连接稳定性问题

嗨对话框，

我正在开发一对BLE设备，两个服务器和从站，基于DA14580。在彼此连接之后，即使我留下这些处理器闲置（没有读/写/通知，否I2C，GPIO ...处于活动状态），但它们仍然断开随机连接。它看起来像链接层中的一个腐败，因为在断开连接后，它们无法再次重新连接。以下是我为此连接设置的参数以及一些Wireshark捕获。

msg-> nb_peers = 1;
memcpy（（void *）和msg->对等体[0] .addr，（void *）peer_addr，bd_addr_len）;
msg->对等体[0] .addr_type = peer_addr_type;
msg->con_intv_max = 10;
msg-> con_intv_min = 10;
msg->ce_len_max = 0x20;
msg->ce_len_min = 0x20;
msg->con_latency = 0;
msg-> superv_to = 100;
msg-> scan_interval = 0x180;
msg-> scan_window = 0x160;
msg-> op.code = gapm_connection_direct;

Server and client keep the connection for 60s and could not connect to each other anymore.

我仍然可以看到奴隶侧广告，但甚至使用iPhone使用LightBlue应用程序，我无法再连接到奴隶。

在此测试中，我将连接间隔设置为12.5 ms。在这种情况下，服务器和客户端将在60秒到45分钟后随机断开连接。

在后一种测试中，我将连接间隔更改为30ms。他们可以保持连接更长（超过10小时），但仍然脱离了。

我想假设我在空闲状态下将处理器留下，一切都应该自动通过BLE堆栈处理并发送空以保持连接应与我的应用程序代码无关。此外，我在断开连接时没有任何应用活动。

请帮我找到断开连接和如何提高连接稳定性的原因。

非常感谢。
