ble5.0 master-slave integrated Bluetooth module B26 broke out at the first time, and was widely praised for its ultra-high cost performance and excellent performance once it was listed.
B26 Data Document:
Five functional features
Master and slave are one
HLK-B26 is a BLE5 developed and produced by Hi-Link Electronics0 master-slave integrated Bluetooth-serial port transparent transmission module, all kinds of devices with serial ports can simply and quickly use Bluetooth wireless transmission and receive data through this module.
At the same time, the B26 can be set up as a Bluetooth slave device or a host device to use, and the master mode supports the connection of 1 slave, and the slave mode supports the connection of up to 1 master.
Ultra-low power consumption
The HLK-B26 Bluetooth module consumes as little as microamps, has a sleep current of 102 A, and supports custom connectivity and broadcast intervals.
Power consumption (single state) Bluetooth tx current (0dB) 57mA, Bluetooth RX current 55mA, sleep average current 1023μa。
The micro-ampere-level power consumption coupled with the ultra-small size can well solve the power supply problems encountered in the perennial use of today's IoT Bluetooth devices, and a standard coin cell battery can be used for many years of the device.
ble5.0 Bluetooth
The HLK-B26 Bluetooth module supports BLE50. Fast transmission speed, high sensitivity, long propagation distance, wide application scenarios.
BLE Bluetooth 50 introduces technical improvements at the physical layer with a 2x rate increase, a 4x range increase, and an 8x increase in broadcast data capacity. It also introduces a low-power broadcast and connectivity mode, as well as a new 2Mbps high-speed data transfer mode.
The transmission distance is 40-60m
The transmitting power of the HLK-B26 Bluetooth module is adjustable, up to 8dBm, the receiving sensitivity can reach -92dBm, and the transmission distance is 40-60 meters in an open environment.
At the same time, the B26 mesh networking function is currently in the testing stage, and the transmission range will be greatly increased after the function is launched.
OTA Bluetooth wireless upgrade
The HLK-B26 Bluetooth module supports OTA Bluetooth wireless upgrade module firmware, wireless configuration module parameters, and can be tested by B40 test suite and B40 APP.
At the same time, the B26 has a fast network distribution speed, which can be quickly tested by Hilink's mobile phone Bluetooth transparent transmission test APP.
Application scenarios
Smart home appliances
HLK-B26 has the characteristics of low power consumption, low cost, and fast network distribution speed, and can be widely used in smart home appliances.
Through Bluetooth technology, it can be wirelessly connected and interacted with the mobile phone, so that ordinary smart home appliances can control smart sockets, smart lights, smart door locks, etc. through the mobile phone.
Instrumentation
The B26 is ideal for instrumentation due to its wireless transmission, stable transmission signal, low power consumption and high cost performance.
The integrated B26 instrumentation equipment can ignore the external environment when monitoring data, and read and monitor data stably and accurately.
Industrial and agricultural control
Smart devices in industry and agriculture are widely used, requiring energy saving, environmental protection and low cost, so the B26 is a low-cost and low-power Bluetooth module that is very suitable.
Through B26 Bluetooth wireless connection to various control or sensing intelligent industrial and agricultural equipment, reading and control, etc.
HLK-B26 has master-slave integration and BLE50 Bluetooth, cost-effective, ultra-low function, simple development, fast testing, etc., and a wide range of application scenarios.
