Description
I'm just doing a simple thing, namely connection to an access point, which used to work fine when using lua/nodemcu with this access point, but refuses to work using this framework.
The strange thing is, it does work when I connect to my phone's Wi-Fi hotspot, but doesn't work when connecting to my regular access point (a Asus WL-500gP running Tomato).
I tried everything I could think of on the access point:
- switch channels
- switch mode between b and g (it doesn't support n)
- rename SSID
- change password
- change encryption to WPA1/TKIP or to WPA1/WPA2 compatible TKIP or EAS
But none of them fixed the problem
Sketch
I've simplified it to just the basic steps/example code. Added the network scan so it shows that the SSID does exist and is found by the esp8266. So at the very least the debug message no SimonAP found, reconnect after 1s is wrong.
#include <ESP8266WiFi.h>
void setup() {
Serial.begin(115200);
Serial.setDebugOutput(true);
Serial.println();
Serial.println("Starting setup");
Serial.print("Scan start ... ");
int n = WiFi.scanNetworks();
Serial.print(n);
Serial.println(" network(s) found");
for (int i = 0; i < n; i++)
{
Serial.println(WiFi.SSID(i));
}
Serial.println();
WiFi.disconnect(true);
WiFi.setAutoConnect(false);
WiFi.setPhyMode(WIFI_PHY_MODE_11G);
WiFi.begin("SimonAP", "thisisapassword");
WiFi.printDiag(Serial);
Serial.println(WiFi.getPhyMode());
Serial.print("Connecting");
while (WiFi.status() != WL_CONNECTED)
{
delay(500);
Serial.print(".");
}
Serial.println();
Serial.print("Connected, IP address: ");
Serial.println(WiFi.localIP());
delay(2000);
}
