Enter AT command Mode
W7500S2E-R1 has two modes, AT command mode and data mode. In AT command mode, user
could use serial terminal or through user’s MCU main board to configure the parameters of the
module. Command enter will return a value (In echo mode, it will show the serial message). In
data mode, all the commands except the “+++” would be ignored to the module. Thus, entering
the “+++” command will change the module into AT command mode.
Note: ”+++” command rules: It needs to send “+” symbol continuously in 3 times to through
serial interface to the module. This command requires 1 second gap each before and after this
command has entered to activate the correct response from W7500S2E-R1. If not, it will
consider as user’s data input. This command does not require CRLF (Carriage-Return
Line-Feed)(\r\n). The factory default setting of the module is in AT command mode.
