wg7310 WIFI模块（WL1271芯片）链接ap不稳定

QUAN WU

Other Parts Discussed in Thread: DM3730

我用的佐臻DM3730 方案，它和WG7310 WIFI模块一起工作，我发现这个wifi模块链接AP不稳定，经常掉线，自己又连接上，而且链接上还出现错误，虽然还能工作，当不知道稳定性与这个有关系么，大家有了解的，给我指条明路把。

自己顶一下吧，我发现这个wifi信号强度变化特别大，我连接上一个AP，我的手持设备横着和竖着 wifi信号强度差别就很大，这怎么能改善了，wifi天线我就是在淘宝上买的天线，比较小的。3dbm 4dbm 5dbm 我都试过，但wifi信号都不是很稳定。

我看见代码ANDROID 2.3代码中有/**
     * Calculates the level of the signal. This should be used any time a signal
     * is being shown.
     *
     * @param rssi The power of the signal measured in RSSI.
     * @param numLevels The number of levels to consider in the calculated
     *            level.
     * @return A level of the signal, given in the range of 0 to numLevels-1
     *         (both inclusive).
     */
    public static int calculateSignalLevel(int rssi, int numLevels) {
        if (rssi <= MIN_RSSI) {
            return 0;
        } else if (rssi >= MAX_RSSI) {
            return numLevels - 1;
        } else {
            int partitionSize = (MAX_RSSI - MIN_RSSI) / (numLevels - 1);
            return (rssi - MIN_RSSI) / partitionSize;
        }
    }

这个代码能反应出信号强度，这个代码还用根据不wifi模块做合适的调节吗？设置 MAX_RSSI MIN_RSSI 吗？我感觉信号太不稳定了？

ＷG7310是这样的，它每次不是上电的时候，都要下载一个配置文件到自带的RAM里面去，这个配置文件佐臻是有更新的，估计也会提高AP的性能，你参考一下这篇文章：http://blog.csdn.net/code_style/article/details/43796515

hold li 你好，谢谢你的回复。我看了这个链接，我看件这个固件了，它是蓝牙的固件，这个固件我有，不知道有wifi的固件没有。佐臻的。

除了固件更新支持外，还有一些参数是需要配置的，你找到Wlan相关的注册表里面的一些参数，是需要你去调试的，WG7310这颗新批这个TI官方早期是有文档针对这一块的说明的。

我也用的这两个模块，linux(非Android)，用一段时间久断线，重新加载驱动没用，除非重启系统，内核原来是2.6.32，后来佐臻说2.6.32上有缺陷，费了半天劲升级到2.6.37，结果还是连接一段时间之后断线，甚至系统重启。

使用的驱动参考如下链接：

http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Build_Instructions

不知道你有没有这个解决这个问题？

我这个问题还没解决，我发现一般是驱动自动down造成的，但我就没看出来为什么无源无故DOWN。

我看LOG 有

binder: 2079: binder_alloc_buf, no vma
<6>[87415.617401] binder: 1186:1379 transaction failed 29201, size 1560-0

不之这个问题对这个影响多大，这个问题我也一直没有解决。

我QQ 31953894 你的告诉我，或者加我QQ也好，交流一下

最新的驱动版本是WiLink_Driver_6.1.0.1.149，不知道你是不是这个版本，自己修复了WG7310硬件出现故障时，系统开机会卡死的问题，目前AP很稳定，没有任何问题。

WG73的驱动是90%以上代码是跨平台的，只有platforms/os目录下的代码是平台相关的实现，包括各个平台的NDIS不同的实现，如果你的有问题，你好好看一下平台相关的代码部分，都是针对WL1271芯片

你好,

我用的是linux2.6.32和linux2.6.37(非Android)，硬件模块DM3730，wg7310-0A，不知道你是哪个系统?

你用的驱动能否给个链接？

还有你说的硬件问题和跨平台，我还不清楚是否与之相关，需要向你请教下！

0 Yukun Hao 8 年多前回复 QUAN WU

我现在2.6.37上得不到系统log，不知为何，所以只能跑程序观察断线时间和数据包量。我的QQ406943296，一块研究下这个问题。

驱动源码网上是找不到的，需要和Jorjin签订NDA，你才能拿到源码，不好意思。

非常感谢你的建议，我想问下你用的是原生linux还是Android，具体哪个版本？

我看到网上是可以下载WiLink_Driver_6.1.0.1.149，难道佐臻自己还进行优化了？

0 QUAN WU 8 年多前回复 Yukun Hao

你好，我使用的是佐臻的 3730模块（里面包括nand sram 的模块，bga封装），wifi模块也是SG7310-0A。WiLink_Driver_6.1.0.1.149在哪下载的，给个链接备被。

我用的是ANDROID 2.3.4系统（jorjin的提供的代码），不用LINUX系统

到这个芯片的官网看看吧，后者很多S3C6410板子使用这个芯片，你可以找一块的资料看看
