Low Power node must establish "friendship" with another node that supports the Friend Feature to reduce duty cycle of its receiver, thus power consumption of Low Power node can be reduced. Low Power node needs to find a Friend node to establish a friendship with it. The process involved is called "friendship establishment". Cooperation between Low Power node and Friend nodes enables Low Power node to schedule the use of the radio, thus Low Power node can receive messages at an appropriate or lower frequency without the need of keeping listening.

@@ -95,7 +95,7 @@ Selecting JTAG Adapter
 
 If you decide to use separate JTAG adapter, look for one that is compatible with both the voltage levels on the {IDF_TARGET_NAME} as well as with the OpenOCD software. The JTAG port on the {IDF_TARGET_NAME} is an industry-standard JTAG port which lacks (and does not need) the TRST pin. The JTAG I/O pins all are powered from the VDD_3P3_RTC pin (which normally would be powered by a 3.3 V rail) so the JTAG adapter needs to be able to work with JTAG pins in that voltage range.
 
-On the software side, OpenOCD supports a fair amount of JTAG adapters. See http://openocd.org/doc/html/Debug-Adapter-Hardware.html for an (unfortunately slightly incomplete) list of the adapters OpenOCD works with. This page lists SWD-compatible adapters as well; take note that the {IDF_TARGET_NAME} does not support SWD. JTAG adapters that are hardcoded to a specific product line, e.g. ST-LINK debugging adapters for STM32 families, will not work.

 The minimal signalling to get a working JTAG connection are TDI, TDO, TCK, TMS and GND. Some JTAG debuggers also need a connection from the {IDF_TARGET_NAME} power line to a line called e.g. Vtar to set the working voltage. SRST can optionally be connected to the CH_PD of the {IDF_TARGET_NAME}, although for now, support in OpenOCD for that line is pretty minimal.

     - IV 更新程序用于更新 ESP-BLE-MESH 网络的 IV Index 的值，这个值和消息加密时所需的随机数相关。为了保证随机数的值不重复，所以将这个值定期增加。IV Index 是一个 32 位的值，是一种共享网络资源，比如一个 mesh 网中的所有节点共享一个 IV Index 值。IV Index 从 0x00000000 开始，在 IV 更新过程中递增，并由特定的进程维护，以保证整个 Mesh 网内共享一个 IV Index。当节点认为它有耗尽其序列号的风险，或它确定另一个节点即将耗尽其序列号时，可以启动该程序。注意：每次的更新时间不得低于 96 小时。节点接收到 secure network beacon 或者确定自己的序列号大于特定值时，会触发 IV 更新程序。

 如果您想使用单独的 JTAG 适配器，请确保其与 {IDF_TARGET_NAME} 的电平电压和 OpenOCD 软件都兼容。{IDF_TARGET_NAME} 使用的是业界标准的 JTAG 接口，它未使用（实际上也并不需要）TRST 信号脚。JTAG 使用的 IO 管脚由 VDD_3P3_RTC 电源管脚供电（通常连接到外部 3.3 V 的电源轨），因此 JTAG 硬件适配器的管脚需要能够在该电压范围内正常工作。
 
-在软件方面，OpenOCD 支持相当多数量的 JTAG 适配器，请参阅 `OpenOCD 支持的适配器列表 <http://openocd.org/doc/html/Debug-Adapter-Hardware.html>`_ （请注意这一列表并不完整），其中还列出了兼容 SWD 接口的适配器，但请注意，{IDF_TARGET_NAME} 目前并不支持 SWD。此外，硬编码为只支持特定产品线的 JTAG 适配器也无法在 {IDF_TARGET_NAME} 上工作，例如仅针对 STM32 系列产品的 ST-LINK 适配器。

 保证 JTAG 正常工作需要连接的信号线包括：TDI、TDO、TCK、TMS 和 GND。一些 JTAG 适配器还需要 {IDF_TARGET_NAME} 提供一路电源到适配器的某个管脚上（比如 Vtar），用于设置适配器的工作电压。您也可以选择将 SRST 信号线连接到 {IDF_TARGET_NAME} 的 CH_PD 管脚上，但请注意，目前 OpenOCD 对该信号线提供的支持相当有限。
