rfm12b和AVR
RFM12B and AVR
The RFM12B tranceiver module has become quite popular recently due
to its low price comparing to other modules on the market. But many
people nd it hard to make these tranceivers work (mainly because of buggy
programming guide provided by manufacturer, I guess...). This short article
contains compact and simple code that can be used just to get these modules
running for the rst time. It is based on manufacturer s examle code with
slight (but crucial) changes.

GPRS通信 源码
gPRS源码
2008-07-14
起初的硬件有鑫旺焊回来之后缺少几个电容和1个100k的电阻,电容主要是电源处储能的功能,
100k的电阻是sim300的sim卡上的simpress管脚和VEXT之间的,没焊接时虽能找到网络,但是会出现
掉网的情况,把这些补上后,没有问题了。所以以前的经验电路还是比较准确的。电源处一定要稳定。
另外这次初始化完成后就立即发短信,第一个短信没有成功。并且在串口接收中发短信等待模块返回信息时,
返回了call ready,之后再发就可以发出去了。这应该是模块还没有准备好。Call Ready
当搜寻到网络后开始发送短信,有时会出现+CMS ERROR: 517这个错误,应该是sim卡还未准备好,所以当搜寻到网络
后需要在多等待一会。待模块发出Call Ready信号后,再操作。

今天早晨在家准备调试一下这个模块发现始终找不到网络,用哪个卡都
