Bluetooth solution | Lenz technology Amazon direct connected magic lantern solution

Due to the traditional intelligent lighting WiFi Module based , The solution of connecting to Amazon cloud through private cloud has many disadvantages ： The high cost 、 The distribution network is complex 、 High power consumption, etc .

These defects limit the further development and user experience of intelligent lighting . Especially smart LED It also needs the docking between various dazzling clouds , It not only increases the cost and reduces the stability , More like for the cloud 、 Collect user information and other things unrelated to users , There is no other meaning . To turn on a light bulb , We also need the cloud , Even cumbersome distribution network and other fierce operations , It's a little crazy to think about it . The real sense of intelligent lighting needs to get rid of these meaningless 、 Anti human usage .

before 10 How many pieces WiFi modular , Now it's just a matter of 2 A Bluetooth chip of more than yuan can complete , This is an extremely cost demanding LED The popularization of intelligence in the field provides an opportunity .

Lenz technology launches Bluetooth BLE5.2 chip ST17H66 Help Amazon Bluetooth direct connection lamp .

ST17H66 bluetooth BLE5.2 chip

ST17H66 bluetooth BLE5.2 The chip is the latest product of Lenz technology 16 Foot Bluetooth BLE chip , have 256KB Flash +（96KB ROM）+64KB SRAM, Bluetooth protocol stack , No longer occupy Flash Space .64KB Of SRAM, Partition use , More user data can be saved in standby , You can set a large buffer , Support more complex functions . accord with SIG Standardized ad hoc network applications . Including multi node control , as well as 2 Lord 4 Working simultaneously from .

The biggest advantage is lower power consumption . The previous generation product Bluetooth received peak current >13mA; MCU Power consumption of _{0.5mA/MHz; Average current in low power mode >40uA. The Bluetooth of the new product receives peak current 8.6mA,MCU Power consumption of <90uA/MHz. In low power mode, the average current can be reduced to 20uA}30uA.BLE5 More flexible broadcast packets , Up to 200Byte data ,BLE4 Only 32Byte. Faster transmission rate ,BLE5 You can achieve 20_{30KB/s;BLE4 Generally in 4}5KB/s.

Lenz technology has independently developed wireless RF and low-power Bluetooth BLE5.2 Chip and has global intellectual property rights , in the light of AIoT Internet of things and individual consumers , Provide Bluetooth master fully integrated chip 「 Commonality of software and hardware 」 Solutions and core devices , Supporting all-round APP Software platform customization development . The Bluetooth chip scheme is applied to intelligent wearable devices 、 Bluetooth indoor navigation 、 Smart home 、 Health care 、 Sports build body 、 The data transfer 、 Remote control 、 Personal peripherals and AIoT Internet of things and so on .
