1、SF32LB58平台，现阶段基于watch例程，想新增一个蓝牙主设备的程序，主动连接从设备并且能正常通信。
现在遇到的问题是，基于附件的代码，现在新增的程序能正常的连接从设备，但是接收不到从设备的数据，帮忙看看哪里出现问题。
simple_ble_master.c (9.0 KB)
只是看附件代码没看出什么，方便将整个工程进行上传，并告知操作流程以及预期现象和实际现象吗
工程太大了，发送不了，现在就是串口发送数据，然后启动下面simple_ble_start(void)这个函数。
因为原例程是作为从设备被手机连接。现在想法是新增一个任务，设备同时作为从设备跟主设备，作为主设备可以连接其他从设备，并且能跟从设备进行通信。现阶段遇到的问题是：启动之后，连接成功了，但是不能通信。连接打印的数据如下：从设备一直在发送数据，主设备没有接收并且打印。

- sibles_register_remote_svc的callback，不能传null，对面的notification或者indication是从这里传回来的（SIBLES_REMOTE_EVENT_IND）。
- 需要先在client characteristic configuration descriptor（cccd）打开notification或者indication，才能收到对端发过来的notification或indication。
- 以上两点都可以参考central_and_peripheral工程的main.c以及bf0_sibles_ancs.c，都有查找注册server端服务的代码流程
好的，我已经调试好了，感谢
