有没有GPRS在在线状态又能低功耗的GPRS模块
就像MC55的 CFUN=7一样CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled while CTS is active. If char-acters are recognized on the serial interface, the ME stays active for 2 seconds after the last character was sent or received. ME exits SLEEP mode only, if AT+CFUN=1 is entered. gprs在线，只要不发数据，一样功耗很小。就是发数据的时候大。
