I entered a test program from Sparkfun to demonstrate AP mode
const char WiFiAPPSK[] = "sparkfun";
.
.
.
void setupWiFi()
{
WiFi.mode(WIFI_AP);

// Do a little work to get a unique-ish name. Append the
// last two bytes of the MAC (HEX'd) to "Thing-":
uint8_t mac[WL_MAC_ADDR_LENGTH];
WiFi.softAPmacAddress(mac);
String macID = String(mac[WL_MAC_ADDR_LENGTH - 2], HEX) +
String(mac[WL_MAC_ADDR_LENGTH - 1], HEX);
macID.toUpperCase();
String AP_NameString = "ESP8266 Thing " + macID;

char AP_NameChar[AP_NameString.length() + 1];
memset(AP_NameChar, 0, AP_NameString.length() + 1);

for (int i=0; i<AP_NameString.length(); i++)
AP_NameChar[i] = AP_NameString.charAt(i);

WiFi.softAP(AP_NameChar, WiFiAPPSK);
}

and then I altered the security login and AP_namestring
const char WiFiAPPSK[] = "TEST";
String AP_NameString = "TESTController " + macID;

My program compiles and downloads fine but then sets up a connection using the sparkfun information, not the new information

Tried lots of resets etc but always the same....

Any ideas

Wow, so much ugly code to handle this simple SSID name...
Also, beware that some clients will choke if SSID contains space characters, use dashes instead.

Thanks for that simplification, added it in, uploaded and again it did not work; reverted back to original

Your password needs to be 8 or more characters. That's why you're seeing the old values. Hope this helps!
