DA14581 Block Diagram

説明

The DA14581 integrated circuit is an optimized version of the DA14580, offering a reduced boot time and supporting up to 8 connections. It has a fully integrated radio transceiver and baseband processor for Bluetooth^® Low Energy. It can be used as a standalone application processor or as a data pump in hosted systems.

The DA14581 supports a flexible memory architecture for storing Bluetooth profiles and custom application code, which can be updated Over-the-Air (OTA). The qualified Bluetooth Low Energy protocol stack and the HCI-ready software are stored in a dedicated Read-Only Memory (ROM). All software runs on the Arm^® Cortex^®-M0 processor via a simple scheduler.

The Bluetooth Low Energy firmware includes the L2CAP service layer protocols, Security Manager (SM), Attribute Protocol (ATT), the Generic Attribute Profile (GATT), and the Generic Access Profile (GAP). All profiles published by the Bluetooth SIG as well as custom profiles are supported. The transceiver interfaces directly to the antenna and is fully compliant with the Bluetooth 4.2 standard.

The DA14581 has dedicated hardware for the Link Layer implementation of Bluetooth Low Energy and interface controllers for enhanced connectivity capabilities.

AN-B-007 DA1458x Bluetooth Direct Test Mode
PDF 683 KB 2019年10月24日
AI生成コンテンツ: The DA1458x Bluetooth Direct Test Mode enables RF PHY testing through a UART interface with Bluetooth testers, supporting continuous Tx output, Rx testing, and packet error rate measurements. Setup involves configuring UART baud rates and using various testers such as R&S CBT, Anritsu MT8852B, and LitePoint IQ2010/2015. Production tests can be run via GUI tools like Connection Manager or CLI tools like prodtest.exe. The document details hardware connections, software setup, and test procedures for efficient Bluetooth RF testing.

AN-B-010 DA14580 using SUOTA (Software Update Over The Air)
PDF 769 KB 2019年8月16日
AI生成コンテンツ: Software Update Over The Air (SUOTA) enables wireless firmware updates on DA1458X devices via Bluetooth Smart. It uses Dialog’s proprietary SPOTA service, implemented as a GATT Primary Service with two roles: SPOTA Initiator (client) and SPOTA Receiver (server). The update requires external non-volatile memory like SPI flash or I2C EEPROM. The DA1458x SDK supports both Central and Peripheral roles for SUOTA, facilitating seamless over-the-air software updates from iOS and Android platforms using Dialog SmartSnippets.

AN-B-051 SmartSnippets Power Profiler Calibration
PDF 455 KB 2019年5月06日
AI生成コンテンツ: SmartSnippets Power Profiler requires calibration to improve power measurement accuracy for DA14580 Pro and Expert development kits. Calibration adjusts offset currents and multiplication factors to compensate for hardware variations in each kit. The process involves preparing the development kit by isolating power-consuming modules, configuring jumpers, and using a digital multimeter to measure current through specific pins. Calibration steps differ slightly between Pro and Expert kits but aim to provide precise energy consumption estimates for applications.

AN-B-029 : Tutorial - Developing a custom profile on DA1458x
PDF 1.17 MB 2019年4月03日
AI生成コンテンツ: Custom Bluetooth profiles can be implemented on the DA14580 by building on the sample128 service. This involves creating a project using the template_fh sample application, integrating the sample128 service source code, and configuring the project accordingly. The process includes creating and enabling the service database, implementing message handlers, and testing functionality. Modifications such as changing characteristic data sizes and adding new characteristics with GATT notify support are also covered. The guide assumes familiarity with Bluetooth Smart concepts, peripheral device roles, and the Keil µVision MDK IDE.
