HOW DOES IT WORK?
ANNA-B412 Click is based on the ANNA-B412, a standalone Bluetooth 5.1 low-energy module from u-blox. Under the metal hood, all the hard work is done by the nRF52833 from Nordic Semiconductor, which includes an integrated 2.4GHz transceiver with +8dBm output power and powerful Arm Cortex-M4 with FPU processor. In addition, it is equipped with 512KB of flash memory and 128KB of RAM. For a Bluetooth connection in a 2.4GHz frequency band, ANNA-B412 Click is equipped with a printed PCB antenna with support for 40 channels. The Bluetooth antenna has +9dBm of maximum radiated output power. For NFC, ANNA-B412 Click is equipped with a u.Fl connector, and can operate as a 13.56MHz NFC tag at a bit rate of 106Kbps.
One of the main features of this module is the Angle of Arrival (AoA) and Angle of Departure (AoD) with the support of a Bluetooth 5.1 Direction Finding service. These features can be used for indoor positioning, wayfinding, asset tracking, and more. To optimize power consumption, the module supports Active, Standby, and Sleep modes.
Two buttons (T1 and T2) can be used to control the system. By combining these buttons while operating or during Power-Up, you can restore settings to their default values, open a Bluetooth LE connection to a peripheral device, enter bootloader mode, or exit the bootloader mode and restore all settings to their factory default values. The onboard RGB LED notifies the system status signals, which can be idle in Data mode/Extended data mode, idle in Command mode, connecting, and connected. In addition, ANNA-B412 Click is equipped with ten u-connectXpress IO pins, separated into two headers, which can be used for user configurable purposes.
ANNA B412 Click uses a 4-Wire UART interface to communicate with the host MCU with a commonly used UART RX/TX and UART RTS/ CTS as UART control flow pins. In addition, the UART DTR data terminal ready and the UART DSR data set ready are also available. The default baud rate is 115200bps. The RST pin can be used to reset the module with active LOW. Besides the library we provide, you can use a set of AT commands to control the ANNA B-412 module over the UART interface.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
