Setting up a private LoRaWAN network with WisGate Connect gateway

RAKwireless Wisgate Connect Gateway Review with Link.ONE devit

In this guide, we’ll explain how to set up a private LoRaWAN network using the Raspberry Pi CM4-based RAKwireless’ WisGate Connect gateway and Docker or Portainer to install NodeRED, InfluxDB, Grafana, and other packages required to configure our gateway. The WisGate Connect is quite a versatile gateway with Gigabit and 2.5Gbps Ethernet plus several optional wireless connectivity options such as LoRaWAN, 4G LTE, 5G, WiFi 6, Zigbee, WiFi HaLoW, and more that can be added through Mini PCIe or M.2 sockets, expansion through WisBlock IO connectors and a 40-pin Raspberry Pi HAT connector. We’ll start by looking at the gateway features in detail, but if you already know all that, you can jump to the private LoRaWAN network configuration section. WisGate Connect unboxing, specifications, and teardown RAKwireless sent us a model with a Raspberry Pi CM4 equipped with 4 GB of RAM and 32 GB of eMMC memory, GPS and […]

Getting Started with LoRaWAN on SenseCAP K1100 sensor prototype kit (Part 1)

CNXSoft: This getting started guide/review of the SenseCAP K1100 sensor prototype kit is a translation of the original post on CNX Software Thai. The first part of this tutorial describes the kit and shows how to program it with Arduino to get sensor data to a LoRAWAN gateway and display it on Wio Terminal, before processing the data in a private LoRaWAN network using open-source tools such as Grafana. The second part – to be published later – will demonstrate the AI capability of the kit. In the digital era where IoT and big data are more prevalent, a large amount of data is required to be collected through sensors. To enable the digital transformation, SeeedStudio’s SenseCAP K1100 comes with all necessary sensors and equipment including the Wio Terminal, AI Vision Sensor, and a LoRaWAN module. With this plug-and-play platform, makers can easily create DIY sensors for data collection and […]

Linux Capable Smarphones Database Launched with over 200 Models

Recently there have been companies working on smartphones that ship with Linux with Purism Librem 5 and Pine64 PinePhone being the most popular. But it has been possible to install Linux on various other (Android) phones thanks to projects like PostMarketOS or UBports’ Ubuntu Touch. But to make it easier to find out whether your phone is supported, the guy(s) at Tuxphones have created a database of phones that can run Linux. There are currently over 200 devices listed. The database is not updated manually, and scripts are used to scrape websites and wikis of open source projects such as PostMarketOS, UBports, Asteroid OS, or Maemo Leste. Some Linux operating systems such as Tizen or Sailfish OS are not included because they are not fully open-source nor independent. The use of scripts means the database does not only contain phones, but all some SBC’s, smartwatches, and TV boxes. If you […]

GearBest Database Was Left Unsecured For 2 Weeks

GearBest is one of the most popular Chinese online stores, and we often feature products sold by the company on the website. However, VPNMentor research team headed by Noam Rotem, a hat hacker and activist, discovered a serious security breach in Gearbest, where their database was completely unsecured for a period of time. Specifically the research team was able to access the following databases in March 2019: Orders database with products purchased, shipping address and postcode, customer name, email address, phone number Payments and invoices database with order number, payment type, payment information, email address, name, IP address Members database with name, address, date of birth, phone number, (unencrypted) email address, IP address, national ID and passport information, (unencrypted) account password They discovered 1.5+ million records in total. They managed to login successfully to two accounts from the database breach for testing. Payment information included data related Boleta (used in […]

How to Write ESP8266 Firmware from Scratch (using ESP Bare Metal SDK and C Language)

CNXSoft: This is a guest post by Alexander Alashkin, software engineer in Cesanta, working on Mongoose Embedded Web Server. Espressif’s ESP8266 had quite an evolution. Some may even call it controversial. It all started with ESP8266 being a WiFi module with a basic UART interface. But later it became clear that it’s powerful enough for embedded system. It’s essentially a module that can be used for running full-fledged applications. Espressif realized this as well and released an SDK. As first versions go, it was full of bugs but since has become significantly better. Another SDK was released which offered FreeRTOS ported to ESP. Here, I want to talk about the non-OS version. Of course, there are third-party firmwares which offer support for script language to simplify development (just Google for these), but ESP8266 is still a microchip (emphasis on MICRO) and using script language might be overkill. So what we […]
