How to print routing table in serial console?

hek

You have to read it from eeprom.
It starts at position: EEPROM_ROUTES_ADDRESS (defined in MySensors.h)

@hek you are right! There was an entry for Node-2 in Node-1 routing table, As it has direct access to Node-2, was trying to send directly. I removed the entry and now it's going throw gateway. All node works well. Perfect!

I thing we have to add code to remove routing table entry dynamically if it face some N number of failures. It will make life easier for those who is shifting node from one location to another location often.

Hello,

Sorry to resort to an old topic ...
I am currently using mysensors RS485, and I would like to extend my installation with this protocol.
and I would like to make the nodes communicate with each other through the gateway.
But I can't do what I want ... help!
on my node 4, I have an input and 1 output, the input activates and deactivates the output. (here no worries).
On my node 5, I have an input to activate the output of node 4, so I can turn it off but not turn it on, and I don't see any frames towards the gateway

here is the code for my node 5:

// MySensors 
#define MY_PARENT_NODE_ID 0                   // define if fixed parent
#define MY_PARENT_NODE_IS_STATIC
#undef MY_REGISTRATION_FEATURE                  // sketch moves on if no registration
#define MY_NODE_ID 5                     // fixed node number

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable RS485 transport layer
#define MY_RS485

// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 2

// Set RS485 baud rate to use
#define MY_RS485_BAUD_RATE 9600

// Set blinking period
#define MY_DEFAULT_LED_BLINK_PERIOD 300

// Flash leds on rx/tx/err
//#define MY_DEFAULT_ERR_LED_PIN 4  // Error led pin
//#define MY_DEFAULT_RX_LED_PIN  5  // Receive led pin
//#define MY_DEFAULT_TX_LED_PIN  6  // the PCB, on board LED


// Enable this if RS485 is connected to a hardware serial port
//#define MY_RS485_HWSERIAL Serial1
//#include <MqttClient.h>
#include <SPI.h>
#include <MySensors.h>
#include <Bounce2.h>

#define CHILD_ID 4
#define BUTTON_PIN  3  // Arduino Digital I/O pin for button/reed switch

Bounce debouncer = Bounce(); 
int oldValue=0;
bool state;

// Change to V_LIGHT if you use S_LIGHT in presentation below
MyMessage msg(CHILD_ID,V_LIGHT);

void setup()  
{  
  // Setup the button
  pinMode(BUTTON_PIN,INPUT_PULLUP);
  // Activate internal pull-up
  //digitalWrite(BUTTON_PIN,HIGH);
  
  // After setting up the button, setup debouncer
  debouncer.attach(BUTTON_PIN);
  debouncer.interval(5);
  
}

void presentation() {
  // Register binary input sensor to gw (they will be created as child devices)
  // You can use S_DOOR, S_MOTION or S_LIGHT here depending on your usage. 
  // If S_LIGHT is used, remember to update variable type you send in. See "msg" above.
  sendSketchInfo("Button", "1.1");

  
  present(CHILD_ID, S_LIGHT);  
}


//  Check if digital input has changed and send in new value
void loop() 
{
  debouncer.update();
  // Get the update value
  int value = debouncer.read();
  if (value != oldValue && value==0) {
      msg.setDestination(4);
      send(msg.set(state?false:true), false);// Send new state and request ack back
  }
  oldValue = value;
}

@FullMetal Imo, you have to specify all send-settings in one line, e.g. like this:

send(buttonMsg.setDestination(MY_SISTER_NODE_ID).setSensor(CHILD_ID_RESET).set( button[i] ? "1" : "0"));

FullMetal

@rejoe2
thank you for your return,
but I have the same problem, I manage to activate the relay of node 4 from node 5, but I cannot deactivate it. and when I act on node 5 the gateway does not receive frames since it calls node 4.
I think that node 4 should send the relay status to node 5 so that it knows whether it is activated or not.

tekka

@FullMetal Please post a full debug log of both nodes showing the observed behaviour.

rejoe2

@FullMetal Pls add also code from node 4.

In general:

if you want also info from node 5 to be sent to your controller/gateway, you have to add a second (normal) send command.
wrt. to how node 4 reacts on the messages, you may better use sth. like a toggle logic.

}

From node 4, my output is activated and deactivated immediately, due to double sending

from node 5, I can activate or deactivate if I launch the command from node 4 before otherwise.

I just found!

ask the gateway not to send back acq
send(msg.setDestination(MY_PARENT_NODE_ID).setSensor(CHILD_ID).set(state?false:true), false); // Send new state and request ack back
wait(100);
send(msg.setDestination(SYSTER_ID).setSensor(CHILD_ID).set(state?false:true), true);

rejoe2

Good to her you found that point :smile:.
Imo you'd better change also your receive functions to not react on "ack" messages (via "else" prior to message.type-comparison).
