Page 3: Installation
Flex2 transmitters are also shipped without the provisioning and the receiving system. For these versions, the user must manually configure the LoRaWAN radio parameters into the measurement module via USB. With this functionality, the effortless interchangeability of the measurement modules is lost. - Page 4 2. Connect a micro-USB cable to the connector in the measurement module, and the other end of the cable to a computer. 3. Launch the Mekuwin program (available for free at www.nokeval.com). 4. In Mekuwin, choose the correct port. If the port is not visible, try to reconnect the cable to the computer 5.
- Page 5 • Unconfirmed (default): The device will transmit each packet once not expecting any acknowledgement. If the packet is lost due to a collision with another transmission or any disturbance, it is lost. • Confirmed: After transmitting a packet, the device will listen for an acknowledgement from a receiver and retransmit up to two times if not getting acknowledged.

Flex2-Radio modules LoRaWAN has a regional specification, called Regional Parameters (available free at www.lora- alliance.org), that describes channel plans for different regulatory regions around the world. The radio module should be chosen according to these channel plans. Before using the radio module, make sure it is legal in your country. Credentials All the provisioned radio modules use OTAA activation mode. -
Page 9: Uplink Payload Structure
The following tables and examples describe how the data can be extracted from the uplink payload. This information is only needed when the Flex2 device is integrated into a system that is not provided by Nokeval. Protocol for EU868 radio module The payload data format consists of a protocol version field and 1 or more messages in length-type- data format. - Page 10 After the measurement flags, the measurement data is provided. Sometimes a conversion may be needed in order to get the reading right. All the needed conversions and the units they provide are described in the table below. After the measurement data, the message has a status bit flags field describing which status fields are included, similarly to the measurement bit flags.
- Page 11 Type 12: Debug information Debug information message. This should be skipped when reading the messages. Example uplinks Here are some example uplinks to help clarify how the uplink payloads are structured. Bytes are presented as hex values, numbers are LSBF. E.g., consecutive bytes 0x01 and 0x23 converted to uint16 equals 0x01 + 0x23*0x100.
- Page 12 Protocol for US915 radio module The payload data format consists of different types of messages. Each packet can hold one or several messages. Packets that hold only 1 message are in type-data format. Type 100 defines that the packet holds several messages that are in length-type-data format. Example payloads are presented at the end of this chapter for reference.

Page 14: Maintenance
Normally the recalibration includes replacing the battery. The calibration certificate for the measurement module can be downloaded from www.nokeval.com. The nSens module is an exception. As the calibration data is stored in the nSens probe, it is sufficient to recalibrate the probe only. -
