DA14531 SDK

主要介绍了串口打印调试的方法、硬件错误查找定位以及堆日志Heap Log的显示。其中堆日志显示部分是官方于2022年2月17日新添加。教程图文并茂，几乎是手把手的方式来教会初学者。适用于 SDK 6.0.16（DA14585/6 和 DA14531）。DA14580已经被官方不建议在新产品中使用，开发者学习和使用SDK6是大势所趋。

1.面向未来，支持蓝牙5.1（核心规范） 2.仅需要一个 32MHz 晶振 3.使用1.5V电池时无需升压转换器 4.DA14531封装尺寸仅为2.0 x 1.7 mm

The DA14531 is an ultra-low power SoC integrating a 2.4 GHz transceiver and an Arm® Cortex-M0+ microcontroller with a RAM of 48 kB and a One-Time Programmable (OTP) memory of 32 kB. It can be used as a standalone application processor or as a data pump in hosted systems. The radio transceiver, the baseband processor, and the qualified Bluetooth® low energy stack is fully compliant with the Bluetooth® Low Energy 5.1 standard. The DA14531 has dedicated hardware for the Link Layer implementation of BLE and interface controllers for enhanced connectivity capabilities. The BLE 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 device is suitable for disposables, wireless sensor nodes, beacons, proximity tags and trackers, smart HID devices (stylus, keyboards, mice, and trackpads), toys, and medical and industrial applications.
