ESP8266 to RS485 example

[farbod Shajjarian]

Hi everyone.

after creating a new topic about having problems with "range extender example", thanks to Dario and others i found out that it is better to use esp instead of nrf.

after waiting a few weeks i finally got my esp modules. i used the esp modules as standalone gateway and standalone peer and i am pretty sure that my hardware is okay and i know how to program the esp.

now i need to run the esp8266 to rs485 example.

there are 3 sketches there (gateway , bridge , peer) and none of them compiles in arduino ide because its incomplete

gateway:

// Configure the framework
#include "bconf/StandardArduino.h"          // Use a standard Arduino
#include "conf/ethW5100.h"                  // Ethernet through Wiznet W5100
#include "conf/Gateway.h"                   // The main node is the Gateway
#include "conf/IPBroadcast.h"               // Use IP Broadcast Communication

// Include framework code and libraries
#include <SPI.h>
#include "Souliss.h"

// Define the network configuration according to your router settings
uint8_t ip_address[4]  = {192, 168, 1, 77};
uint8_t subnet_mask[4] = {255, 255, 255, 0};
uint8_t ip_gateway[4]  = {192, 168, 1, 1};
#define myvNet_address  ip_address[3]       // The last byte of the IP address (77) is also the vNet address

void setup()
{   
    Initialize();

    // Set network parameters
    Souliss_SetIPAddress(ip_address, subnet_mask, ip_gateway);
    SetAsGateway(myvNet_address);                                   // Set this node as gateway for SoulissApp  

    // Set IPBroadcast vNet Address    
    SetAddress(0xAB01, 0xFF00, 0x0000);

    // This node as gateway will get data from the Peer
    SetAsPeerNode(0xD002, 1);
    SetAsPeerNode(0xD102, 2);
}

error:

could you please help me complete these example sketches to run this example ?

 

sorry for the long post and thanks in advance.

Dear dario.

thanks for the link but i couldnt understand anything from it. so i read the wiki page by page and tried two write some sketch from begining. i am trying to connect to arduino

gateway is uno with ethernet shield. node is uno connected using crossed tx and rx.

gateway:

#include "bconf/StandardArduino.h"          

#include "conf/ethW5100.h"                 

#include "conf/Gateway.h"    

#include "conf/usart.h"  

#include <SPI.h>

#include "Souliss.h"

#define RED          0    

#define BLUE          1    

#define Gateway_address 50

#define myvNet_address  50       

#define myvNet_subnet   0xFF00

#define myvNet_supern   Gateway_address

uint8_t ip_address[4]  = {192, 168, 1, 50};

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

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

void setup() {

Initialize();

Souliss_SetIPAddress(ip_address,subnet_mask,ip_gateway);

SetAsGateway(myvNet_address);

    SetAddress(0xCE01, 0xFF00, 0x0000);

    SetAsPeerNode(0xCE02, 1);

    Set_T11(RED);       

    

    Set_SimpleLight(BLUE);      

    

    // We connect a pushbutton between 5V and pin2 with a pulldown resistor 

    // between pin2 and GND, the LED is connected to pin9 with a resistor to

    // limit the current amount

    pinMode(2, INPUT);               

    pinMode(9, OUTPUT);                

    pinMode(3, INPUT);                 

    pinMode(7, OUTPUT);               

}

void loop() { 

    // Here we start to play

    EXECUTEFAST() {                     

        UPDATEFAST();   

        

        FAST_50ms() {   

            DigIn(2, Souliss_T1n_ToggleCmd, RED);        

            Logic_T11(RED);                         

            DigOut(9, Souliss_T1n_Coil, RED);               

            DigIn(3, Souliss_T1n_ToggleCmd, BLUE);           

            Logic_T11(BLUE);                         

            DigOut(7, Souliss_T1n_Coil, BLUE);                /

          

        } 

              

        // Here we handle here the communication with Android, commands and notification

        // are automatically assigned to MYLEDLOGIC

        FAST_GatewayComms();                                        

        

    }

} 

and node:

#include "bconf/StandardArduino.h"
#include "conf/usart.h"
#include <SPI.h>
#include "Souliss.h"


#define RED 0
#define BLUE 1

void setup() {
 
Initialize();

 SetAddress(0xCE02, 0xFF00, 0x0000);



 Set_T11(RED);
 
 Set_SimpleLight(BLUE);
 
 pinMode(2, INPUT);
 pinMode(9, OUTPUT);
 pinMode(3, INPUT);
 pinMode(7, OUTPUT);



}


void loop() {
 
 EXECUTEFAST() {
 UPDATEFAST();
 
 FAST_50ms() {


 
 Logic_T11(RED);
 DigOut(9, Souliss_T1n_Coil, RED);



 Logic_T11(BLUE);
 DigOut(7, Souliss_T1n_Coil, BLUE);
 
 }
 

 FAST_PeerComms();
 START_PeerJoin();
 
 }
}

could you guys please tell me whats wrong ??

The connection looks ok, is the usb cable connected? If so, disconnect it.

thanks for your quick response.

i disconnected the usb and powered both boards unig Vin and GND pins.

i still can not see or control the peer (only a zero health no typicall node in the app)

could you please take a look at my sketch? specially the peer ..

[Di Maio, Dario]

Change this
SetAddress(0xCE02, 0xFF00, 0x0000);

With

SetAddress(0xCE02, 0xFF00, 0xCE01);

[farbod Shajjarian]

still not working :( 

[Di Maio, Dario]

There are example in the example folder, but looks like not a problem of your sketch but of your hardware.

Are you using official Arduino/Genuino boards or clones?

well , i have access to only one supplier which sells arduino about 5 dollars when converted to USD which i think is not official comparing to 21$ arduino website.

but i have no other choice and i have to manage using it somehow because i have a lot of limit in buying hardware (even the other time i was told its better to use esp instead of nrf, i had to wait a few weeks to get the esp board) 

i have done these setups lately:

arduino ethernet gateway + esp peer = ok

esp gateway + esp peer = ok

arduino gateway + arduino peer (uart) = not ok ---> maybe ethernet shield interferes with uart??

esp gateway + arduino peer (uart) = not ok

so i think my addressing and headers are okay and there is a problem with my uart connection

in the last setup (esp gateway + arduino peer (uart)) when i opened soulissapp after some time it would load the peer node and its typical (simple led)

but it acts strange. the on off toggle is unresponsive or works really bad, and the node health (which i dont know how is calculated) is always less than half.

so i think i have to connect the nodes with another way than wifi or rf or ethernet, or i should use standalone esp nodes which i think i will have some limits using it..

[Luca Calcaterra]

Have you fixed it ? 

I'm trying to have the configuration esp gateway + arduino peer (uart)  but cannot get to work (i want to cut ethernet, it's possible? ? Thanks
