N command mode
After the module is electro-initialized, enter command mode, which only receives and responds to at+instructions.In this mode, the user can perform various control operations on the module through the at+instruction set.
Using at+instructions, you can move from command mode to transparent mode.

N transparent model
This mode is data transmission state, all input and output data (except escape characters) are transparent transmission processing, the module serves only as a data link between seria
