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 CortexTM-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.
By default the AMB2621 contains the AMBER firmware
according to option 1. Upon request the customer’s own
firmware (option 2) may be flashed during production.
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 an SPP-like profile, which offers a fast
secured data transmission of 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
mode 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 a second option the module can be switched into
peripheral only mode with transparent UART and static
passkey pairing.
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.
Option 2: Custom development
Based on the free 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
