6.2.1 Data Mode
When the eS-WiFi module is interfaced serially, the serial interface needs to be
configured for 8-bit data, no parity, and one stop bit - (8-n-1) using the IWIN AT
Command firmware.
6.2.2 Flow Control
The eS-WiFi module and WICED do not require or support Flow Control, so Flow Control
should not be implemented.
6.2.3 Supported Baud Rates
The eS-WiFi module supports the following serial baud rates.
The AT Command ‘U2’ is used to set the baud rate.
Basic Rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800,
921600, 1152000, 1382400, 1612800, 1834200, 2073600, 2304000, 2764800,
3686400, 3916800
6.2.4 Default Serial Configuration
The eS-WiFi module is shipped with the default serial configuration of 115200 baud, 8 data
