Compilation errors on an ESP8266

[stef mertens]

Hi,

I have a gateway running on an arduino mega with ethernet and an RS485 connection (with no nodes connected to it just yet), works well. - I can connect to the gateway through Soulissapp 

I want to set up a supernode on an ESP8266, also with a RS485 connection, to act as a bridge between the gateway and more RS485 nodes.

The end setup should be:

Gateway <> ethernet <> ESP <> RS485 > node1 > node 2 ...

        |                               ESP <> RS485 > node 3 > node4 ...

        |

      RS485 > node 5 > node 6

I took some example code to start with for the ESP.:

// Let the IDE point to the Souliss framework

#include "SoulissFramework.h"

// Configure the framework

#include "bconf/MCU_ESP8266.h"              // Load the code directly on the ESP8266

#include "conf/SuperNode.h"                   // The main node is the Gateway, we have just one node

#include "conf/usart.h"                      // USART / RS485 transceiver

#include "conf/IPBroadcast.h"

// **** Define the WiFi name and password ****

#define WIFICONF_INSKETCH

#define WiFi_SSID               "xxx"

#define WiFi_Password           "xxxxxxxx"    

// Include framework code and libraries

#define USARTDRIVER_INSKETCH

#define USART_TXENABLE          1

#define USART_TXENPIN           5

#define USARTDRIVER             Serial

// Include framework code and libraries

#include <ESP8266WiFi.h>

#include <EEPROM.h>

/*** All configuration includes should be above this line ***/ 

#include "Souliss.h"

// This identify the number of the LED logic

#define MYLEDLOGIC          0               

// **** Define here the right pin for your ESP module **** 

#define OUTPUTPIN           4

void setup()

{   

    Initialize();

    uint8_t ip_address[4]  = {192, 168, 80, 181};

uint8_t subnet_mask[4] = {255, 255, 255, 0};

uint8_t ip_gateway[4]  = {192, 168, 80, 1};

#define myvNet_address  ip_address[3]    

    // This is the vNet address for this node, used to communicate with other

    // nodes in your Souliss network

    SetAddress(0xAB02, 0xFF00, 0x0000);

    SetAddress(0xCE01, 0xFF01, 0xAB02);

    SetAsPeerNode(0xCE02, 1);

    

    Set_SimpleLight(MYLEDLOGIC);        // Define a simple LED light logic

    

    pinMode(OUTPUTPIN, OUTPUT);         // Use pin as output 

}

void loop()

{ 

    // Here we start to play

    EXECUTEFAST() {                     

        UPDATEFAST();   

        

        FAST_50ms() {   // We process the logic and relevant input and output every 50 milliseconds

            Logic_SimpleLight(MYLEDLOGIC);

            DigOut(OUTPUTPIN, Souliss_T1n_Coil,MYLEDLOGIC);

        } 

              

        // Here we handle here the communication with Android

        FAST_GatewayComms();                                        

    }

} 

The gateway has IP 192, 168, 80, 180, and vnet address 0xAB01.

The code doesnt want to compile.

This is the error i get: (sorry it's in dutch)

Fout bij het compileren van board NodeMCU 0.9 (ESP-12 Module)

This report would have more information with

option enabled in File -> Preferences.

  Any idea what could be wrong here?

Thanks

A supernode is not a gateway, so you should not process FAST_GatewayComms();  but the Peer ones instead.

Regards,
Dario.

Thanks, it compiles now... Did it through remote desktop while on the train, and i will check if communication works when I get back home.

It won't you have to correct the addresses, there is an example on the wiki that fits your case.

Do not forget routing path (either dynamic or static)

Ok, i see now. That's a very nice explanation. Seems like the documentation had a major update since my last experiments with Souliss last year, thanks for that!

Hi Dario,

Can a bridge contain any typicals? I have set-up the esp8266 as a bridge, following the instructions provided in your link. No RS485 nodes are connected to it yet. I made 2 T19's in its sketch, but soulissapp "finds" the node, but does not see the typicals defined on it. Als, the health from the ESP node is very low. 

I can ping it, and it has nice responsetimes.

Thanks,

Stef

Yes it can behave as any other node.

You have defined your nodes in the Gateway, so SoulissApp has the full list even if there is no connection with those (so healthy is low).

Your Gateway and your Bridge will communicate via IP so you should see the T19s of the Bridge regardless the RS485 connectivity.

Get your Bridge online and visible in SoulissApp then move to RS485.

Dario.
