如何设计外部遥控器以使用BLE控制Android应用程序

本主题主要是开发一个Android应用程序，使用PSoC4BLE作为远程控制器。我想知道如何用一个外部遥控器控制一个Android设备（比如 手机）。我想要的功能，如D-垫，进入，返回，家庭等。我可以发送接收数据从我的BLE服务。然后，在接收到命令时，一些函数应该像输入或删除一样，或者通过D- PAD或TAB导航应用程序。
如果有类似的经历，请欣赏。

This topic is mostly about developing an android applica tion to use PSoC4 BLE as a remote controller. I want to know how to control an android device (like a mobile phone) with an external remote controller. I want functions like D-pad, Enter, Return, Home, etc. I can send an receive data from my BLE service. Then upon receiving a command, some functions should trig like Enter or delete, or navigate through an app by D-Pad or Tab.
Appreciate if anyone who had a same experience like this.
