Returns:
0 on success, a negative number on failure

Definition at line 9 of file ESP8266Interface.cpp.

bool is_connected (  ) [inherited]

Check connection to the access point.

Returns:
true if successful

Definition at line 91 of file ESP8266.cpp.

bool join (  ) [inherited]

Connect the wifi module to the ssid contained in the constructor.

Returns:
true if connected, false otherwise

Definition at line 70 of file ESP8266.cpp.

int putc ( char  c ) [inherited]

Write a character.

Parameters:
thecharacter which will be written

Definition at line 378 of file ESP8266.cpp.

int readable (  ) [inherited]

Check if characters are available.

Returns:
number of available characters

Definition at line 360 of file ESP8266.cpp.

bool reboot (  ) [inherited]

Reboot the wifi module.

Definition at line 333 of file ESP8266.cpp.

void reset (  ) [inherited]

Reset the wifi module.

Definition at line 317 of file ESP8266.cpp.

int send ( const char *  buf,
int  len 
) [inherited]

Send a string to the wifi module by serial port.

This function desactivates the user interrupt handler when a character is received to analyze the response from the wifi module. Useful to send a command to the module and wait a response.

Parameters:
strstring to be sent
lenstring length
ACKstring which must be acknowledge by the wifi module. If ACK == NULL, no string has to be acknoledged. (default: "NO")
resthis field will contain the response from the wifi module, result of a command sent. This field is available only if ACK = "NO" AND res != NULL (default: NULL)
Returns:
true if ACK has been found in the response from the wifi module. False otherwise or if there is no response in 5s.

Definition at line 389 of file ESP8266.cpp.

bool sendCommand ( const char *  cmd,
const char *  ack = NULL,
char *  res = NULL,
int  timeout = DEFAULT_WAIT_RESP_TIMEOUT 
) [inherited]

Send a command to the wifi module.

Check if the module is in command mode. If not enter in command mode

Parameters:
strstring to be sent
ACKstring which must be acknowledge by the wifi module. If ACK == NULL, no string has to be acknowledged. (default: "NO")
resthis field will contain the response from the wifi module, result of a command sent. This field is available only if ACK = "NO" AND res != NULL (default: NULL)
Returns:
true if successful

Definition at line 402 of file ESP8266.cpp.

int writeable (  ) [inherited]

Check if characters are available.

Returns:
number of available characters

Definition at line 365 of file ESP8266.cpp.
