WiFi Gateway (ESP8266) - reconnect to wifi router

[gohan]

Did you try latest mysensors 2.2 development?

[ThomasDr]

Hello,

do you use only the Gateway Code or is there anybody else in your code?
If you do anybody else you need delays in the code.
I think the Arduino "delay()" not the "wait()".
Wait do Mysensors things.
Delay do WIFI things.

I think you could check every minute or so if wifi connection is established and if not call the connection routine (that should be basic esp8266 stuff)

[pihome]

its basic gateway code nothing else, just copy and paste from mysensors. i added that nrf

/**
 * 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.
 * nRF24L01+  ESP8266
 * VCC        VCC
 * CE         GPIO4
 * CSN/CS     GPIO15
 * SCK        GPIO14
 * MISO       GPIO12
 * MOSI       GPIO13
 * 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.

@pihome Hello,

and what type of ESP8266 you have?
Can you try a other one?
I have some NodeMCU V0.9 with TCP and UDP in client mode with AVM Router and Repeater.
Without problems.

i dont have second esp8266 at this moment, i have order one

here is what i have and i m using it for gateway

@ThomasDr said in WiFi Gateway (ESP8266) - reconnect to wifi router:

ESP8266

[ThomasDr]

Hello,

The NodeMCU looks like my.
and your ESP8266 Arduino version?
maybe there is a new version.
What Router or Access Point do you use?

regards
ThomasD

[pihome]

Arduino 1.8.3 and ESP library is all updated. i m using vodafone router.

[ThomasDr]

Hello,

i try to build new Gateway for my Problem and Upload the same sketch, but the new Gateway do not connect to the router. I reminded the China NodeMCU have problems with Serial.begin and with WIFI.beginn. It need a delay after.
I found the WIFI.begin in the "MyGatewayTransportEthernet.cpp" file and see a wait(500). See my last post wait/delay, so I changed from wait to delay and the Gateway connect.
If you can try to change it too or change from 500 to 1000.
But i use the 2.2.0 dev.

regards
Thomas

@thomasdr thank you for the info, and sorry for late reply, changing wait(500) to delay(500) worked.
