我使用的是AndroidGoogle 附近的连接API 但我得到了非常高的延迟和低的吞吐量，即使是在使用 P2P_POINT_TO_POINT 或 P2P_STAR. 我高度怀疑，连接停留在蓝牙上，而不是升级到wifi（两个测试设备连接到同一个wifi路由器） . 我也确保了多播的权限，甚至尝试手动获取多播锁定 (https:/stackoverflow.coma13223018。).
请注意，我有一个奇怪的设置，一个设备是在Android 10 (S10e)，另一个仍然在Android 5.1 Lollipop。
在发送字节有效载荷时，我也得到了这样的错误。两台设备都会发生，但在老设备上发生的频率更高。

我还能做什么吗，还是我只能咬紧牙关买一台新设备？
