TI中文支持网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
21:34:07.219 >AR502CG logger connected
21:34:07.228 > Service discovery started
21:34:07.395 >ReadByGrpTypeRsp: st=20 n=0
21:34:07.396 >GAP Link Terminated: status=0 h=0 reason=0x3e
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
21:34:09.923 >GAP Link Established: h=0 CI=0x0819 SL=0 TO=0x00b8

（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

大米：
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？
Albin Zhang：
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。
