BL-4011, Bluetooth low energy (BLE) single mode module is targeted for low power sensors and 

accessories. It offers GATT profile as the based lower profile. We could also provide other standard BLE 

profiles such as proximity, find me … etc. The module provides flexible hardware interfaces to connect 

sensors, simple user interfaces – AT commands. 

 

The single mode radio enables it to connect to the dual mode Bluetooth products already in the market, as 

well as other Bluetooth low energy devices/ sensors. It can be used in equipments like a heart rate sensors, 

pedometers, watches, blood pressure meters, weight scales, households sensors, collector devices, 

security tags, wireless keys, proximity sensors, HID keyboards and mice. 

 

It can be powered directly with 1.8V ~ 3.6V power source, such as a standard 3V coin cell battery. 

BL-4011 only consumes a little energy in different sleep mode, for example 780nA in lowest power sleep 

mode. 

 

AtechOEM provides a proprietary GATT-based profile to our customers. The profile is similar to the 

classic SPP (Serial Port Profile) described in Bluetooth v2.1. Customers could use this special profile to 

transfer raw data between GATT-based connection in their application. AtechOEM also offer customized 

firmware services to meet specific applications more tightly.
