Wi-Fi Performance Comparison for Android Media Players and HDMI Sticks

If you’re mainly using your Android mini PC or STB to stream videos over the web or your local network, Wi-Fi performance is actually more important than CPU performance, and I’ve recently had quite a few issues with Wi-Fi with both T428 (RK3188 / Broadcom Wi-Fi module) and CS868 (AllWinner A31 / Realtek Wi-Fi module), which were only fixed after upgrading my router firmware. So I’ve decided to re-test most of the mini PCs I own with the upgraded router firmware, and the number are highly confusing, and I found out there’s probably be no easy to way to estimate the overall Wi-Fi performance of any device, and it’s most probably highly dependent on the router used, and its firmware version. My router is TP-LINK WR940N, a 300 Mbps Wireless N router with three antennas. Since I bought it, I had never upgraded the firmware (3.9.18 Build 100104 Rel.36350n) from […]

Adding Wi-Fi to Emcraft Systems K70 SoM

Emcraft Systems K70 SoM is a system-on-module powered by Freescale K70 Cortex M4 micro-controller with enough RAM (64 MB) to comfortably run uClinux. They used to charge $99 for their uCLinux BSP, but it’s now free of charge, and the company also provides full hardware and software documentation, including a getting started guide, schematics and BoM for the baseboard, application notes and more… Many of their clients want to use Wi-Fi with K70 SoM, and it can easily be done by using Wi-Fi USB dongles based on Ralink RT5370 chipset such as D-Link DWA-140 (H/W rev B3) or Comfast CF-WU815N. Emcraft has provided detailed instructions to do so with K70 SoM, their latest baseboard (SOM-BSB-EXT) and a demo image based on their uClinux BSP. I’ll summarize the instructions to use K70 SoM as a Wi-Fi access point below. Connect the baseboard and K70 SoM with an Ethernet cable, a mini […]

$14 Marstek MPR-N9 WiFi/3G Router with 2,400 mAh Battery

One of my readers (Onebir) brought Poray M3 mini Router to my attention a few days ago, as it just cost $17 at the time (now over $20) and OpenWRT developer Squonk seems very interested about it since it features microSD and SD card slots missing in TL-WR703N. However, the device only has 16 MB memory which makes it somewhat difficult to run OpenWRT, or at least some of its features. But today, I’m not going to talk about this. Mentions of Poray M3 router came in HAME MPR-A1 OpenWRT forum thread, and I discovered a new (to me) type of low cost, small form factor device: portable Wi-Fi/3G routers. Those devices are about the size of android mini-PC and contain the chips to handle Wi-Fi, USB host (for external 3G dongle), and comes with a built-in battery so that you can use them anywhere (beach, mountain, car…), as long […]

Digi Launches XBee Modules Examples Website To Get Started with IoT Development

Digi International has launches an example section on their website to showcase what can be done with their XBee 805.15.4, ZigBee and WiFi Modules, as well as their IoT gateway. They provide examples to use different type of sensors, control lights, motors, and more. They show demos on the website and explain how each components can be linked together, hooked to computers and connected to the internet. They currently just have a few tutorials only, but plan to add more overtime: Basic XBee 802.15.4 & Zigbee Chat 802.15.4 PWM and Digital Output with an LED 802.15.4 Digital Input with a Button 802.15.4 Analog Input with a Potentiometer Light Switch XBee – A wireless wall switch that can control lamps, fans, motors or your homemade robot The first four examples look good to get started, but the Light Switch XBee is the most interesting, and they describe 8 steps to show […]

Android Transporter Enables WiFi Display Mirroring (similar to Miracast) of Android Devices

E.S.R.Labs is a German embedded software company mainly working for the automotive industry. But this time, they’ve started to work for the consumer market with Android Transformer, a software solution that can mirror an Android display to another Android device display via Wi-Fi in a similar fashion to what WiFi Miracast will do. Eventually, the company plan to make Android Transporter compatible with Wi-Fi Miracast, but in the meantime they rolled out their own solution by taking advantage of H.264 hardware encoders and decoders on Galaxy Nexus S and the Raspberry Pi. If they use standard APIs, I assume any hardware running Android that with H.264 hardware encode/decode should support their platform. I hope it will be work on (or be ported to) CX-01 mini PC which can be bought as low as $40 inc. shipping. It would make an even cheaper hardware than the Raspberry Pi (Up to 33% […]

Texas Instruments Unveils Wi-Fi CERTIFIED Miracast Video Streaming Solution Based on OMAP 4

In my previous post, I wrote about Marvell announcement of its new 802.11ac chipset (Avastar 88W8897) that will be Wi-Fi CERTIFIED Miracast. But it’s not the only company for such solution, as Texas Instruments has also announced the availability of a complete solution for mobile devices designed to support Wi-Fi CERTIFIED Miracast, based on the Wi-Fi Alliance Wi-Fi Display Specification that enables users to reliably display high definition content from a mobile device onto a larger screen over a secure, low-latency, wireless network connection. The Miracast certification program defines a standards-based solution for streaming video and audio content over a peer-to-peer Wi-Fi Direct wireless network. TI solutions will leverage OMAP processors and its WiLink connectivity solutions to provide a Miracast platform. This new solution will be available later this year to power mobile phones, tablets, HDTVs, projectors and audio receivers. Texas Instruments solution will provide the hardware and software resources […]
