There are now many smartwatches with electro-optic hear rate monitors, but based on my short experience so far, if you want something accurate and reliable, you’d still better use a chest trap. Another potentially more comfortable option would be to use Hexoskin Smart T-shirt, and on top of the usual fitness data (step count, calorie burn, distance and heart rate), also measure your breathing rate and volume. The T-shirt also supports Bluetooth Smart to send back all the data to your smartphone or other devices such as bike computers or smart watches. The company already has Bluetooth Classic T-Shirt, but there latest versions will offer longer battery life and Bluetooth 4.2 LE connectivity. Hexoskin T-shirt 2016 specifications: Bluetooth Smart 4.1 connectivity via Cypress EZ-BLE PRoC module Heart rate, RR intervals, fatigue and stress indicator (Heart Rate Variability). Breathing rate and breathing volume. Activity intensity, peak acceleration, steps and cadence. Analog 256Hz […]
Mediatek Unveils MT2523 SiP for GPS Enabled, Bluetooth LE Wearables
Silicon manufacturers are starting to launch ever more integrated solutions specifically designed for wearables, and after Samsung S3FBP5A bio-processor unveiled a few days ago, MediaTek has launched MT2623 ARM Cortex M4 System-in-Package (SiP) with GPS, Bluetooth LE, and a MIPI DSI interface. Other details are sparse but here’s what the company disclosed for MT2523: MCU core – ARM Cortex M4 GPU – 2D accelerator supporting true colors, per-pixel alpha channel, anti-aliasing fonts, and 1-bit index color to save memory. Connectivity – Dual-mode Bluetooth Low Energy and GPS Display – MIPI DSI and serial interfaces Integrated PMU Battery Life – More than a week (typical) The SiP’s printed circuit board area is said to be 41% percent smaller than competitors’ solutions. MT2523 will be available to manufacturers in H1 2016, and found in active and fitness smartwatches a little later. Thanks to Nanik for the tip.

Makibes F68 is a $35 IP67 Rated Sports Smartwatch with HRM & 7-Days Battery Life
So far my quest for a smartwatch as not been successful, with massive disappointments with both No.1 D3 smartwatch and SMA-Q color e-Paper smartwatch, with the latter completely failing after a week. The next potential candidate is Makibes F68 with similar features as SMA-Q, but instead with a grayscale display, IP67 ingress protection rating which should make it suitable for swimming (apparently not, see comments), as well as a promised 7-day battery life during “normal usage”. Makibes F68 specifications: MCU/Memory/Storage – Not disclosed but it’s supposed to run Nucleus RTOS. Display – 1″ round capacity touchscreen display, 128×128 resolution, always on Connectivity – Bluetooth 4.0 Sensors – 3-axis accelerometer and gyroscope Battery – 180 mAh charged via magnetic connector Dimensions – 38 x38 x 10 mm (aluminum alloy material) Weight – 31 grams IP Rating – IP67 meaning it’s been tested for 30 minutes under one meter of water. The […]
SMA-Q Smartwatch Mini Review and Teardown
I had great hopes for SMA-Q smartwatch, as it features an always on color e-Paper display, a built-in heart rate monitor, and promised 30-day standby battery life, as well as being 30-meter water resistant. But last week, I found out that the latter did not mean waterproof, and instead the watch was rated IP65 that’s only good enough to wash hands and a little rain, but not showering let alone swimming. In the last week, I could play with the watch, and found some serious Bluetooth connectivity issues (with Iocean M6752 smartphone), and I was recommended to upgrade the firmware of SMA-Q watch, and after that my Bluetooth issue have somewhat improve, but everything pretty much went downhill, and the watch is now out of order, and shows no sign of life. So while I was expecting to write a full review, I’ll simply report with experience with the watch […]
Cypress Unveils a $49 Solar Powered IoT Development Kit with Bluetooth LE Connectivity
Cypress Semiconductors has recently launched a Solar powered IoT device kit, with the easy-to-remember codename S6SAE101A00SA1002, featuring the company’s CYBLE-022001-00 Bluetooth Smart module, and S6AE101A energy harvesting power management IC (PMIC) on the main board, as well as all accessories such as a small solar panel, a BLE-USB bridge, and all necessary components and cables.

Omate Rise is a $199 3G and WiFi Smartwatch Powered by Mediatek MT2601 SoC (Crowdfunding)
Most smartwatches sold on the western markets are designed to be smartphone’s companions, and only come with Bluetooth LE connectivity, while we’ve seen many smartwatches (aka watchphones) with SIM card slot originating from China in the past, including the lower end No.1 D3 smartwatch which I reviewed recently. But this may be changing, as Omate is going to launch a new smartwatch called Omate Rise that will include 3G connectivity via a micro SIM card slot, as well as WiFi, Bluetooth Smart, and GPS. Omate Rise specifications: SoC – Mediatek MT2601 dual core ARM Cortex A7 @ 1.2GHz with ARM Mali-400 MP GPU System Memory – 512MB RAM Storage – 4GB flash Display – 1.3″ round muti-touch color display with 360×360 resolution (Innolux) Connectivity – Bluetooth 4.1 LE (A2DP profile), WiFi 802.11 b/g/n, GPS Cellular Connectivity – 3.5G HSDPA (2100/1900 MHz), GPRS / EDGE /GSM (850/900/1800/1900 MHz); micro SIM card […]

Arduino 101 Board Features Intel Curie Module, Bluetooth LE, and Sensors
I’ve recently learned that the battle between the two Arduino teams, namely Arduino SRL (arduino.org) in Italy, and Arduino LLC (arduino.cc) in the US, had taken another turn with Arduino LLC now branding their boards as Arduino in the US, and Genuino in the rest of the world. This may certainly bring confusion to new comers, especially as they have to deal with different version of the Arduino IDE. With that backdrop, Arduino LLC has now introduced Arduino 101 (aka Genuino 101) board powered by Intel Curie module with Quark SE x86 SoC with Bluetooth LE and a 6-axis combo sensor. Arduino 101 specifications: SoC – Intel Curie compute module including an Intel Quark SE x86 32-bit microcontroller @ 32 MHz and an a DSP sensor hub @ 32Mhz with 384 KB flash, 80 KB SRAM (24KB available for sketches), , Bluetooth LE, and 6-axis combo sensor with accelerometer and […]
