Bluetooth Smart

The Bluetooth® Smart (previously called Bluetooth Low Energy) technology is a part of the Bluetooth Core Specification from Bluetooth v4.0 onwards. Bluetooth Smart brings Bluetooth wireless connectivity to low cost, small battery operated devices that require months or even years of battery lifetime.
 
Bluetooth Smart will therefore enable a new and extended range of applications to benefit from Bluetooth wireless technology including watches, proximity tags, sports and fitness sensors, healthcare sensors and remote controls.

Key features of Bluetooth Smart include:

    Ultra-low peak, average and idle mode power consumption
    Ability to run for years on standard coin-cell batteries
    Low cost
    Multi-vendor interoperability
    Enhanced range
 
Bluetooth Smart has official support in iOS and Android mobile platforms as well as most desktop platforms including OSX, Windows 8 or higher and Linux.

Product Description

The AMB2621 is an ultra-low power 2.4 GHz wireless module integrating the nRF52832 System on Chip including a 2.4 GHz transceiver and an ARM Cortex®-M4F CPU with flash memory. The module is optimized for applications where costs and low-power optimization really matter.
 
Several pins with alternate functions are available to e.g. connect LEDs, or realize an SPI, I2C, ADC or handshake for the UART as well as NFC (near field communication).
 
In delivery state the module comes with an AMBER firmware according to option 1.


Option 1: AMBER Firmware

By default, the module provides the industry proven, fully qualified Bluetooth® Smart (previously called Bluetooth low energy) stack from Nordic, plus the AMBER firmware. The latter contains a SPP-like profile, which offers a fast secured data transmission of small packets with up to 128 bytes payload. Furthermore the AMB2621 includes an easy-to-use command interface allowing a convenient configuration and operation.
 
The module can perform both, an advertising state in order to be found, or a scan for finding other devices, which are advertising. Data transmission can be executed as soon as a (secured) connection has been set up.
 
In addition data can be broadcasted quickly using so called Beacons. The module enables distance estimation (localization) using RSSI and output power in just one advertise packet for optimized power consumption.
 
As interface to the host system a 2-wire UART interface is provided with a default data rate of 115200 Baud. OTA firmware update via PC or Android / iOS App is supported. An Android App supporting the SPP-like operation is also available on request.

The AMB2621 firmware (version 3.0.0 or newer) provides the “peripheral only” operation mode, that allows the easy adaption of already existing custom hardware with the BLE interface. By default, this mode offers the static passkey pairing method and a transparent UART interface. With this, custom hardware can be accessed by mobile BLE devices (like smart phones including a custom App) using an authenticated and encrypted BLE link without the need of configuring the module.

Option 2: Custom Development

Based on the Nordic Semiconductor SDK and demo examples various BLE-profiles and custom applications can be realized and flashed on the AMB2621 module. The versatile and well documented Nordic stack ensures quick and easy realization of various standard BLE-profiles, such as:
 
HID services
Medical services (BLS, HRS, HTP…)
Alert services (ANS, IAS, PASS …)
Information services (CTS, DIS, TPS …)
and others
