如何使用EZ-Serial订购零件

我的产品使用CYBLY-222014-01与EZ系列V1.1.1，我想确保订购这些部件与正确的固件编程。我必须说明什么才能确定这一点？
我以前曾问过这个问题，并且被告知所有的零件都有这种情况，但是我不知道什么时候我的CM供应的零件是装运的。
是否有特定的第一日期代码或零件编号我可以要求？
我给的部件没有可识别的日期代码和错误的固件。

  My product uses CYBLE-222014-01 with EZ-Serial V1.1.1  I want to be sure of ordering these parts programmed with the correct firmware. What must I specify to be sure of getting this ?
I have previously asked this question, and been told that all parts after have this, but I have no way of knowing when the parts supplied by my CM were shipped.

Is there a particular first date code or part number I can request ?

The parts I have been given have no recognizable date code and the wrong firmware.
