AT-09 Bluetooth 4.0 HM-10 CC2541 BLE Arduino Serial Port MLT-BT05


BT09 Bluetooth 4.0, master-slave integrated, straight-line pin, automatic connection, automatic search.
Ultra low standby power consumption 90uA~400uA.
Ultra-fast response speed 0.4 seconds,Android, iPhone, PC, MAC are all universal.
Send and receive no byte limit, up to 3K Bytes/sec.
No need to do MFI,support IOS system , support Android 4.3 system.


Designed for intelligent wireless data transmission, it adopts CC2541 chip of American TI Company, configures 256Kb space, and follows V4.0 BLE Bluetooth specification. Support AT command, users can flexibly change the serial port baud rate, device name, pairing password and other parameters as needed.


This module supports the UART interface and supports the SPP Bluetooth serial port protocol. It has the advantages of low cost, small size, low power consumption, high sensitivity of sending and receiving, etc. It can realize its powerful functions with only a few peripheral components.


Notes: Our master module can only be connected to our own slave module, which is generally used together. It is cannot connect to other slave devices. The slave module usage conditions: iPhone :4s and later models, system version iOS6 and later Android phone: The system version is 4.3 and later, and the Bluetooth version of the phone is 4.0.
