Android Patch Brings Bluetooth SBC Codec Audio Quality on-par with aptX

Android Bluetooth SBC HD Audio

In the context of CNX Software’s topics, SBC usually stands for “Single Board Computer”, but SBC also stands for “SubBand Codec“, a standard and mandatory Bluetooth codec which is supported by all headphones, portable speakers, car head units, and basically everything that plays audio over Bluetooth. SBC is known as a basic and low-quality Bluetooth codec, so people will often recommend using other codecs such as aptX, AAC or LDAC wherever possible, but ValdikSS has submitted a patch for Android which improves Bluetooth SBC codec audio quality on most existing devices, allegedly making it as good as the high quality aptX HD codec. ValdikSS explains this basically works by increasing the bitrate: My patchset bypass Android Bluetooth stack limitations and increase bitrate from stock 328 kbps to 452 or 551 kbps, depending on device speed capabilities. It’s already merged into LineageOS 15.1 and 16.0, Resurrection Remix and crDroid alternative Android firmwares. You’ll get the full detailed technical explanation in “Bluetooth …

Silicon Labs Demonstrates Bluetooth 5.1 Location Technology (Video)

Bluetooth 5.1 Location Base Station

Recently there are been advancements related to precise indoor positioning with the announcement for Bluetooth 5.1 and 802.15.4z. Both can provide 1 to 10 centimeters accuracy with minimal lag, and Bluetooth 5.1 achieves this through Angle of Arrival (AoA) and Angle of Departure (AoD) features and an antenna array. I had never seen the new feature in action, but Silicon Labs recently demonstrated Bluetooth 5.1 location technology at Arrow IoT summit with a DMX-512 connected light following a person carrying a Bluetooth 5.1 tag. It looks fairly accurate, and it does not have a 3-6 seconds lag like previous solutions based on earlier versions of Bluetooth? So what does one need to enable Bluetooth 5.1 location finding? First, we’ll need a Bluetooth 5.1 base station with an antenna array, The one used above includes a 16 antenna array (4×4 grid) used to calculated angles of departure and arrival and ultimately the position and direction of the beacons. The Silabs Blue …

Newyes SyncPen Bluetooth Pen Digitizes Your Handwriting to the Cloud (Crowdfunding)

Neweyes SyncPen

When I first found out about SERVO K07 bluetooth pen last month, I initially hoped it would allow users to digitize their handwriting or drawing and synchronize it to their phone or cloud, but it was not to be the case and instead it was just a 6-in-1 phone/pen/audio player/audio recording/camera/flashlight. But Newyes SyncPen does exactly that: it allows you to write on paper or a writing pad while digitizing your creation on the fly, and storing the result in the cloud. It works thanks to a tiny camera embedded in the pen capturing data at 200 fps. Newyes SyncPen hardware specifications: Connectivity – Bluetooth 4.2 Memory – 32MB, enough to store 800 pages of A5 paper content Pressure levels – 1024 Tiny camera @ 200+ fps Audio – Microphone Battery – 3.4V / 260 mAh Lithium Polymer battery good for about 8 hours; 1.5 hours charging time Dimensions – 16.35 x 1.33 ∅ cm Weight – 22 grams For …

Aconno Bluetooth Beacons Come with Various Sensors, Nordic Semi nRF52 BLE SoC

Aconno Bluetooth Beacons

We first covered products from Aconno is 2017 with their Bluetooth LE development board powered by the company’s ACN52832 BLE module based on Nordic Semi nRF52832 ARM Cortex-M4 multi-procotol wireless SoC. Since then they’ve launched several small Bluetooth beacon modules based on ACN52832, and the company has what they call a presale promotion until May 21st, but it looks really like a group buying event for their existing BLE modules where the price goes down as more people purchase modules. Six Bluetooth modules are offered: acnSENSA multisensor Bluetooth tag with temperature, light, humidity, barometer, accelerometer, magnetometer, gyroscope acnBEACON programmable Bluetooth tag acnACT BLE beacon with button and RGD LED, magnetometer, phototransistor acnNFC programmable Bluetooth tag with NFC tag emulator acnRANGE distance measuring beacon with time-of-flight sensor acnFIND Bluetooth smart tag with LED, sound and accelerometer All modules come with a replaceable CR2450 battery, and IP65 enclosure. Pricing currently ranges from 15.96 Euros (Net) to 29.40 Euros (Net), but price may …
