Has anyone researched how to access the gps chipset on a blackberry over usb so that it is unnecessary to transmit this data over the cell carrier's data network?
有没有人研究如何通过usb访问黑莓上的gps芯片组,以便不必通过蜂窝运营商的数据网络传输这些数据?
Is it possible to access the GPS chipset, store information in a buffer, and open an interface connection (over the usb charging port), for access? Not sure if J2ME allows for this...
是否可以访问GPS芯片组,将信息存储在缓冲区中,并打开接口连接(通过USB充电端口),以便访问?不确定J2ME是否允许这样做......
