Since the traditional smart lighting is mainly WiFi modules, the solution of connecting to the Amazon cloud through a private cloud has many drawbacks: high cost, complex distribution network, and large power consumption.
Based on these flaws, the further development of smart lighting and the user experience are limited. In particular, smart LEDs also need docking between various dazzling clouds, which not only increases cost and reduces stability, but also is more like for the cloud, collecting user information and other things that are not related to users, and there is no other meaning. In order to open a light bulb, you also need a cloud, and even a cumbersome distribution network and other fierce operations, think about it is a bit ridiculous. Smart lighting in the true sense of the word is the need to get rid of these meaningless, anti-human usages.
The previous 10-piece WiFi module now only needs more than 2 yuan of Bluetooth chips to complete, which provides an opportunity for the popularization of intelligence in the extremely demanding LED field.
Lenz Technology launched the Bluetooth BLE5.2 chip ST17H66 to help Amazon Bluetooth direct light.
Lenz Technology - Amazon Direct Connect Slideshow Solution
Lenz Technology launched the latest Amazon direct connection slide program, using the latest ST17H66 Bluetooth BLE 5.2 chip, the slide light can be connected to the mobile phone Amazon Alexa through Bluetooth. Amazon Alexa supports a variety of mode switching, manual and automatic color grading, music rhythm function, support wireless switch, time switch function, free control; at the same time can control multiple slide lights and other program features.
Key features
Amazon Alexa slide dimming mode control
Amazon Alexa slide light dimming intensity control
Amazon Alexa Slides custom color controls
Amazon Alexa slide music rhythm control
Amazon Alexa slide timer switch control
Scenarios
Home: LED slide lights can be used in aisles, bedsides, bookcases, cabinets, wine cabinets, indoor stairs, etc. to make lighting effects, which are used to set off the atmosphere of the entire house layout.
Bar: As these places are set off by the atmosphere of lighting, the atmosphere of the entire place can be designed through the design of the hallucinator lights.
Shops: Interior decorations and the exterior of the shop can also be used to decorate the effect with hallucinators, highlighting the shop name and goods.
Scheme specifications
Using ST17H66 Bluetooth BLE5.2 chip, it is stable, mature and has been commercially used
Low cost and can be combined with existing products
The development cycle is short, all the basic development has been completed, and only the user interface and structure need to be developed
ST17H66 Bluetooth BLE5.2 chip
ST17H66 Bluetooth BLE5.2 chip is the latest 16-foot Bluetooth BLE chip from Lenz Technology, with 256KB Flash + (96KB ROM) + 64KB SRAM, the Bluetooth protocol stack is cured, and it no longer occupies Flash space. 64KB of SRAM, partitioned to save more user data while in standby, can set up large-capacity buffers, and supports more complex functions. Ad hoc networking applications that comply with SIG specifications. Includes multi-node control, as well as 2 masters and 4 slaves working simultaneously.
The biggest advantage is the reduced power consumption. The previous generation of Bluetooth receives peak current >13mA; The MCU consumes ~0.5mA/MHz; the average current in low-power mode >40uA. The new Bluetooth receives a peak current of 8.6mA, the power consumption of the MCU
Lenz Technology has independent research and development of radio frequency and Bluetooth low energy BLE5.2 chip and has global intellectual property rights, for the AIoT Internet of Things field and individual consumers, to provide Bluetooth master control fully integrated chip "hardware and software commonality" solution and core devices, supporting a full range of APP software platform custom development. The designed Bluetooth chip solution is applied to smart wearable devices, Bluetooth indoor navigation, smart home, medical health, sports construction, data transmission, remote control, personal peripherals and AIoT Internet of Things and other scenarios.
The latest Bluetooth chip ST17H66 (SOP16) equipped with a high-performance and low-power 32-bit processor supports BluetoothLE and SIG MESH multifunctional Bluetooth 5.2.
