Multi-stream and broadcast audio features part of the Bluetooth LE Audio standard have been given a brand name by the Bluetooth Special Interest Group (SIG). Meet Bluetooth Auracast broadcast audio, or simply Auracast for shorts. As a reminder, Bluetooth Audio LE broadcast enables an audio transmitter, be it a smartphone, laptop, television, or public address system to broadcast audio to an unlimited number of nearby Bluetooth audio receivers that could be speakers, earbuds, or even hearing devices. Auracast broadcast audio will let users invite others to listen to the same music without disturbing others around them, for example, a group of friends could listen to the music in the subway or on a bus through Auracast-enabled earbuds. Auracast will also be useful in public places, where for instance, users could listen to the audio from muted televisions at airports, gymnasiums, or train stations, and public announcements (e.g. gate changes, boarding […]

OSM Size-0 solder-on LGA module comes with ESP32 WiFi & BLE MCU
German embedded systems company iesy’s ESP32 OSM-0F is an ESP32-based solder-on LGA system-on-module that complies with SGET OSM Size-0 (30x15mm) form factor, offers WiFi and Bluetooth connectivity, and more. The SGET Open Standard Module (OSM) standard defines four module sizes, namely Size-0 (30x15mm), Size-S (30x30mm), Size-M (45x30mm), and Size-L (45x45mm), and all the modules we’ve covered so far were powered by a Linux-capable processor. But it’s more challenging, albeit not impossible, to design a Linux-capable OSM Size-0 module, and that form factor is better suited to microcontroller-class chips like ESP32. (Technically, ESP32 can run Linux, but it’s more for show that any practical applications) ESP32 OSM-0F specifications: Microcontroller – Espressif ESP32 dual-core Xtensa LX6 MCU @ 240 MHz with 512KB RAM, Wi-Fi 802.11 b/g/n and Bluetooth/BLE Storage – 32 Mbit SPI flash Antenna – u.FL connector 188 LGA contact points with Storage – SDIO Networking – 1x 10/100M Ethernet (RMII), […]
Panfrost now offers a fully-conformant OpenGL ES 3.1 implementation for Mali-G57 (Valhall) GPU
The Mali-G57 GPU part of the Valhall family, and found in several Arm processors such as MediaTek MT8192 and MT8195 SoC powering some Chromebooks, is now supported by the Panfrost open-source driver with a fully-conformant OpenGL ES 3.1 implementation. Last year, Collabora updated Panfrost with support for OpenGL ES 3.1 on Midgard (Mali T760 and newer) and Bifrost (Mali G31, G52, G76) GPUs, and also announced having started working on Valhall GPUs. One part of the work was done in the summer of 2021 with some reverse-engineering work on Mali-G78 GPU’s instruction set, and this has culminated with a fully-conformant OpenGL3.1 for Mali-G57 GPU. Interestingly, it’s not been released by Collabora directly, but through an organization called “Software in the Public Intenerest, Inc.” (or SPI for shorts) which happens to be a non-profit organization incorporated on June 16, 1997, and described as: a non-profit corporation registered in the state of […]
