khoih-prog / ESPAsync_WiFiManager

This is an ESP32 (including ESP32-S2 and ESP32-C3) / ESP8266 WiFi Connection Manager, using ESPAsyncWebServer, with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson 6.0.0+ as well as 5.13.5- . Using AsyncDNSServer instead of DNSServer now.

connectMultiWifi not declared in this scope... #9

Closed tpalaz closed 4 years ago

Good afternoon.

Please check the below log to see full error. None of the examples in this library work.

Removing the "connectMultiWifi" function does indeed fix the error and allows compile but it breaks the program as the WiFi hangs and does not connect. 

erbose mode can be enabled via -v, --verbose option

This issue was mentioned and closed in

Compile Error on Platformio

It's platform/compiler-settings dependent and you can solve by adding the forward declaration as follows:

...
String separatorLine = "===============================================================";

uint8_t connectMultiWiFi(void);

//format bytes
String formatBytes(size_t bytes) 
...

Will update the examples soon to change.

Hi @tpalaz

Just let you know the new ESPAsync_WiFiManager release v1.1.2 already fixes the issue as well as some bugs in examples.
