Intermediate API

Rather than attempt to anticipate every new ESP command or user requirement, a low-level API allows you to easily interact with the ESP device in custom ways. Alternatively, the ESP8266 class can be extended.

bool commandok(const char *cmd)

The above command issues the command string followed by a CR LF. It returns when one of OK, FAIL or ERROR is received.

The following methods clear builtin flags used by the class receiving engine:

void clear_flag_ready()
void clear_flag_wifi_connected()
void clear_flag_got_ip()        
void clear_flag_ok()            
void clear_flag_fail()          
void clear_flag_dnsfail()       
void clear_flag_error()        

Upon return from commandok(), you can test if the messages received set the flag of interest:

bool get_flag_ready() const     
bool get_flag_wifi_connected() const
bool get_flag_got_ip() const        
bool get_flag_ok() const            
bool get_flag_fail() const          
bool get_flag_dnsfail() const       
bool get_flag_error() const
