

7. Important Maintenance Instruction
Your device is a product of 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 moisture 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 can damage its detachable parts and electronic
components.
• Do not store in excessive heat. 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. Rough handling of equipment can destroy internal
circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not apply with paint. Smudges can block debris in detachable parts and affect normal
operation.
• Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries
may also explode.
All of the above suggestions apply equally to your device, battery and accessories. If any device is
not working properly.
Please take it to the nearest authorized service facility for repair.
