Modify Node ID?

[tcontrada]

Is there a way to modify the Node ID once a Node ID has been issues to a sensor node that was originally configured in AUTO Node ID mode?

Thanks,
Tony

@tcontrada
I think only way is to clear eeprom and then use NODE number in gw.begin

Eg. gw.begin(NULL, 12, true)

You can use this code to change the node ID without erasing the rest of the eeprom:

#define MY_CORE_ONLY

#include <MySensor.h>
#define NEW_NODE_ID 42 // Change 42 to the new node ID you want

void setup()
{
  Serial.begin(MY_BAUD_RATE);
  Serial.print("Old node ID: ");
  Serial.println(hwReadConfig(EEPROM_NODE_ID_ADDRESS));
  Serial.println("Writing new ID");
  hwWriteConfig(EEPROM_NODE_ID_ADDRESS, NEW_NODE_ID);
  Serial.print("New node ID: ");
  Serial.println(hwReadConfig(EEPROM_NODE_ID_ADDRESS));
}

void loop()
{
  // Nothing to do here...
}

The output will look like this:

Old node ID: 69
Writing new ID
New node ID: 42

I have tested this code with the MySensors development version only, but I think it should work on older versions as well.

This looks good, thanks!

@tcontrada and if you want to get new node id request, just write new node id as 255.

I tried the short program above, but at compile time It got this error:
'hwReadConfig' was not declared in this scope

Any suggestions?

@tcontrada I guess you are using 1.5 branch, If I am not wrong hwReadConfig and hwWriteConfig are not available in 1.5. Which is available in development branch(2.0 beta).

My guess!! In 1.5 equivalent functions are hw_readConfig and hw_writeConfig

Yeah, I dug through the .h files and found the right spellings and got it to finally work...

Thanks...
