WORKING MODE

1. STANDARD MODE

Standard mode is also called transparent mode in which the module receives from or sends

data to the host through serial port (UART) at preset data format and users don’t need to care

about the process of data inside the module. In this mode the EN pin should be set to logic

low in case the module will enter into deep sleep. SET pin doesn’t function in this mode so

users can set it to logic high.
