-ffunction-sections
-fdata-sections
Place each function or data item into its own section in the output file if the
target supports arbitrary sections. The name of the function or the name of
the data item determines the section’s name in the output file.
Use these options on systems where the linker can perform optimizations to
improve locality of reference in the instruction space. Most systems using the
ELF object format and SPARC processors running Solaris 2 have linkers with
such optimizations. AIX may have these optimizations in the future.
Only use these options when there are significant benefits from doing so. When
you specify these options, the assembler and linker will create larger object and
executable files and will also be slower. You will not be able to use gprof on all
systems if you specify this option and you may have problems with debugging
if you specify both this option and ‘-g’.
- begin changes
allow setting BSSID/MAC and Channel of an AP for faster connection (#261)
now checks if ssid and passphrase to big
selecting Wifi mode in better way (fix for #28)
- ESP8266WiFiMulti uses the new functions to auto select best AP even in a multi AP WiFi network (more the one AP has same SSID)
- add new functions to get current Connected AP:
uint8_t * BSSID(void);
int32_t Channel(void);
- add new functions to get infos from scanned networks:
uint8_t * BSSID(uint8_t networkItem);
int32_t Channel(uint8_t networkItem);
bool isHidden(uint8_t networkItem);
bool getNetworkInfo(uint8_t networkItem, const char** ssid, uint8_t * encryptionType, int32_t * RSSI, uint8_t ** BSSID, int32_t * channel, bool * isHidden);
Serve files from the onboard flash
Edit them with the included file manager (http://esp8266fs.local/edit)
Create simple graphs filled with sensor data with the included simple
library (example is the index page, editable through the editor)
The sketch uses the new extension for packing files into SPIFFS image
and uploading it to your ESP8266
