ESP + RFM69 Gateway Reset issue

  • Hi all,

    Firstly I'm so impressed with the community and the development on MySensors, it's great how the whole DIY IoT thing has boomed over the past couple of years.
    I'm trying to get the ESP Gateway example working with a RFM69 radio and having some issues it connects to my Wifi network fine, then fails shortly afterwards, at the same point every time. I've included a dump of the Serial from one full iteration and also a quick photo (though it's not that clear with all the wires) of my setup. Suffice to say it's basically just a normal ESP12 setup connected to the RFM69 as the documentation says.

    I'm using the latest versions of everything also.
    If anyone has any ideas they would be really appreciated.

    @OpticFroggy areyou using an unmodified(except configuration settings) example sketch? If not, could you post your sketch? Remember to censor your wifi password before posting.

  • Hey,
    Yea it's the ESP8266 Gateway sketch, unmodified except for the various defines I'd need afaik.

     * 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.

     * 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.
     * 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:
     * 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 for wiring instructions.

    @OpticFroggy sorry for the late reply. I haven't used rfm radios before, but tonight I finally got it working, with a lot of help from @scalz and the rest of the MySensors team.
    This is my wiring:
    0_1487971221147_connect_nodemcu.png 0_1488012242199_IMG_1614.PNG

    These are my settings in the sketch:

    #define MY_RADIO_RFM69
    #define MY_RFM69_FREQUENCY RF69_433MHZ
    #define MY_IS_RFM69HW
    #define MY_RF69_IRQ_PIN D1
    #define MY_RF69_IRQ_NUM MY_RF69_IRQ_PIN
    #define MY_RF69_SPI_CS D2 // NSS

    D8 cannot be used because it interferes with uploading sketches.

    With this, I got an nodemcu rfm69H-433 ethernet gateway working, and a wemos d1 mini rfm69H-433 sensor node. I used MySensors 2.1.1.
