CC2640蓝牙建立连接困难

TI的工程师，本人使用CC2640不久，请帮忙解答一下。

我缩减了OAD targetImageA的空间留给ImageB（超过了40KB）来使用，ImageB空间变成从0x7000至0x13000，保持BLE stack空间不变，这样ImageB可以编译通过且可以烧录至Flash运行。但是我还是遇到一个问题，请帮忙分析一下，在用DeviceMonitor通过CC2650DK扫描到CC2640后连接很困难。下面是使用CC2650DK通过DeviceMonitor抓下的log，请帮助分析下是什么原因导致的建立连接困难？谢谢。

（1）大多数情况是连接直接中断，GAP Link Terminated: status=0 h=0 reason=0x3e

21:34:06.580 > AR502CG logger disconnected

21:34:07.108 > Connect request

21:34:07.219 > GAP Link Established: h=0 CI=0x0819 SL=0 TO=0x00b8

21:34:07.396 > Failed to establish

21:34:07.396 > AR502CG logger disconnected

（2）连接消耗时间很长，发现服务以及发现特征值好像很困难

21:34:09.810 > Connect request

（3）连接上了但是很快就断开GAP Link Terminated: status=0 h=0 reason=0x28

09:41:52.910 > Connect request

国内的TI FAE都很忙，还是我的问题没有说清楚，都没有人回答吗？

Mi,

请问，

硬件都是TI的开发板？还是你自己的板子？

默认TI的例程在同样的环境下就没问题了？

蓝牙的协议库函数比较大，通常cc2640的oad都用外部的flash,估计你删减了许多功能，因此工作不正常吧。
