----------------------------- Remove above -----------------------------
Hardware:
Board: ESP32 Dev Module
Core Installation/update date: esp has not been updated firmware is about 2 years old
IDE name: Arduino IDE
Flash Frequency: 40Mhz?
Upload Speed: 115200?
Description:
the esp32 wont connect to my network it just says connecting to wifi over and over and never connects
it was working then it stopped could updating the esp32 firmware fix this or is it another issue , also is there a different way to connect to wifi that's different to the :
WiFi.begin(ssid,password);
while (WiFi.status() != WL_CONNECTED) {
Serial.println("Connecting to WiFi..");
delay(300);
}
that might fix this issue
