We use LT-22222-L IO Controller as a reference device - the setup for other LoRaWAN devices will be similar. Step 1: Create a Device definition in TTN v3 with the OTAA keys from the example LT-22222-L IO Controller device. Three codes are required to define the device in TTN v3:
DEV EUI - Unique ID code for a particular device. APP EUI - ID code for an Application defined in TTN v3. APP Key - Unique key to secure communications with a particular device. A set of these codes are stored in each device by the manufacturer as the default codes for that particular device. Each device is shipped with a sticker with the default Device EUI as shown below. Note: You may be able to change these codes in a device by using a configuration facility on the device e.g. the LT-22222 uses a serial port access and a series of AT commands. Changing the codes may be necessary in the case where you have to use codes assigned by a LoRa WAN server. NNIONGIN LoRaWAN Gateway User Manual 21 / 48 For the TTN v3 server, you can use the codes set in the device as in the following example. Select Add Application to open the screen below. Open the Application select Add end device Start Register the end device Select OTAA activation mode The LoRaWAN version for your device should be provided by the manufacturer in a datasheet as LoRaWAN version or LoRaWAN specification.

Upgrade via Linux console 7.2 SCP the firmware to the system /var directory and then run root@OpenWrt:~# /sbin/sysupgrade n /var/Your_Image NOTE: it is important to transfer the image in the /var directory, otherwise it may exceed the available flash size. NNIONGIN LoRaWAN Gateway User Manual 42 / 48 8 FAQ 8.1 Can I make my own firmware for the gateway, Where can I find the source code?
Yes, You can make your own firmware for the NNIONGIN for branding purposes or to add customized applications. Can I use 868Mhz version for 915Mhz bands?
8.2 It is possible but the distance will be very short, you can select US915 frequency band in 868Mhz version hardware. It will work but you will see the performance is greatly decreased because the 868Mhz version has an RF filter for band 863~870Mhz, all other frequencies will have high attenuation. 9 Trouble Shooting I get kernel error when install new package, how to fix?
9.1 In some cases, when installing a package with opkg, it will generate a kernel error such as below due to a mismatch I the kernel ID:
root@nitro-16c538:~# opkg install kmod-nitro2-si3217x_3.10.49+0.2-1_ar71xx.ipk Installing kmod-nitro2-si3217x (3.10.49+0.2-1) to root Collected errors:
* satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-nitro2-si3217x:
* kernel (= 3.10.49-1-4917516478a753314254643facdf360a) *
* opkg_install_cmd: Cannot install package kmod-nitro2-si3217x. In this case, you can use the force-depends option to install such package as long as the actual kernel version is the same. Opkg install kmod-nitro2-si3217x_3.10.49+0.2-1_ar71xx.ipk force-depends NNIONGIN LoRaWAN Gateway User Manual 43 / 48 9.2 I configured NNIONGIN for WiFi access and lost its IP. What to do now?
The NNIONGIN has a fall-back IP address on its WAN port. This IP is always enabled so you can use the fall-back IP to access NNIONGIN no matter what the WiFi IP is. The fall back IP is useful for connecting and debug the unit.
(Note: fallback IP can be disabled in the WAN and DHCP page) Steps to connect via fall back IP:
1. Connect PCs Ethernet port to LG01s WAN port 2. Configure PCs Ethernet port has IP: 172.31.255.253 and Netmask: 255.255.255.252 As below photo:
3. In the PC, use IP address 172.31.255.254 to access the NNIONGIN via Web or Console. Please note the latest firmware uses port 8000 for http and 2222 for ssh access. NNIONGIN LoRaWAN Gateway User Manual 44 / 48 9.3 I connect to the NNIONGINs SSID but NNIONGIN didnt assign DHCP IP to my laptop?
This is a known bug for the firmware version before 2019-09-23 for LPS, the issue was fixed since version: LG02_LG08--build-v5.2.1569218466-20190923-1402. In the old version, user can use the fall back ip method to access and configure the device. 10 Order Info PART: NNIONGIN-XXX-YYY:
