为什么刷了冰人固件用这个gui读不出卡信息了？ about proxmark3gui

[wh201906]

你的固件和客户端匹配吗？如果匹配的话版本号是多少呢？

[Mabisi]

V0.2.5-win64-rrg_other-v4.14831

匹配，用的 rrg 14831这个版本

[wh201906]

要不先试一下v4.14434？目前我手上没有设备，等过几周我会去试一下v4.14831有什么问题

[Mabisi]

三个版本都试了，全都无法读取高频卡。。然后我又刷回以前买的软件的固件发现也不能读取了。。。啥情况大佬
低频的卡所有固件都正常。。搞不懂

[wh201906]

会不会是硬件有问题？在命令行下面跑hw tune看一下两个天线能正常工作吗

[Mabisi]

测试了是正常的😢

那么命令行读卡正常吗？

[wh201906]

你把卡片放到高频天线上，然后跑hw tune，看一下有没有压降？

[Mabisi]

有一点。。

基本没有压降看错了，有压降，但是很小
卡片和PM3高频天线对准了吗？也有可能是卡片本身有问题或者PM3硬件有问题

[Mabisi]

感谢大佬，那我在研究研究，固件刚入手的新的刚用了几次，换冰人固件之前都是正常的。。。

[wh201906]

我目前手上的硬件跑hw tune空载是28.3V，有卡的时候是26.5V。感觉还是你的硬件有问题，电压不应该只有十多伏的
这个issue我先关闭了，如果有进一步的发现你可以再打开
