工程支持4个设备连接，2个主机和2个从机。CC2642做主机连接了一个设备的情况下，两个手机交替去连接CC2642，重复多次之后，发现调用GATT_Notification接口发数据给手机时，无法发送数据返回0x16，重试多次也一样（每秒重发1次，超过1分钟没恢复）。连接间隔30ms，苹果和安卓手机都有此问题。
SDK：simplelink_cc13x2_26x2_sdk_5_10_00_48
手机型号：苹果13、华为P30 PRO
Nick Sun：
您好，
0x16是blepending，常意味着 BLE-Stack 正忙于执行一些其他过程。您可以提供发生这种情况时候的sniffer log吗？
是否可能是内存问题？我们建议不要使用通知。只需读取和写入数据到从设备即可。
,
RenLI Wang：
并不是内存问题，MAX_NUM_PDU由100改为250、用户任务的堆栈由10k改为20k，现象一样。出现这个问题之后，不断开连接是不能恢复的，不管等多久。出现这个问题之后，做主机调用GATT_WriteNoRsp给从机发数据时也是返回0x16
内存还是足够的

Nick Sun：
您好，
当 GATT_Notification（） 返回 0x16 （blePending） 时，表示 GATT 操作无法发生，通常是因为 GATT 操作的队列已满。队列可能已满，因为与排队速度相比，GATT 操作的执行速度不够快（请参阅 https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/1197903/launchxl-cc26x2r1-notification-returning-0x16）。
在您的情况下，由于 CC2642R 形成 4 个连接（其中 2 个是外设连接），并且由于问题很少重现，因此问题可能是由连接时间引起的。换句话说，在某些情况下，连接操作可能会重叠，并且必须删除某些操作。因此，连接清空 GATT 队列的机会较少，您最终会得到您遇上的行为。为了确定这是否是根本原因，您可以启用 RF observable （或使用Bluetooth sniffer）以查看在某些情况下是否丢弃了某些 RF 操作。
如果我描述的根本原因是您问题的实际根本原因，恐怕最好的解决方法是在检测到问题时关闭连接（即每当函数GATT_Notification 0x16连续返回几次时）并稍后重新建立连接。
我希望这会有所帮助。

您好，
出现这个问题时，并没有同时连接4个设备。做主机模式连接了一个设备。做从机模式，两台手机是交互去连接，不是同时连接两台手机，也就是同时只会连接2个设备，您说“删除某些操作”、“清空 GATT 队列”，这个是否有相关的接口可以去操作，比如出现问题时主动去清除
,
RenLI Wang：
还有就是，队列MAX_NUM_PDU目前已经增加到250,了，并且两个设备发送数据的频率都是秒级别的，所以队列满的可能性不大

您好，
RenLI Wang 说：您说“删除某些操作”、“清空 GATT 队列”，这个是否有相关的接口可以去操作，比如出现问题时主动去清除
如果要执行此类操作，则必须终止连接。
RenLI Wang 说：还有就是，队列MAX_NUM_PDU目前已经增加到250,了，并且两个设备发送数据的频率都是秒级别的，所以队列满的可能性不大
您是否验证了MAX_NUM_PDU值，是否设置正确？此外，您可能需要检查MAX_PDU_SIZE是否设置为与系统要求匹配的值。请注意，MAX_NUM_PDU 和 MAX_PDU_SIZE 都是使用 SysConfig 设置的。
