Under configuration (m0 = 1, m1 = 1), issue commands to the module serial port: C1 C1 C1, the module
returns the current configuration parameters, such as: c0 00 00 13 18 04.
Under configuration (M0 = 1, m1 = 1), issue commands to module serial port (HEX format): C3 C3 C3,
module returns current configuration parameters, such as: C3 02 80 10 09 01 00; 02 here 80 represents the
module model (E280 series), 10 represents version number, 0C represents module power, other
parameters represent other characteristics of modules.
Under configuration (M0 = 1, m1 = 1,) issue commands to the module serial port (HEX format): C4 C4
C4, module will generate a reset; during the reset, the module performs self-test, AUX output low, reset
After the AUX outputs high, the module starts working properly. At this point, mode switching or
initiation can be performed.
