Library Description
Library carries generic command parser adopted for AT command based modules. Generic parser.
Key functions:
wifible_cmdSingle - Sends provided command to the module.wifible_setHandler - Handler assignation to the provied command.wifible_modulePower - Turn on module.Examples description
The application is composed of the three sections :
Commands : '+' - Next command 's' - Start command 'e' - change example (WiFi example / BLE example)
Additional Functions :
Timer initialization and default handler.
Note:
void applicationTask()
{
uint8_t dataReady_;
char receivedData_;
dataReady_ = UART_Rdy_Ptr( );
wifible_process();
if (dataReady_ != 0)
{
receivedData_ = UART_Rd_Ptr( );
switch (receivedData_)
{
case '+' :
{
command_cnt++;
if(command_cnt > 5)
{
command_cnt = 0;
}
fCommand = _WIFIBLE_NEXT_COMMAND;
break;
}
case 's' :
{
fCommand = _WIFIBLE_START_COMMAND;
break;
}
case 'e' :
{
if(fExample == _WIFIBLE_BLE_EXAMPLE)
{
fExample = _WIFIBLE_WIFI_EXAMPLE;
mikrobus_logWrite("- Example: WiFi - TCP example ", _LOG_LINE);
mikrobus_logWrite("- [+] First command // [e] Next example", _LOG_LINE);
command_cnt = -1;
fCommand = _WIFIBLE_NO_COMMAND;
}
if(fExample == _WIFIBLE_WIFI_EXAMPLE)
{
fExample = _WIFIBLE_BLE_EXAMPLE;
mikrobus_logWrite("- Example: BLE - iBeacon example ", _LOG_LINE);
mikrobus_logWrite("- [+] First command // [e] Next example", _LOG_LINE);
command_cnt = -1;
fCommand = _WIFIBLE_NO_COMMAND;
}
break;
}
}
if(fExample == _WIFIBLE_WIFI_EXAMPLE)
{
_WiFi_TCPServer(command_cnt);
}
if(fExample == _WIFIBLE_BLE_EXAMPLE)
{
_BLE_iBeacon(command_cnt);
}
}
}
Alongside with the demo application timer initialization functions are provided. Note that timer is configured acording to default develoment system and MCUs, changing the system or MCU may require update of timer init and timer ISR functions.

StringConversionAdditional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
