Starting with this post, you’ll find on my website a tutorial about the new Arduino Yun: I’m going to blog about my experiments with that board and show its features through real examples… today you’ll learn how to connect it to your wifi network!
Yun and wifi
One of the most useful features Arduino Yun has is the ability to connect to wired (Ethernet) or wireless networks without the needing of an external shield.
I decided to supply my Yun using an external micro USB power supply (power supplies for modern cellphones works fine):
By default, Arduino Yun acts as an access point, broadcasting an unprotected wifi network with Arduino Yun-xx SSID:
After having established a connection, your PC obtains an IP address on the network 192.168.240.0/24:
You can reach the administrative interface of Arduino Yun pointing a web browser to the address http://192.168.240.1. The default password is arduino:
After having logged in, click on configure:
You can change the board’s name (in the screenshot I chose Yun-Luca), the password, the timezone and connect the Yun to one of the wireless networks it detected:
After a reboot, the board will be connected to your network!
Upload via wifi
Now you can use a new feature of Arduino Yun: the ability to upload a sketch using the network, without the needing to connect the board to your PC using a USB cable.
Open the IDE (warning: you must download the latest version, at the moment I’m writing 1.5.4r2) and choose Arduino Yun as your board.
The IDE will scan your network searching for Yun boards and, under the port menu, will display your board and its IP address:
You can now compile and upload your sketch as usual… when the upload process will start, you’ll be prompted for the Yun password:
SSH terminal
You can also connect to your Yun in text mode, using an SSH client (for example PuTTY per Windows)… in the next posts you’ll discover why this can be useful:

ZigBee device list
Motion detector Smoke sensor Door detector Water Detector Temperature and Humidity Sensor CO Sensor These ZigBee node devices support ZHA standard protocol.
Linker ZigBee gateway module is one kind of Linker modules which can communicate with up to 32 ZigBee node devices. It is powered by Marvell 88MZ100 ZigBee microcontroller SoC chip. This ZigBee offers advantages for many application scenarios, including lighting control, smart metering, home/building automation, remote controls and health care applications.
Tutorial
we will show how to interface Deepcam ZigBee sensors using the Linker ZigBee gateway.
Prerequisites
Commands to communicate with ZigBee sensor
1. Set Permit Join
Attribute Name Type Note CMD Length Uint8 0x02 CMD ID Uint8 0x75 Permit Join Uint8 0x00 – Always off; 0xFF – Always on; Other values – Turn on permit join for a period of time Example
- Send: [UART] 02 75 1E
- Success response: [UART] 02 8A 00
Note: How to reset ZigBee node device and let it join into the ZigBee gateway？
- Insert the pin to the reset hole and hold, until the green light is blinking very fast.
- If the light blinking is not fast, just release the pin and insert it again until it is blinking very fast.
- This will set the ZigBee sensor into reset mode.
- Send Set Permit Join commands to join
- After a while, gateway will get the response–** New Device Joined Indication**
2. New Device Joined Indication
Sent after ZigBee gateway sends Transport Key to the joining device or received a ZDP Device Announcement.

We are seeing an increased need to track a object in real time and view its position on a mobile phone. There are many different places that users want to install the GPS tracker, but a rigid enclosure like what the market currently has cannot meet all the requirement. Openhapp offers this DIY GPS tracker kit to service the DIY market where users can use encosures, batteries, antenna to fit their need. This GPS tracker posts its position and battery level to LinkSprite.io at a configurable time interval, a mobile APP is also provided to get the position and battery level from LinkSprite.IO and show the location on the mobile APP.
To add the device to a user's account is done by using the mobile APP to scan the QR code supplied with the kit.
If you find that this GPS tracker doesn't fit your need exactly, please contact us and we can custom make for you.NOTE:
This GPS tracker uses GPRS, and AT&T doesn't offer this service anymore. We have tested with T-Mobile.Connectors:
- 1 - MiniUSB interface. This is for power supply and can be used to power the board or charging the battery if the battery is attached. With the UART to USB adaptor, it can also be used to communicate with he GPRS/GPS module.
- 2- SWD programming header
- 3- Power on/off button
- 4- GPRS/GPS module
- 5- GPS antenna connector
- 6- GSM antenna connector
- 7- Bluetooth antenna connector
- 8-DS4 power on indicator
- 9-DS3 GPS acquire location success indicator
- 10- DS2 Reserved
- 11- DS1 Charing indicator

The Mbed BLE Sensors tag is a bluetooth 4.0 BLE sensor development board that is powered by Mbed. It integrates powerful devices, such as NRF51822, LIS3DH ,BMP180, buzzer, and dual-color LED. It also embeds an mbed compatible programmer to make program and download application very convenient.
The mbed BLE sensors tag is consisted of two modules: one is a bluetooth 4.0 BLE sensors tag powered by NRF51822 which is a Bluetooth Low Energy & 2.4GHz Wireless SOC. This mbed BLE sensor tag is mbed-enabled device which simplifies and speeds up the creation and deployment of bluetooth devices based on ARM micro-controllers. There is an mbed library supporting BLE sensors tag which provides the C/C++ software platform and libraries, and can speed up your BLE application development.
The other one works as a programmer like Jlink, but it is compatible with ARM’s mbed. It greatly simplifies the programming process. You just copy the compiled hex file to an emulated disk, which is recognized by PC when you plug this programmer into the PC and the programmer will automatically download the program into BLE SENSORS TAG without any other setting.
How to use debug port to quickly access pcDuion8 Uno
in Feedback/Comments
Posted
There is a debug port on pcDuino8 Uno which can used to access system directly as command line mode. You just only use a USB UART cable to connect to this port, when system is up, system initialization information will print to this port and also you can use it to log in Ubuntu. It seemly like an Linux terminal and you can control the whole system without screen, keyboard or mouse. Very convenient, isn’t it?
The following part will tell you how to use this debug port.
1. Get a USB UART cable
I use this PL2303 USB UART cable, and the details has been shown in the following table.
2. Install Drivers on PC（Windows as example）
Download the PL2303 Windows driver and install it.
3. Connect
One port of USB UART cable is connected to PC USB port。Another pins are connected to debup port on pcDuino8 uno.
4. Configure the Serial tool
Open Device Manager to get which COM port has been recognized by PC.
Open a serial tool(take Putty as example) and configure it:
Serial line :COM11
Speed:115200
Then click “Open” button.
Power on pcDuino8 Uno, the log information will print on the window.
At the end, it directly login ubuntu as root, and you can input shell command to control the system.
