CoreBluetooth上的最大外围设备数量？ [英] Maximum number of peripherals on CoreBluetooth?

问题描述

我有兴趣在iOS上使用BLE接近传感器，一直在查找我的查询的一些答案，但找不到任何可靠的答案。

I am interested in working with BLE proximity sensor on iOS and have been looking up for a few answers to my query but could not find any solid ones.

1）CoreBluetooth可以处理的最大BLE从站数量是多少？

1) Is there a maximum number of BLE slaves the CoreBluetooth can handle?

2）奴隶（大约10个设备）是否能够一次全部操作，即如果有任何奴隶要断开连接，主人会在不影响他人的情况下被提醒？

2) Will the slaves (about 10 devices) be able to be operated all at once i.e. if any slaves were to disconnect, master will be alerted while not affecting others?

推荐答案

从理论上讲，可以连接到单个iOS设备的蓝牙LE设备数量没有限制（如果iOS设备充当中央设备，LE设备充当外围设备。）

Theoretically, there is no limit to the number of Bluetooth LE devices that can be connected to a single iOS device (if the iOS device is acting as central and the LE devices as peripherals).

然而，实际上，限制似乎是在同时连接到iOS的20个LE设备之上主。这个数字来自我所谈过的蓝牙LE发射器制造商和配件开发商。确切的数字可能会根据所涉及的特定iOS设备和蓝牙LE配件的传输属性而有所不同。

In practice, however, the limit seems to be somewhere above 20 LE devices being connected simultaneously to the iOS master. That number comes from both Bluetooth LE transmitter manufacturers and accessory developers that I've talked to. The exact figure will probably vary based on the particular iOS device involved and the transmitting properties of the Bluetooth LE accessories.
