我发现向服务器发送信标数据并将其存储在数据库中有问题。它接收4个信标数据到数据库中（在sql语句中一次一个数据）。在这里，一段数据是beacon.getbluetoothname和beacon.getrssi以及beacon.getdistance的捆绑包。我用的是安卓信标库。
我最初的目的是更快地向服务器发送信标数据。我的主要问题是向数据库发送重复数据。我想从四个信标均匀地发送数据。如果将数据放入sndmsg（）中，它将发送到服务器。服务器是eclipse服务器，数据库是mysql
我知道冗余数据来自于传输速度慢。我想提高速度。是图书馆的极限还是灯塔的极限（冥王星的）有什么办法可以解决这个问题吗？
