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. 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. 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. - Home automation - Sensor networks - Building automation - Personal Area Networks - Health/fitness sensor and monitor devices - Medical devices - Key-fobs + wrist watches - Interactive entertainment devices - Remote controls - Gaming controllers - Beacons - A4WP wireless chargers - Computer peripherals - Mouse ## **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. ## **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 BLEprofiles, such as: - HID services - Medical services (BLS, HRS, HTP…) - Alert services (ANS, IAS, PASS …) - Information services (CTS, DIS, TPS …) - and others For full feature list see the nRF52832 documentation . - Keyboard - Multi-touch trackpad www.amber-wireless.com AMBER wireless GmbH, established in 1997, is a German electronics company.
