使用移动APP-BLE或WIFI进行仪器控制的范围

你好，
我们正在开发一种新的仪器，它需要通过蓝牙或WiFi通信进行APP控制。
将没有路由器或网络来连接，因为用户可能是在外部或在工业环境中。
我们希望根据能力实现至少40米的范围。
我怀疑手机应用程序将是限制因素，但我感谢您的帮助，在最好的方式，以获得最大范围的应用程序控制的设备。
我不知道天气如何使用PCB芯片，并将外部增益天线连接到它，如果可以，我们可以使用BLE，因为我们已经开始在它周围设计。
任何重新设计的芯片将是伟大的，目前我们围绕CyBLY-222014-01设计，这是一个错误，因为它没有可能连接天线，但是，我们可以使用类似大小的东西等？会让我的生活更轻松。
谢谢

  Hi,

We are prototyping a new instrument which requires APP control via bluetooth or WIFI communication.

There will be no router or network to link up to as users will likely be either outside or in industrial environments.

We would like to achieve a range of atleast 40m depending on capabilities.

I suspect the phone APP will be the limiting factor but I appreciate your help in the best way to get maximum range for APP control of the device.

I don't know weather to use a pcb chip and connect an external gain antenna to it, and if so can we use BLE as we have already begun designing around it.

Any reccomended chips would be great to, currently we designed around the CYBLE-222014-01 which was a mistake as it doesnt have possibility to connect an antenna, however could we use something similar in size etc? would make my life easier.

thanks
