我们可以将android智能手机蓝牙角色更改为奴隶吗 [英] Can we change android smartphone bluetooth role to slave

问题描述

默认情况下，所有智能手机都运行蓝牙主模式，因此它们可以连接到多个设备.对于我的项目，我需要将android智能手机的蓝牙角色更改为"Slave".这是必需的，以便另一个主机(智能手机)可以连接到它.问题是我们可以将手机上的BT角色从主机更改为从机吗?可以通过应用程序完成此更改，还是将固件/ROM级别更改为是否进行过任何类似的实施.

By default all smartphones operate Bluetooth master mode so they can connect to several devices. For my project, I have a requirement to change Bluetooth role of the android smartphone to "Slave". This is needed so another master (Smartphone) could connect to it. The question is Can we change the BT role on a phone from master to slave? Can this change be done by an app or would this be a firmware / ROM level change Has any similar implementation been done.

推荐答案

是的，您可以将Android设备设置为从设备，可以使用

Yes you can set your Android device to be a slave, you can use the nRF Connect app for this. As soon as you launch the app, you'll have three tabs at the top, namely Scanner, Bonded, and Advertiser. Simply select Advertiser and add your Display name as well as Advertising Record if you want to.

我希望这会有所帮助.
