Fixed critical issues WiFiMulti library:
- WiFi scan timeout implemented to prevent endless connect loop
- Fallback implemented on WiFi connect failure to prevent endless loop
- Fast WiFi connection at startup
- Improved debug prints
- Doxygen added
- Code maturing
- Example update
Make functions not related to ESP8266WiFiMulti class static
Revert static functions startScan and printWiFiScan()
Use PolledTimeout.h to protect while loops
Move static functions beginning of the file
Add connect timeout to example
* fix DEBUG macros
All fmt strings in flash
fix#5658
This also allows to avoid warnings and easy mistakes with (no brace):
if (something)
DEBUGV("blah");
* use newlib unaligned-compatible printf for DEBUGV
* remove useless putprintf since ::printf already uses ets_putc
- auto select ssid with best signal
- for debugging enable DEBUG_WIFI_MULTI macro and call Serial.setDebugOutput(true);
change ESP8266WiFiClass::status() return type to wl_status_t
