About the adventures of connecting an Bluetooth /Wifi M.2 card via regular USB to my Mac.
Bluetooth SIG added support for Intel BE200 Bluetooth/Wifi cards to PTS - connection options in our blog: bluekitchen-gmbh.com/usb-adapter-fo…
Finally able to control our living room projector remotely via Matter by having an ESP32-C3 press the Power button and monitor the LEDs :) github.com/mringwal/proje…
Finally managed to record a video and write about AVRCP Cover Art from iPad on @pimoroni Cosmic Unicorn based on on @Gadgetoid 's spectrum analyzer demo: bluekitchen-gmbh.com/avrcp-cover-ar…
Anybody managed to access iOS GATT Services over an existing BR/EDR Connection? Want to read the battery, but only get 'connection refused: no resources available' when connecting to ATT PSM 0x1f. #CoreBluetooth
Need to access a device or sensor with a common bus interface like I2C, I2S SPI, SDIO and friends from your desktop system, please checkout our new github.com/mringwal/multi… project.
The BL654 USB dongle from Laird Technologies is back-ordered until Summer 2022 - use an nRF52840 USB dongle with Bluetooth PTS instead
New blog post on using nRF52840 USB dongle with Bluetooth PTS: bluekitchen-gmbh.com/bluetooth-pts-…
Another simple KICAD design, this time with black text on white mask to match the STM32 Nucleo board.
New Semtech SX1280 breakout board for our experimental BLE link layer. github.com/bluekitchen/sx…
My first experience with USB on an embedded MCU...
New blog post on using an STM32 F4 Discovery board with an USB Bluetooth Dongle to boot BTstack: bluekitchen-gmbh.com/btstack-stm32-…
Finally got around to play with circular/ping pong DMA and manual CTS/RTS to continuously receive data without loosing bytes.
New blog post explores how to correctly receive Bluetooth HCI packets on UART data without RTS/CTS: bluekitchen-gmbh.com/msp432p401r-cc…

GATT over BR/EDR seems cool for firmware updates, or sending/retrieving larger files from/to iOS.
iOS 13 will support GATT over BR/EDR - a.k.a. CoreBluetooth Classic (developer.apple.com/videos/play/ww…). You can check it out with BTstack -> groups.google.com/forum/#!topic/…
lwIP is compact and fun...
New example of running lwIP HTTP + DHCP server on top of BTstack's PAN implementation - provide a Web app for your device instead of native apps... groups.google.com/forum/#!topic/…
@dennismantz Sounds good. Any idea already where the WizardsOfDos CTF is located :) ? Don't see it at the 'Assemblies' page.
@dennismantz just saw your mrmcd talk. I'd be curious if InternalBlue could be used to built a full BR/EDR sniffer. Are you around Days 1-3 at 35C3 as well? I'd be happy to say hi.
Arrived in Leipzig today for 35C3. DM me if you're curious about the Raccoon BLE Sniffer or BTstack in general.
New project with Dirk: the open-source BLE Sniffer called Raccoon for Nordic's nRF5x line. Captures unencrypted connections incl. LE Data Length Extensions. Use 3 sniffers to track all advertisement channels. Encryption, 2M and Codec PHY will come soon! github.com/bluekitchen/ra…
70 devices based on our P44-DSB-xx2 experience now power the ETH Digital Platform, shown to the public for the first time this weekend: (Image © Jon Etter) plan44.ch/media/ETH_DP_s… plan44.ch/custom
A friend pointed out a stupid bug in the POSIX version of our Broadcom chipset driver and also helped to figure out how to use the 'mailbox' firmware interface to properly power cycle Bluetooth. Et voilà...
New BTstack port for @Raspberry_Pi 3 and @Raspberry_Pi Zero W using built-in BCM4343 Bluetooth/Wifi Controller: github.com/bluekitchen/bt…
@spirilis lol. Most Bluetooth Controllers and even ready-to-use Bluetooth modules have the pads below, so reflow soldering is really lurking behind the corner...
