Reusing arduinos?

[hek]

Set a static id of 42 like this.

gw.begin(NULL, 42)

Still, doesn't fix your ack problems that probably will lead to unnecessary parent-node-searches.

I have no idea why but I was able to reuse 2 of my 4 boards like this no idea what changed or why. May just need to give it time?

As for me clearing the EEPROM of the board & restart of Vera (shutting off the power for couple of minutes) helped. Vera included early ignored board with the id1 (my first node was deleted from Vera about month ago).
Thanks to hek for advise.

I'm having a similar issue with a pro-mini clone. If I run the erase eeprom sketch, it completes, but if I then run the eeprom sketch to show all the values in the eeprom, it returns quite a few non-zero values, so not sure why it's not completely erasing. I used the gw.begin(NULL, xx) command to assign a node number to it for now.

Strange. Could the clearing-sketch be writing to fast for the eeprom to handle it?

@Sparkman

If you mean EEPROM values above address 512 then you are right. The sketch only writes from 0 to 512. Your pro mini EEPROM however has 1024 addresses. Does this make sense?

[hek]

Yes, but the id, parent and routing is in the lower region.

[Sparkman]

@hek Which addresses are those values stored in? I'll create a sketch to run the erase slower and after each erase read the value from the address that was just erased and see how it behaves.

@HarryDutch The read sketch showed values in the lower addresses as well after I ran the erase sketch.

@hek Great, thanks!
