Aistin Blue Bluetooth LE Development Boards

 

top

Aistin Blue boards are specifically designed for low energy, battery operated wireless IoT and wearable solutions. These small, round devices measure only 32 mm in diameter, or 27 mm, if screw pads and trace points are not needed, and are as thin as just 4.2 mm.

It is a very integrated and simple-to-use modular sensor system. The system has Bluetooth LE with an integrated crystal antenna, keeping it compact and avoiding external components.

Blue boards work out-of-the-box with an Android application. Together with this application, Blue can be used immediately as data logger; sensor readings can also be seen instantly on the screen. Size matters, Blue is small enough for wearables, including wrist-worn devices.

Blue boards include sensors for detecting 3D-acceleration, 3D-magnetism, 3D-rotation, humidity, air pressure and temperature; even more functionality is available, using add-on boards and flexes from the Aistin family. More info about available variants will be available soon.

For product developers, sensor drivers are available at no charge. Firmware programming is easy with Nordic Semiconductor's tool set. Blue SW can be also developed with ARM MBED. Android applications, both Aistin Blue sensor viewer (Basic4Android) and Aistin Blue data logger (Java) example source codes are available also for free.

We at iProtoXi use Aistin Blue as a platform for customer projects, where we adapt it to perfectly fit the customer's specific needs.

Why Aistin Blue?

  • Time to market advantages; reduced hardware development cost and time, direct Blue use, or customized hardware

  • Well known ARM architecture and development tools

  • Famous Nordic Semiconductor BT-LE system on chip solution

  • State of Art IoT Evaluation and Development Kit

  • Easy to extent solution with custom add-ons and flexes using Aistin Bus24, but keeping the solution still enough tiny to fit wearable size

  • 2Mbit EEPROM Memory for customer application use and sensor data storage

  • Low power consumption

Technical Details

Aistin Blue boards integrate low energy Bluetooth (BLE) with crystal antenna based on Nordic Semiconductor nRF51822, nRF52832 or nRF52840 SOC. See details from "Board Core" table below.

Most Blue variants have also 2 Mbit I2C EEPROM memory.

Aistin Blue boards are equipped with Aistin Bus24 host connectors based on the Aistin Bus24 open standard specification. Board has micro USB connector for data transfer (FTDI) and battery charging, power and charge control, smart switch, and programmable red, green and blue LEDs.

Blue Boards have build-in sensors for detecting motion, humidity, temperature and air pressure. Solution can be extended, but in same time kept still tiny by using Aistinbus24 add-on-boards or flexes. See variants from "Sensors in board" table below.

Aistin Blue supports firmware upload over-the-air via Bluetooth LE. Software development tools are provided by Nordic Semiconductor (downloadable for free). Software can be also developed with ARM MBED. Board supports also Tag-Connect connector less interface (TC2030) for flashing and debugging.

Dimensions: Ø 27/32 mm x 4.2 mm (0.6 mm PCB).

SW development tools

Blue application (firmware) programming is easy with Nordic Semiconductor's tool set. There are options to use Keil or Eclipse IDE. It is possible to develop Blue application (firmware) also with ARM MBED. When using ARM MBED, firmware needs to be flashed to Blue either using DFU (needs ZIP format) or by using debugger and TagConnect -cable.

Note: Aistin Blue sensor viever Android application (B4A) source code is available for Blue customers. Please check SW support table below.
Note: Aistin Blue datalogger Android application (native Java) source code is available for Blue customers. Please check SW support table below.
Note: Aistin Blue datalogger firmware source code (Keil) is available for Blue customers. Please check SW support table below.

Firmware Over the Air Update (DFU) Files

Aistin Blue supports DFU (Device firmware update over the air) -feature. With DFU you can download the latest firmware image to Blue without wires using Bluetooth. For DFU operation we recommend you to use nRF Toolbox application that is available from Android Play -store. See more info at https://www.nordicsemi.com/eng/Products/Nordic-mobile-Apps/nRF-Toolbox-App

Check your board version for right firmware. You can find firmware binarys from "SW support" table uder Firmware - Binary (.ZIP)

DFU insructions

  1. Prepare that you have BT-LE capable Android phone. Android version 5.x.x or later recommended

  1. Download nRF toolbox Ble Android application from Google Play.

  2. Install and open the application. Enable Bluetooth, if asked
  3. Select DFU operation from the application
  4. Download the latest Aistin Blue DFU firmware (like Aistin-blue-BTL3x3-V149.zip) from this page
  5. Select the Aistin Blue DFU firmware in nRF toolbox application
  6. Power on the Blue
  7. Select the Blue from nRF toolbox application
  8. Note: firmware can be updated only in Blue bootloader mode, so you need to keep the Blue power/reset button pressed, until you have started the DFU operation from the application
  9. Note: device BT name may be different during bootloader mode
  10. DFU operation should start, when pressing the "upload" from the application

Tag Connect interface (flashing and debugging)

Aistin Blue supports connector less Tag Connect interface for wired flashing. Tag Connect interface was selected because of zero cost solution in mass manufacturing. Developers can use Tag Connect interface for flashing and debugging either using J-Link debugger or using Nordic Semiconductor reference design kit.

When using Tag Connect interface, please use TC2030-IDC-NL cable (http://www.tag-connect.com/TC2030-IDC-NL).

When using J-Link debugger, you can either use Tag Connect ARM20-CTX 20-Pin to TC2030-IDC Adapter for Cortex http://www.tag-connect.com/ARM20-CTX or you can use iProtoXi adapter for TC2030-IDC (available on request).

TC2030-IDC-NL -cable and iProtoXi adapter for TC2030-IDC

When using Nordic Semiconductor reference design kit debug out, you can use adapter for TC2030-IDC provided by iProtoXi.
