ESP8266-07 not broadcasting a signal

Hello,
I am working on a project using the aforementioned ESP and everything seems to be working great, I can program them, they output to the serial terminal what I tell them to, and the GPIO even blink LEDs.
The problem is that when I set it to be an access point, using example code and my own code, it doesnt output the SSID (I cant find it on the network). I am using the arduino IDE to program it.
Any help would be appreciated.

Unfortunately my chrystal ball is in the shop for repair this week: could you post us some code you tried?
You can Always first flash the original AT-code back and control it over serial (setting the mode to AP and entering a SSID) to see if the hardware is in working order.

These are some examples of what ive been uploading to test functionality.
Both are examples in Arduino.
Code: Select all/*
ESP8266 Blink by Simon Peter
Blink the blue LED on the ESP-01 module
This example code is in the public domain
The blue LED on the ESP-01 module is connected to GPIO1
(which is also the TXD pin; so we cannot use Serial.print() at the same time)
Note that this sketch uses LED_BUILTIN to find the pin with the internal LED
*/
void setup() {
pinMode(16, OUTPUT); // Initialize the LED_BUILTIN pin as an output
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(16, LOW); // Turn the LED on (Note that LOW is the voltage level
// but actually the LED is on; this is because
// it is active low on the ESP-01)
delay(1000); // Wait for a second
digitalWrite(16, HIGH); // Turn the LED off by making the voltage HIGH
delay(2000); // Wait for two seconds (to demonstrate the active low LED)
} Code: Select all#include <ESP8266WiFi.h>

void setup() {
WiFi.mode(WIFI_AP);
WiFi.softAPConfig(apIP, apIP, IPAddress(255, 255, 255, 0));
WiFi.softAP("DNSServer CaptivePortal example");
// if DNSServer is started with "*" for domain name, it will reply with
// provided IP to all DNS request
dnsServer.start(DNS_PORT, "*", apIP);
// replay to all requests with same HTML
webServer.onNotFound([]() {
webServer.send(200, "text/html", responseHTML);
});
webServer.begin();
}
void loop() {
dnsServer.processNextRequest();
webServer.handleClient();
