“Last week I was heads down on BLE scanning and advertising. It’s the first phase of BLE and is incredibly powerful on it’s own. By advertising data directly, one can control a bunch of other devices all at once. I showed a simple demo of one device changing the color of another and then a more complex demo where multiple devices are advertising and multiple are scanning. By moving the scanning devices closer to different advertisers, the color changes to the nearest. To support this I’ve swapped the scan result from a list to an iterator, added rssi filtering and added advertising structure prefix filtering. These early filters reduce the number of Python level memory allocations and simplify the user code. On the library side, I’ve modeled the BLE API after the CircuitPython Register library which uses Python’s descriptor protocol to make defining advertisements declarative with easy to reuse components. This week I’m moving onto advertising designed to facilitate connections and ensuring all of the existing demos Dan has done still work.”
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
