s110_nrf51_8.0.0 The main features of this release are the ability to set the size of the GATT Server Attribute Table when initializing the BLE stack, the possibility for the application to be notified when the SoftDevice receives scan requests, and the ability to disable RF channels for advertising. Changes to CPU availability during radio events, DC/DC converter configuration, and PPI channel allocations have been made to take advantage of the nRF51 series IC revision 3. The BLE API has been aligned to that of the S120 SoftDevice. Notes: This is a major release which has changed the Application Programmer Interface (API), requiring applications to be recompiled. This SoftDevice version is not Production tested on all IC revisions, and is not compatible with nRF51 IC revision 1. Users of the SoftDevice must verify the compatibility of their SoftDevice/IC combination for development and for production. Compatibility information is found in the nRF51 Series Compatibility Matrix, which can be downloaded from the Nordic Semiconductor web page. SoftDevice properties The SoftDevice Specification corresponding to this release is the S110 SoftDevice Specification v2.0. This version of the SoftDevice contains the Master Boot Record (MBR) version 1.0.1. The combined MBR and SoftDevice memory requirements for this version are as follows: Flash: 96 kB (0x18000 bytes). RAM: 8 kB (0x2000 bytes) (default value - dependent upon configured size of the GATT Server Attribute Table). New functionality SoftDevice The application can now configure the amount of memory reserved for the GATT Server Attribute Table when initializing the BLE stack (DRGN-3744). Configuration is optional. By default, the RAM reserved for the Attribute Table will be 0x700 bytes. This is the same default allocation as in the S110 v7.1.0. GAP The application can now configure the SoftDevice to deliver events when scan request packets are received (DRGN-2880, NRFFOETT-281). The application can now selectively disable RF channels used for advertising (DRGN-2598, NRFFOETT-179).

NRF51822新手笔记--自定义服务。基于SDK12开发的温湿度服务传输，可用于学习如何自定义蓝牙服务

NRF51802是可以完全兼容替代NRF51822的，都出自同一家公司。 为了支持更多的客户使用起来，NRF51822出了精简替代低成本的方案

该继电器控制家电设计基于nrf51822的开发板设计。分享一下这个开发板的综合例程，还配了一个apk程序。同时该开发板上有蜂鸣器，led，按键，继电器，dht11温度湿度传感器（兼容ds18b02），光敏电阻。程序一上电蜂鸣器叫一下，就代表正常。 视频演示: 先看板子样子: apk界面，通信协议在帮助那里。 实物购买链接:https://item.taobao.com/item.htm?id=42399651853&mt=
