用个8位单片机+sim900a+gps模块自制建议定位装置

下面是程序代码复制粘帖过去IDE中，编译好后下载到arduino中就好了。

/* This sample code demonstrates the normal use of a TinyGPS object.

It requires the use of SoftwareSerial, and assumes that you have a

it won't plug in directly as with the beaglebone. just connect ground, rx and tx between the pocketbeagle and the adapter (making sure to cross rx to tx).。 and the last 3 bits could be selected by setting the appropriate address at pins a0, a1 and a2 on the serial eeprom. therefore by using these 3 bits we could attach up to 8 microchip 24aa128 serial eeprom on the same i2c bus。set antenna configuration (tx_ant, rx_ant) on the device. parameters are bitmaps of allowed antennas to use for tx/rx. drivers may reject tx/rx mask combinations they cannot support by returning -einval (also see nl80211.h nl80211_attr_wiphy_antenna_tx).。

短信群发到达率就是指真实的到达数量和企业提交的手机号相除，排除一些不良短信群发公司人为“扣量”的情况，短信群发到达率受发送号码的质量（包含空号、关机号码）、发送内容、网关质量等因素的影响，这也是为什么短信群发的达到率不可能的原因。短信内容：发送您的qq号码到对应的接入号解除限制(发送短信，腾讯公司不收取任何费用，由当地运营商收取一条普通短信费用)，稍后将手机关机5~10分钟就可以正常登录了。8.发送“ 学习 ”信号：用手机发送如下格式的数据到短信转发器，“ 学习 ”单片机gps模块有什么用，短信转发器收到后将会转发接收机学习信号单片机gps模块有什么用，并且其会向被捆绑的手机号发送“学习信号发送成功”的信息。
