How to Fix Slow GPS Lock on Mediatek MT65xx based Smartphones

I’ve recently purchased ThL W200, an Android 4.2 smartphone powered by Mediatek MT6589T quad core processor, and I’m trying to test a few things including GPS. I’ve enabled access to my location, GPS, and Google’s location service using Wi-Fi and mobile network. In Google Maps, I could get a somewhat accurate position thanks to mobile network location, but it was clear it could not lock GPS. I’ve also tried Nike+ Running, an application that keeps track of your running sessions with GPS, gives you some audio feedback as you run (distance, time and speed), and compares your performance to the average, and your social network friends. When I wanted to start running, the app complained about weak GPS signal, and tried to lock GPS for about 10 minutes, until I decided to give up. So I tried to find a solution, and Google pointed me to an article on Gizchina […]

LightBlue Cortado is an Arduino Compatible Board Programmed Wirelessly via Bluetooth LE (Crowdfunding)

We’ve already seen several Bluetooth Low Energy (BLE) Arduino compatible boards being crowd-funded such as RFDuino and BLEDuino, but there’s now another board designed by Punch Through Design: LightbBlue Cortado. The board is programmed wirelessly directly via Bluetooth LE, instead of USB as in the two aforementioned boards, which means programming via iPad or Android tablets becomes more convenient. Here are the technical specifications of the board: MCU – Atmel ATmega328P @ 8MHz with 32KB Flash, 1KB EEPROM, 2KB SRAM Bluetooth – LBM313 Module with Texas Instruments CC2540, 256 KB Flash. Bluetooth range: 30.5m. Power consumption in sleep mode: 0.9μA I/O – 4 PWM pins, 2 Analog inputs, 8 GPIO, I2C and SPI Sensor – 3-Axis Accelerometer Misc – RGB LED, protoboard section, adhesive backing Power – Coin cell battery. Battery life exceeding one year for low power applications There’s no USB, so the only way to program the board is via […]

ThL W200 Unboxing Pictures and Video

I recently decided I had enough of my Nokia C6-01 phone, and decided to look for a Chinese smartphone with the following specifications: quad core processor, 5″ to 5.5″ display (720p resolution), at least 1 GB RAM, at least 8 GB flash, GPS, Wi-FI and 3G (UMTS) support, all that for about $200. It also had to run Android 4.2.x as I want to give Miracast a try. Ideally, I would also have liked a phone with Bluetooth 4.0 LE in case an Android 4.3 was in the work. But since Bluetooth versions are rather a game of luck in Chinese websites, I did not put too much importance to this last point. I finally went with ThL W200 as it matched my minimum specifications, the price was right, and it got a few people excited over at XDA Developers Forum. I bought the white version for $187.20 on DealExtreme, […]

GalaGreat GalaRing NFC Smart Ring Unlocks Doors, Smartphones, and Exchanges Data

Once upon a time, last August more exactly :), the NFC Ring launched on Kickstarter, and funding was an amazing success. Thanks to NFC technology, the ring is battery-less, and communicates with other NFC enabled devices so that you can unlock your door, unlock your smartphone, share information such as contact details, website links, pictures, etc… The rings will most probably be shipped to Kickstarter wizards backers next month or in January. However, a very similar product called GalaGreat GalaRing G1 has appeared on websites such as GeekBuying and Expansys for about $30.
