Module provides BLE connectivity between tablets and cloud

by Alice Matthews@ electronicspecifier.com discuss about MBN52832 a BLE module:

A Nordic-based BLE module has been released by Murata. The latest MBN52832 device consists of Nordic Semiconductor’s nRF52832 IC, a 32MHz crystal for timing, and an on-board antenna. Additionally, it contains pins for an off-board omni-directional antenna and a NFC antenna. The module provides a Serial Port Interface (SPI) and UART interface to Nordic’s nRF52832 ARM Cortex M4 processor.

hackaBLE uses the Nordic nRF52832 which in turn is based on an ARM Cortex-M4 core. So you can really program it with any ARM compatible programmer. We do have a convenient solution though, in the form of our Bumpy blackmagic probe compatible SWD debugger and our PogoProg.

Alzheimer’s Wearable Assistant

A smartwatch with fall and location detection, reminders and more, designed to help you or your loved one with Alzheimer’s!

When I saw Infineon’s Sensor Hub Nano, it appeared to be a good candidate in such a project, because of its very small size and BLE capabilities. With the accurate pressure sensing, it could be used to detect if the patient has fallen and also tell where exactly the patient is in the house.

IoT cloud development kit is Wi-Fi and BT/BLE-ready

Together with partners Cypress Semiconductor and Murata, distributor Future Electronics has launched the Nebula IoT Development Kit, an IoT cloud ready board that allows developers to quickly prototype and deploy their IoT ecosystems. by Julien Happich :

Wireless connectivity is supported by the Murata 1DX module, which is powered by the Cypress CYW4343W Wi-Fi and BT/BLE combo SoC.

The SoC includes a 2.4 GHz WLAN IEEE 802.11 b/g/n baseband/radio and Bluetooth 4.2 support. In addition, it integrates a high-performance power amplifier (PA), a low-noise amplifier (LNA) for best-in-class receiver sensitivity, and an internal transmit/receive (iTR) RF switch, further reducing the overall system cost and 1DX module size

Bluey, BLE Development Board Supports NFC

Development boards are assistant tools that help engineers and enthusiasts to become familiarized with hardware development. They simplify the process of controlling and programming hardware, such as microcontrollers and microprocessors.

Electronut Labs, an embedded systems consulting company, had produced its new BLE development board “Bluey” with a set of useful sensors and NFC support.

Bluey is an open source board that features the Nordic nRF52832 SoC which supports BLE and other proprietary wireless protocols. Bluey has built-in sensors that include temperature, humidity, ambient light and accelerometer sensors. Also, it supports NFC and comes with a built-in NFC PCB antenna.

The nRF52832 SoC is a powerful, ultra-low power multiprotocol SoC suited for Bluetooth Low Energy, ANT and 2.4GHz ultra low-power wireless applications. It is built around a 32-bit ARM Cortex™-M4F CPU with 512kB + 64kB RAM.

Bluey Specifications:

  • Nordic nRF52832 QFAA BLE SoC (512k Flash / 64k RAM)
  • TI HDC1010 Temperature/Humidity sensor
  • APDS-9300-020 ambient light sensor
  • ST Micro LSM6DS3 accelerometer
  • CREE RGB LED
  • CP2104 USB interface
  • 2 push buttons
  • Coin cell holder
  • Micro SD slot
  • 2.4 GHz PCB antenna
  • NFC PCB antenna

Bluey can be programmed using the Nordic nRF5 SDK. You can upload the code with an external programmer such as the Nordic nRF52-DK, or the Black Magic Probe firmware on STM32F103 breakout. But, within the built-in OTA (over the air) bootloader, you can upload the code directly using a PC or a phone.

The sensors on the board require a minimum of 2.7 volts to function properly, and the maximum power is 6 volts. Bluey’s design offers three different ways to power it, all of them have a polarity protection:

  1. Using the 5V micro USB connector (which also gives you the option to print debug messages via UART).
  2. The + / – power supply pins which can take regular 2.54 mm header pins, a JST connector for a 3.7 V LiPo battery, or a 3.5 mm terminal block.
  3. A CR2032 coin cell for low power applications.

You can use Bluey for a wide range of projects. The BLE part is ideal for IoT projects, or if you want to control something with your phone. The nRF52832 SoC has a powerful ARM Cortex-M4F CPU, so you can use this board for general purpose microcontroller projects as well.

Bluey is available for $29 for international customers from Tindie store. Indian customers can purchase it from Instamojo store. There are also discounts for bulk purchases. For more information about the board visit its github repository, where you will find a full guide to start and a bunch of demo projects.
