ESP8266 Gateway runs DHCP, not static



  • Running an ESP8266(NodeMCU 1.0) gateway with MY_IP_ADDRESS uncommented and MY_RADIO_NRF24 commented out, without problem. I get the desired I.P. address.
    However, when I uncomment MY_RADIO_NRF24 it starts running DHCP.
    Any ideas?

    @tekka was quick to submit a pull request for that fix, https://github.com/mysensors/MySensors/pull/772



  • You're probable right. Running GatewayEsp8266 example but I seem to recall having had the same problem with the MQTTGateway. Will test and get back with you...Thanks

    And thanks for the quick response.



  • Problem persists, running version "MySensors Library v2.2.0-beta" downloaded today.
    "



  • I have the same problem. I am not able to fix it. It seems that the order of Config and Begin are correct?!? I am also not sure why this changed if are remove the define for the radio. I am using the ethernet gateway.





  • @electrik Hi, Yes. I think so. I have create an empty sketch and upload this to the board and after that my original code. But without any improvement.

    @martim uploading an empty sketch does not clear the eeprom.
    In the MySensors examples folder/menu, there is a ClearEeprom sketch. Upload that, run it (check serial monitor) and then upload your original sketch again.



  • @mfalkvidd Thanks. I have cleared the eeprom with this and after that install the sketch again. Still DHCP.
    This is the sketch:

     * The sensors forms a self healing radio network with optional repeaters. Each

     * 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.

    This is the logging:

    connected with CycloneIT, channel 5
    dhcp client start...
    ip:192.168.10.228,mask:255.255.255.0,gw:192.168.10.1
    

    I am using MySensors 2.2.0 and Arduino 1.8.5 and download the latest boards from:
    http://arduino.esp8266.com/stable/package_esp8266com_index.json

    I am not sure what I am missing, maybe it is a simple thing in the sketch, if I comment out the #define MY_RADIO_NRF24 then it works???

    As temporary workaround, you can reserve the ip you want assigned on the dhcp server configuration (I'd guess it is your wifi router)
