MakerSpot CC2640 is a $20 Bluetooth 5 LE USB Dongle

Bluetooth 5 was announced in May 2016 with four times the range, twice the speed of Bluetooth 4.0. Since then SoCs, development boards, and smartphones have been announced with Bluetooth 5, but so far I had not seen any Bluetooth 5 USB dongle to add the new Bluetooth version to existing computer or boards. While I’ve not been able to find a consumer grade Bluetooth 5 USB dongle yet, today I found out something close it to with MakerSport CC2640 USB dongle / board based on TI CC2640 chip.

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) based on LPC54018 Arm Cortex-M4 core @ 180MHz with Longsys …

UDOO BLU and BLU SENSE IoT Modules Integrate Bluetooth LE, Zigbee, and 6LOWPAN Connectivity

UDOO is known for their Linux boards based on NXP and Intel processors for makers and the education market such as UDOO NEO or UDOO x86, but the company has now developed UDOO BLU and BLU SENSE battery powered modules based on Texas Instruments CC2650 ARM Cortex M3 microcontroller, both with Bluetooth LE, Zigbee, and 6LOWPAN connectivity, and the SENSE model adds some extra sensors.

Texas Instruments CC3200 WiFi SensorTag is Now Available for $40

Texas Instruments launched SensorTag in 2013, and at the time there was just a Bluetooth 4.0 LE version with 6 different sensors. I bought one for $25 at the time, and tried it with a Raspberry Pi board and a BLE USB dongle. Since then, the company has launched a new multi standard model (CC2650STK) supporting Buetooth low energy, 6LoWPAN, and ZigBee, and has just started to take orders for CC3200 WiFi SensorTag for $39.99, which seems expensive in a world of $2 ESP8266 modules.

Energympro EP-SH09 Fitness Tracker Review

Energympro EP-SH09 is a strapless fitness tracker with an heart rate monitor and Bluetooth 4.0 LE for synchronization with your smartphone, in the first part of the review, I took some picture of the device, and expressed my opinion about the build quality. I’ve now played close to two weeks with the tracker, so I can share my experience with the device. Bear in mind that this was still considered an engineering sample, so the company will likely on some of the issues I encountered before it ships to the general public or resellers. A capacitive touch area just under the display is used to cycle through 7 watch faces: Time, Date, Bluetooth (Icon will change to a chain when connected), step count, distance, calorie count, and heart rate monitor. It works well enough, but there are a couple of point that you may want to be aware. The display will stay on for about 15 seconds after the last …

M2.COM is a Standard for IoT Sensors Based on M.2 Form Factor

The IoT ecosystem really feels like a jungle now, not because of a lack of standards, but because everybody thinks about doing their own, so we’ve ended up with a wide range of communication protocols, initiatives, and consortia, and it will take some time until the winners and losers are sorted out. One the of the latest standard is M2.COM platform form factor for sensors that “adopts the standardized M.2 form factor and is defined as an evolutionary module that combines general wireless connectivity with additional built-in computing ability powered by MCU”. M2.COM architecture diagram above describes both software and hardware requirements, but the specifications themselves only define the form factor, as well as mechanical and electrical characteristics: Consistent with M.2 standard Module size: 22 mm x 30 mm PCB thickness: 0.8 mm ± 10% Pin count: 75 pins Module input voltage: 3.3V DC-in Connector mating force: 30N Maximum Connector current rating: 0.5A / Power contact Connector operation temperature range: …
