NOTE: Generally the module in receiving state, if the IDLE pin continuously connect low level (>200millisecond), the module will be in sleep state, at the same time the module can not receive or transmit any data, only when the IDLE pin hang or in the state of high level (VH<3.5V), the module can be in receiving state again.
