change, or you won't be able to control the module. The instruction’s transfer speed will change
accordingly if changes the transfer speed of UART. The range of transfer speed of the instruction
is from 1.2Kbps – 115.2K bps.
2) LED Function Description:
The red and green LED will flash when there is power and the module is working.
The module will be ready for configuration mode if EN(ENABLE) pin is low(default is low)，
CON(Config) pin is low. When in configuration mode, the red and green LED will both be solidly lit.
The green and red LED will not be solidly lit if the module is not in configuration mode.
The red LED flash when the module is transmitting, the red LED will be off when the transmission
is finished.
The green LED is off when the module is waiting for data to be received, the green LED will flash
once when the module receives data.
