Overview
Description
Module available: DA14695MOD
The SmartBond™ DA1469x family of Bluetooth® Low Energy solutions is a feature-rich range of multi-core microcontroller units for wireless connectivity.
The product family builds off the successes of Renesas' SmartBond line, boasting three additional cores that offer greater processing power, resources, range, and battery life, enabling developers to push the boundaries of a wide array of connected consumer applications. The DA1469x line provides developers with advanced connectivity features to future-proof their devices and fit the needs of multiple applications. Based on the Arm® Cortex®-M33 processor, DA1469x products offer developers greater processing power for intensive applications like high-end fitness trackers, advanced smart home devices and virtual reality game controllers.
Additionally, these wireless MCUs have a configurable MAC which enables manufacturers to deploy proprietary 2.4GHz and the latest Bluetooth Low Energy 5.2 protocol, opening up possibilities such as accurate positioning for Real-Time Location Systems (RTLS) and low latency communication exchange for applications like gaming. And, to enhance its sensing functionality, the line features a Sensor Node Controller (SNC) that runs autonomously and independently processes data from sensors connected to its interfaces.
Finally, the DA1469x family features a state-of-the-art Power Management Unit that utilizes best-in-class power management by controlling the different processing cores and only activating them as needed, while also eliminating the need for a separate PMIC and reducing the overall system size.

DA14695 - [BLE] - libble_stack_da1469x.a - float-abi: hard vs. soft(p)
Hello together, I am experiencing a difficulty regarding the SDK provided `libble_stack_da1469x.a` and its integrated FP option. I have another external library (closed source), which is only available with soft-float-abi. Unfortunately, the SDK only ships with this one single `libble_stack_da1469x.a`, which is ...
