Using Link.ONE all-in-one LPWAN development kit with ChipStark, Node-Red, InfluxDB, and Grafana

RAKwireless has sent us a review sample of the WisTrio Link.ONE all-in-one LPWAN IoT development kit with support for LTE-M, NB-IoT, and LoRaWAN connectivity and programmable with the Arduino IDE. We’ve tested the kit with its weatherproof WisBlock Unify enclosure using LoRaWAN connectivity and open-source software packages and frameworks such as ChipStark, Node-Red, InfluxDB, and Grafana. Key features of the Link.ONE kit The Link.ONE kit we’ve received comes with a WisBlock Unify Enclosure (100 x 75 x 38 mm) and a 3,200 mAh/3.7V rechargeable lithium battery which is sufficient when the system is mostly in sleep mode and used to receive data, while not sending information too often. “Link.ONE with BOX” unboxing The following items were very tightly packed inside the box: WisTrio LTE-M, NB-IoT, and LoRaWAN development board Rechargeable lithium battery External Antenna for cellular USB Type-C cable Circular M8 female cable The enclosure is strong with the lid […]

i-Pi SMARC 1200 (MediaTek Genio 1200) devkit tested with a Yocto Linux image

i-Pi SMARC 1200 Yocto Linux glmark2 benchmark

Last weekend I received ADLINK’s i-Pi SMARC 1200 development kit powered by MediaTek Genio 1200 Octa-core Cortex-A78/A55 AIoT processor, checked out the hardware and wanted to install the Yocto Linux image but stopped in my tracks because it looked like I had to install Ubuntu 18.04 first in a Virtual Machine or another computer. But finally, the documentation has been updated to clarify “Ubuntu 18.04 or greater” is required, and I had no problem flashing the image from a Ubuntu 22.04 laptop after installing dependencies and tools as follows:

$ sudo apt install android-tools-adb android-tools-fastboot
$ echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="201c", MODE="0660", $ GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/96-rity.rules
$ echo -n 'SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="201c", MODE="0660", TAG+="uaccess"
SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="0003", MODE="0660", TAG+="uaccess"
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", MODE="0660", TAG+="uaccess" SUBSYSTEM=="gpio", MODE="0660",
TAG+="uaccess" ' | sudo tee /etc/udev/rules.d/72-aiot.rules
$ sudo udevadm control --reload-rules
$ sudo udevadm trigger
$ sudo usermod -a -G plugdev $USER
$ pip3 install -U -e "git+https://gitlab.com/mediatek/aiot/bsp/aiot-tools.git#egg=aiot-tools"

$ sudo apt install android-tools-adb android-tools-fastboot

$ echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="201c", MODE="0660", $ GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/96-rity.rules

$ echo -n 'SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="201c", MODE="0660", TAG+="uaccess"

SUBSYSTEM=="usb", ATTR{idVendor}=="0e8d", ATTR{idProduct}=="0003", MODE="0660", TAG+="uaccess"

SUBSYSTEM=="usb", ATTR{idVendor}=="0403", MODE="0660", TAG+="uaccess" SUBSYSTEM=="gpio", MODE="0660",

TAG+="uaccess" ' | sudo tee /etc/udev/rules.d/72-aiot.rules

$ sudo udevadm control --reload-rules

$ sudo udevadm trigger

$ sudo usermod -a -G plugdev $USER

$ pip3 install -U -e "git+https://gitlab.com/mediatek/aiot/bsp/aiot-tools.git#egg=aiot-tools"

That’s it for the tools. Eventually, the development kit will support three images: Yocto Linux, Android 13 (July 2023), and Ubuntu 20.04 (Q3 2023). So that means only the Yocto Linux image is available from the download page at this time, and that’s what I’ll be using today. We’ll need to connect the micro USB to USB cable between the […]

Using BTT Pad 7 touchscreen display with Raspberry Pi CM4

The BTT Pad 7, or BIGTREETECH Pad 7 in full, is a 7-inch touchscreen display that ships with the CB1 Allwinner H616 system-on-module compatible with Raspberry Pi CM4. The display is mostly designed for 3D printers with its SPI and CAN Bus interfaces, but it can also be used as a standard tablet PC. So today, I’ll switch the CB1 with a Raspberry Pi CM4 Lite module and report my experience doing the conversion and using it as a Raspberry Pi CM4 tablet PC running Raspberry Pi OS, and test it with a 3D printer with Klipper in another post later on. Installing a Raspberry Pi CM4 (Lite) module in the BTT Pad 7 We’ll need the Pad 7, a Raspberry Pi CM4, and a few tools. The first step is to remove the red heatsink by loosening four screws with a 2.0mm hex key, as well as the cover […]

Using ChatGPT for Robotics – Programming myCobot 280 robotic arm with natural language (Sponsored)

ChatGPT AI chatbot can help engineers write programs, and we recently tested it by letting it write a Python program to read data from an I2C accelerometer. But it can be used for more advanced programs and Microsoft Autonomous Systems and Robotics Group used ChatGPT for robotics and programmed robot arms, drones, and home assistant robots intuitively with (human) language. The long-term goal is to let a typical user control/program a robot without having an engineer write code for the system. Microsoft explains that the current robotics pipelines begin with an engineer or technical user that needs to translate the task’s requirements into code for the system. That’s slow, expensive, and inefficient because a user needs to write code, skilled workers are not cheap, and several interactions are required to get things to work properly. With ChatGPT or other large language models (LLM), a user could “program” the robot with […]

How to setup a WireGuard server on Ubuntu for remote login

In this article, we will show you how to set up a WireGuard server on Ubuntu in order to use it for remote login. Introduction to WireGuard First of all, let’s first understand, what is WireGuard? WireGuard is a very simple and fast VPN tool with state-of-the-art encryption. Its goal is to be faster, simpler, more streamlined, and easy to use than IPsec, while avoiding the hassle of large-scale configuration. WireGuard is designed as a general-purpose VPN to run on embedded interfaces and supercomputers in many different environments. Originally released for the Linux kernel, WireGuard is now widely deployed and supported across platforms (Windows, macOS, BSD, iOS, Android). WireGuard is growing rapidly and is already considered the most secure, easiest-to-use, and simplest VPN solution in the industry. Basic Concepts of WireGuard Several basic concepts are involved in WireGuard: Peer: A node in WireGuard. Private key: Each node has its own […]

Using Pico:ed V2 board as a replacement for BBC Micro:bit

We’ve received a sample of the Pico:ed V2 board developed by ELECFREAKS and will show how to use it as a replacement for the BBC micro:bit in a project using CircuitPython. We’ve already covered the board in detail with specifications, block diagram, and pinout diagram before, and it’s basically a Raspberry Pi Pico RP2040 board with BBC Micro:bit form factor including a 17×7 Dot Matrix LED display, some buttons, a buzzer, but no wireless connectivity, relying only on USB instead. CircuitPython firmware installation on the Pico:ed V2 board The board supports C/C++, MicroPython, and CircuitPython programming languages, and for this review, we’ve decided to download the CircuitPython UF2 firmware. Press and hold the BOOTSEL button after having downloaded the firmware file… … and connect the board to your computer using a USB cable before releasing the BOOSEL button on the Pico:ed V2 board, which should then show up as the […]
