Using KotahiNet’s Network

A good antenna is important. For short distances, a simple wire or coiled wire will do. However, to connect over a distance to KotahiNet’s public LoRaWAN network, a proper monopole antenna, such as a rubber duck antenna, is required. NEVER try to connect without an antenna- it can lead to the board being permanently damaged.


Building Nodes/Devices to Connect to KotahiNet

There are two basic options- either run the LoRaWAN (network code) stack on the MCU or on a separate LoRa module. Increasingly, people are preferring the former for new IoT products but both options are available. At the hardware level, most solutions are based on a Semtech’s SX1276 LoRa transceiver.



The advantage of this option is using a single MCU to run both the LoRaWAN stack and custom application firmware.

For LoRaWAN dedicated devices in commercial production, a System in Package (SIP) is recommended. The three options are AcSIP’s S76SMurata’s CMWX1ZZABZ, and Microchip’s SAM R34/R35. All of these have both the MCU and Semtech’s LoRa chip within a single module, typically just 1 cm x 1 cm. Their respective development boards EK-S76SXBB-L072Z-LRWAN1, and SAM R34 Xplained Pro Evaluation Kit provide a pathway from prototyping to full commercial design. The Microchip SIP comes with its own LoRaWAN stack while AcSIP and Murata allow any LoRaWAN stack to be used.

The Tuino 1 LR1 is both Arduino compatible as well as uses the Murata SIP module. It’s therefore a good combination of Arduino prototyping ease with an upgrade path to commercial products.

For prototyping and beginners, an Arduino forms a good base. Adding a LoRa shield is all that’s required. Examples include those from Dragino, GlobalSat,  Cooking Hacks, IMST, and RAK.

Alternatively, an Arduino compatible board with a LoRa module provides a simple prototyping platform. Examples include Adafruit Feather M0SODAQ ONE, Libelium WaspmoteSeeeduino,  Ethicstech, Marvin, Badgerboard, and Rocket Scream.

STM32 Nucleo pack for LoRa and certified embedded software solution (I-CUBE-LRWAN) provides the means to set up a complete Class A LoRaWAN node.


LoRaWAN on LoRa module

This option requires two MCUs but allows using simple AT type commands to communicate with the LoRa modem. By using an external LoRa modem, this is a good choice when the device or application needs to be independent of wireless communication or allow different wireless communication technologies to be easily swapped or added.

Since the LoRaWAN code is embedded within the LoRa module and usually cannot be changed, it is important to confirm that the particular manufacturer’s firmware allows it to be used with KotahiNet’s network, i.e. used with KotahiNet’s band plan or the Indian 865 one. Otherwise, if it is an EU 868 module, confirm the channels can be configured to KotahiNet’s band plan using AT type commands.

Note that modules based on the SX1276 chip are a better choice than those based on the SX1272. Also, some modules only support Class A, so if a Class C device is required, that needs to be checked.

Microchip’s RN2483 is a popular choice (configuration instructions) as it has been available the longest.

Other options include  Gemtek, GlobalSat, HopeRF, IMST, MultiTech xDotNiceRF, RAK, RisingHFAnylinkDapu, Embit, inAir9B, Turbo, and Kiwitec (a Chinese company).



Multi-protocol Options

While still early days, manufacturers are beginning to offer options that combine LoRaWAN with BLE (Bluetooth Low Energy). This provides a low power option for both short and long distance wireless connectivity. Another advantage is being able to connect to the device from a smartphone, for example to configure it using an app.

One option is the LoPy. Others are Telit RE866 and Laird RM1XX.

AMIHO combines wireless M-Bus with LoRaWAN.

New options to combine LoRaWAN with Sigfox and/or NB-IOT / LTE Cat M-1 to provide multi-network capabilities are also becoming available.
