求助: CC2540 是否支持同时(分时也可以) 扮演多个角色 Broadcaster & Observer & Peripheral ?

–Broadcaster –an advertiser that is non-connectable
–Observer –scans for advertisements, but cannot initiate connections.
–Peripheral –an advertiser that is connectable and can operate as a slave in a single link layer connection.
–Central –scans for advertisements and initiates connections; operates as a master in a single or multiple link layer connections.

这多个角色是否可以同时（分时）使用，比喻 1s为 Broadcaster , 1s 为 Observer ，再1s为Peripheral ?

The BLE specification allows for a few different possible multiple-role configurations:
–Peripheral and Broadcaster –device operates as a slave in a single link layer connection, but meanwhile also can send out non-connectable advertisements (supported in Beta stack)
–Peripheral and Observer –device operates as a slave in a single link layer connection, but meanwhile also can scan for advertisements without initiating a connection (not supported in Beta stack)
–Central and Broadcaster –device scans for advertisements and initiates connections as a master, but also can broadcast non-connectable advertisements (not supported in Beta stack)

不能同时支持 Broadcaster 和 Observer ，那分时可以吧？
我们现在打算分时处理，先Broadcaster 1s，然后 Observer 1s ，但发现如下问题：
1、只有在第一次 Broadcaster 时，手机能找到 此 BLE设备 ，以后一直找不到
2、第一次切换到 Observer ，找不到我另外一台 Broadcaster 设备(实验时一直有一台BLE 充当 Broadcaster)
3、在Observer 1s 后切换回 Broadcaster 时，手机无法再找到此设备，此后无论怎么切换都再也不能被找不到了，只在第一次能被找到
4、在 Broadcaster 1s后切换回 Observer时，可以找到另外一台实验用的Broadcaster设备，以后切换也可一直找到，只在第一次时不能找到Broadcaster

代码是这样处理的：
创建 Observer Task 和 Broadcaster ，但都不启动，
1、启动Broadcaster 如下:
a、设置参数:GAPROLE_ADVERT_OFF_TIME & GAPROLE_SCAN_RSP_DATA & GAPROLE_ADVERT_DATA & GAPROLE_ADV_EVENT_TYPE & TGAP_LIM_DISC_ADV_INT_MIN ...
b、设置角色 : GAPRole_StartDevice
c、启动 Broadcaster GAPROLE_ADVERT_ENABLED
d、启动 1s 定时器，用以切换角色
2、Broadcaster 启动 1s 后，定时切换角色，关闭Broadcaster ，启动 Observer ，具体过程如下:
a、关闭定时器,停止Broadcaster : GAPROLE_ADVERT_ENABLED
b、启动 Observer( 设置 GAPOBSERVERROLE_MAX_SCAN_RES & TGAP_GEN_DISC_SCAN & TGAP_LIM_DISC_SCAN , 启动角色 GAPObserverRole_StartDevice , 启动 Observer : GAPObserverRole_StartDiscovery )
c、启动定 1s 定时器，用以切换角色。

3、Observer 启动1s后，定时器启动，进行切换 Broadcaster
a、关闭 Observer ( GAPObserverRole_CancelDiscovery ) ,进入 步骤 1
