ESP8266 Gateway with AP mode instead of hardcoded ssid etc

[UweK]

Hi
I want to change the ESP8266 gateway exampel in a way that i can use AP mode to configure the gateway on the fly instead of hardcoding SSID and PW in teh code.

But: How can i stop the gateway starting when no WIFI SSID is set to start AP mode?

I haven't understood the start phase completely.

Thanks
Uwe

@uwek
It seems as the library only supports the defined DEFINE Variable
(void)WiFi.begin(**MY_WIFI_SSID**, MY_WIFI_PASSWORD, 0, MY_WIFI_BSSID);

Has anlyone an idea how to add some flexibility?

This is how I did it

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * REVISION HISTORY
 * Version 1.0 - Henrik EKblad
 * Contribution by a-lurker and Anticimex,
 * Contribution by Norbert Truchsess <norbert.truchsess@t-online.de>
 * Contribution by Ivo Pullens (ESP8266 support)
 *
 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the WiFi link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * VERA CONFIGURATION:
 * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin.
 * E.g. If you want to use the defualt values in this sketch enter: 192.168.178.66:5003
 *
 * LED purposes:
 * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch, only the LEDs that is defined is used.
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/esp8266_gateway for wiring instructions.

 * SCK        GPIO14
 * MISO       GPIO12

 * GND        GND
 *
 * Not all ESP8266 modules have all pins available on their external interface.
 * This code has been tested on an ESP-12 module.
 * The ESP8266 requires a certain pin configuration to download code, and another one to run code:
 * - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
 * - Connect GPIO15 via 10K pulldown resistor to GND
 * - Connect CH_PD via 10K resistor to VCC
 * - Connect GPIO2 via 10K resistor to VCC
 * - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
 *
  * Inclusion mode button:
 * - Connect GPIO5 via switch to GND ('inclusion switch')
 *
 * Hardware SHA204 signing is currently not supported!
 *
 * Make sure to fill in your ssid and WiFi password below for ssid & pass.

ough!!
Cool, Soo easy, tststs...

Thanks a lot...

Hello,

but that is solution for non-MQTT GW, if you have ESP8266 with MQTT you still get

Documents/Arduino/libraries/MySensors/core/MyGatewayTransportMQTTClient.cpp:257:33: error: 'MY_WIFI_PASSWORD' was not declared in this scope
  (void)WiFi.begin(MY_WIFI_SSID, MY_WIFI_PASSWORD, 0, MY_WIFI_BSSID);

any solution for this ?
thank you

But if you move ( or sold ) your gateway to different network, what seems as reason for selecting SSID and password,
you still need recompile your code due to different IP of your controller.
