Bluetooth® low energy helps manage diabetes with insulin pen dosage tracking
我们的SmartBond™DA14531和DA14585 SoC提供了一些独特的功能，非常适合连接的健康产品，如注射器。亚博电竞菠菜例如，它们可以从氧化银电池和具有高内阻的超小容量电池操作，确保由于超低泄漏电流和检测第一剂量设置的能力，从休眠到活动模式时检测到第一剂量设置的能力，确保非常长的架子。
这些功能在Dnurse的“InsulinK”胰岛素剂量跟踪器中处于领先地位。这个支持蓝牙LE的剪辑将普通的胰岛素笔转换成连接的笔，以捕获注射和剂量信息的日志，并为更好、更有效的胰岛素消耗提供患者反馈。
冷链监测冷却解决方案
SmartBond微型™ DA14531 SoC是冷链监控的理想解决方案。它提供了最低的系统成本加上可扩展的无线电功率，以降低功耗低微瓦水平的超长电池寿命。Dialog提供了各种软件示例，例如，可以创建指示温度的智能标签或用于跟踪物流发光的最低成本测向标签。理想的应用包括疫苗运输和食品配送。亚博国际官网平台网址

接近和资产跟踪
Proximity applications are based on knowing and alerting you of the distance between two devices, such as keys or wallets, if the label goes out of range. Proximity information can also be used in asset tagging for inventory and automated access control or monitoring in cold chain tracking.

Bluetooth has played a key role in connecting computing and gaming peripherals since its introduction. It provides a simple and proven connectivity option for a host of new and emerging peripherals, while securing access to the most personal data.
As electronic equipment becomes smarter and more mobile, the way we interact with it is changing. We want more control, more convenience and less clutter, which is driving huge growth in the wireless HID market. Bluetooth low energy is per default supported in recent versions of windows, which truly enables the wireless desktop.

DA14585如果它在OTP标题上更改MAC地址
Posted by达斯达斯10分 1回复Greetings!
标题更加不言自明。我有a BLE Device with DA14585 on it. And the Mac-Address is burned into OTP header.
有没有办法绕过或忽略OTP Mac地址编程在SmartSnippet或任何其他方式？
Ideally, right now Im seeking a way to implement Random Mac-adress on these devices.
在目前的情况下，有没有办法做到这一点？

嗨Darthdas，
Thanks for your question online. Since the BD address is hardcoded in the OTP Header and so the Bluetooth Device Address filed is not empty, there are the following probable solutions :
1.使用SW中的硬编码BDA，但需要一些SDK修改。请检查系统init（）和第1253行 - otp_hdr_get_bd_address（）。此函数从OTP标头读取BDA地址。然后，NVDS_GET_FUNC（）将检查OTP中是否存在BD地址（case nvds_tag_bd_address）。如果是，则（dev_bdaddr不空白），则FW将使用存储在OTP中的BDA。否则，它将从NVDS（CFG_NVDS_TAG_BDDRESS）中获取BDA。因此，可能是可能的解决方案可以将DEV_BDADDR显式设置为0xFF（空白），因此FW将从NVDS（CFG_NVDS_TAG_BD_ADDRESS）中使用BD。
2. Use Static Random BDA that is generated from a unique number in OTP. In this case you should set the USER_CFG_ADDRESS_MODE macro to APP_CFG_ADDR_STATIC in the user_config.h header file and place the default_app_generate_unique_static_random_addr() API in .app_on_generate_static_random_addr callback in user_callback_config.h file.
3.在OTP头中使用公共BDA（在不同的位置）。同样，需要在otp\u hdr\u get\u bd\u address（）中进行一些修改，因为它从0x7F87FD4读取。你必须修改这个地址。
