java - 一个手机最多能 "检测" 到多少个蓝牙列表？

Question

1：能检测到就行，只用出现在我的列表里，不需要连接。

Answer 1

There should be no limit to this. After the bottom layer scans the SSID of the Bluetooth device, it will broadcast it, so there is no limit.

Answer 2

There is no limit to searching for nearby peripherals, but you can only connect 7.

Answer 3

There should be no limit, I tried 5 without any problem

Answer 4

No limit, depends on the timeout you set for the search.
