ESP32 Arduino SSID, PASSWORD not update

Postby senthil313 » Tue May 29, 2018 12:17 pm

i change the ssid and password through web server , i received and stored flash memory.Its all ok.
then move new ssid to real ssid and password. but it wont accept.

For the access point mode ssid password not update.
In Station mode static IP not update ...

const char* ssid ="esp"
const char*password="12345"

Give any example conversion for char to const pointer for ssid update...

I have encountered this once before...using Arduino, the SSID and password seemed to be "permanently" burned in and would not change by uploading a new sketch.

Try doing a complete force-erase manually using esptool.py.

Then reflash your program using the Arduino IDE. That should clear any existing WiFi settings that might get goofed by an Arduino sketch.

thanks for your reply...

the issue is solved using malloc.
To convert char array to function pointer...

e.g. arr = (int *)malloc(5 * sizeof(int));
