Recurrent scheduled functions will always be running in background.
esp_delay()'s interval (intvl_ms) is internally kept to its highest value allowing to honor recurrent scheduled functions requirements.
It transparently allows to keep with the arduino and nonos-sdk trivial programming way and still use background services or drivers running regularly.
* Remove warnings, errors during host tests in CI
Debug strings often included format parameters which did not exactly match
the passed in format parameters, resulting in warnings in the host test build
process like
````
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiAP.cpp:107:20: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘size_t’ {aka ‘long unsigned int’} [-Wformat=]
107 | DEBUG_WIFI("[AP] SSID length %u, too long or missing!\n", ssid_len);
| ~~~~~~~~
| |
| size_t {aka long unsigned int}
````
Fix by applying casting or PRxxx macros as appropriate.
Also, fix one debug message which was trying to use a `String` as a `char *`:
````
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiMulti.cpp: In member function ‘wl_status_t ESP8266WiFiMulti::connectWiFiMulti(uint32_t)’:
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiMulti.cpp:331:34: warning: format ‘%s’ expects argument of type ‘char*’, but argument 3 has type ‘String’ [-Wformat=]
331 | DEBUG_WIFI_MULTI("[WIFIM] Connecting %s\n", ssid);

* Clean up SpeedTest.ino host build
esp_yield() now also calls esp_schedule(), original esp_yield() function renamed to esp_suspend().
Don't use delay(0) in the Core internals, libraries and examples. Use yield() when the code is
supposed to be called from CONT, use esp_yield() when the code can be called from either CONT or SYS.
Clean-up esp_yield() and esp_schedule() declarations across the code and use coredecls.h instead.
Implement helper functions for libraries that were previously using esp_yield(), esp_schedule() and
esp_delay() directly to wait for certain SYS context tasks to complete. Correctly use esp_delay()
for timeouts, make sure scheduled functions have a chance to run (e.g. LwIP_Ethernet uses recurrent)

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
- 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);
- 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
