Problem getting the code to run with MySensors library 2.0

ayo

So I tried the whole code thing again as you have requested and I notice something weird happening to the device.
This is the code below

//// Enable debug prints to serial monitor
//#define MY_DEBUG 
//
//
//// Enable and select radio type attached
#define MY_RADIO_NRF24
////#define MY_RADIO_RFM69
//
//// Set LOW transmit power level as default, if you have an amplified NRF-module and
//// power your radio separately with a good regulator you can turn up PA level. 
//#define MY_RF24_PA_LEVEL RF24_PA_LOW
//
//// Enable serial gateway
//#define MY_GATEWAY_SERIAL

#include <SPI.h>
#include <MySensors.h>  

void setup() { 
  // Setup locally attached sensors
  pinMode(8, OUTPUT);
}

void presentation() {
 // Present locally attached sensors 
 Serial.println("Presentation Runs");
}

void loop() { 
  // Send locally attached sensor data here 
   digitalWrite(8, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(8, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
  Serial.println("Loop is running");

}

After I commented out #define MY_GATEWAY_SERIAL nothing really happens on the serial monitor as you have said.
No blinking nor display on the monitor.

So I went back to the code and enable #define MY_DEBUG to see what was actually happening....

THEN..I figured out what was happening
I uploaded the new code with #define MY_Debug uncomment and #define MY_Gateway_Serial still commented out I got this one the serial monitor

From the result, the device is working as a node and trying to communicate with the parent/gateway and it enters an endless retry loop that keeps trying to communicate with the gateway. This is the reason i suppose nothing seems to be working because it is stuck trying to connect to the parent.
The Addition of #define MY_GATEWAY_SERIAL makes it already a gateway/parent device and avoids that endless loop thing.

@ayo Did you try running the code?

ayo

I think one way to go about making it work is to edit that element of the mysensor main code that makes it enter an infinite retry loop is to is to make it retry for about maybe 3 times if no connection still it should raise a flag and leaves the loop and continue into the main code.

palande.vaibhav

@ayo
But adding #define MY_GATEWAY_SERIAL to the code for the sensor node will make it a gateway. Right? Please check my last post where I posted the screenshots of this making both of them initialize as the gateway.

And if both are gateways they won't communicate

ayo

Yes they won't communicate

@ayo
Then this makes library 2.0 completely useless cause we always have to use MY_GATEWAY_SERIAL and so can't create sensor nodes.

If you also confirm this then I am gonna report this as a bug.

ayo

No it is not like that.

You can create sensor nodes without the MY_Gateway_Serial thing, you just have to make sure that you have one device acting as a gateway device and the rest as a sensor node and everything will work very fine.

The reason you are having problem is because you are only building with one device and the library requires at-least 2 devices to work.

@ayo
How can I make sensor nodes with the MY_GATEWAY_SERIAL line in the code. This just makes the device a gateway. How do I make it a sensor node with that line included?

Just having two different devices in the same code will work??

I was able to make the blinking thing run with #Define MY_GATEWAY_SERIAL commented out by having another Arduino Uno runing the gateway serial program. Basically you will need two devices setup to work or you could make use of this hack
too which will also make your device work too without having to connect to the parent.

Go to your library folder and find the mysensors library folder open it and look for the core folder open the MySensorCore.cpp file make sure you have a backup of that file before opening it.

Find this section of the code

#if defined(MY_RADIO_FEATURE)
		// Save static parent id in eeprom (used by bootloader)
		hwWriteConfig(EEPROM_PARENT_NODE_ID_ADDRESS, MY_PARENT_NODE_ID);
		debug(PSTR("Starting Connection Process\n"));
		transportInitialize();
		// My modification should be removed for later
		debug(PSTR("Starting Connection Process 2\n"));
		int counter = 0;
		while (!isTransportOK()) {
			hwWatchdogReset();
			transportProcess();
			//debug(PSTR("Trying to connect to parent \n"));
			#if defined(ARDUINO_ARCH_ESP8266)
				yield();
			#endif
			counter++;
			if (counter >= 3) // exit after 3 attempts to connect
				break;
		}
		debug(PSTR("Starting Connection Process 3\n"));
	#endif

You can replace that section with those or just make those modification you see.
Save and try to upload your program again with the #define MY_Gateway_Serial thing commented out and the program will still run.

What that modification does is to exit the loop after 3 connection attempts.

I meant without the MY_Gateway_Serial thing

Oh I get it now. Now I understand. I must have a gateway and at least one sensor node running for this to work. If there is no gateway then sensor nodes don't work because of the constant loop trying to find a parent.

My problem was I was trying to write and run the code with just the sensor node.

I will also do the modifications you mentioned to the core files.

Thanx a lot for your help. I really appreciate it. :+1:

ayo

That's correct :)

Problem getting the code to run with MySensors library 2.0
