Bluetooth BLE is a personal lan area network technology designed and sold by the Bluetooth Technology Alliance for emerging applications in healthcare, sports and fitness, beacons, security, home entertainment and other fields. Compared to classic Bluetooth, Bluetooth Low Energy is designed to maintain the same communication range while significantly reducing power consumption and cost.
Bluetooth low energy chips have the advantages of long transmission, low power consumption and low latency. In terms of transmission distance, classic Bluetooth is only 10-100 meters, and BLE can transmit up to 300 meters; in terms of connection, classic Bluetooth can only be transmitted through point-to-point mode, and BLE devices can be connected to other devices through point-to-point, broadcasting, mesh networking; the difference between the two is huge in power consumption, Bluetooth low energy operation and standby power consumption is extremely low, using a coin cell battery can work continuously for months or even years.
Lenz Technology launches the latest ST17H69 Bluetooth BLE5.2 chip
ST17H69 Bluetooth BLE5.2 chip is the latest 64-foot Bluetooth BLE chip from Lenz Technology, ARM Cortex-M0 32-bit processor, with 128KB-8MB system memory, Bluetooth protocol stack solidification, no longer occupy 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. Support LCD screen drive, with 24-bit ADC, can be used as blood pressure blood oxygen application, SIG compliant ad hoc networking application. 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, and the average current in low-power mode >40uA. The new Bluetooth receives a peak current of 4mA and transmits a peak current of 4.6mA, which is the power consumption of the MCU
