Blue family

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

Most of Aistin 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.

Aistin 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 tables below, also sensor datasheet download links are available.

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).

Software / Firmware

Aistin Blue sensor viewer application (Android)

Aistin Blue data logger application

Kionix IoT kit software

Development tools

Software 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.

 

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 “Software/Firmware”.

 

DFU insructions

  1. Prepare that you have BT-LE capable Android phone. Android version 5.x.x or later recommended
  2. Download nRF toolbox Ble Android application from Google Play.
  3. Install and open the application. Enable Bluetooth, if asked
  4. Select DFU operation from the application
  5. Download the latest Aistin Blue DFU firmware (like Aistin-blue-BTL3x3-V149.zip) from this page
  6. Select the Aistin Blue DFU firmware in nRF toolbox application
  7. Power on the Blue
  8. Select the Blue from nRF toolbox application
  9. 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
  10. Note: device BT name may be different during bootloader mode
  11. 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 adapter

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