Getting "ver mismatch"

[jocke4u]

Hi,

I noticed that I am getting a lot of "ver mismatch"

0;0;3;0;9;gateway started, id=0, parent=0, distance=0
0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0,sg=0:
0;0;3;0;9;ver mismatch
0;0;3;0;9;read: 0-0-0 s=0,c=0,t=0,pt=0,l=0,sg=0:
0;0;3;0;9;ver mismatch
0;0;3;0;9;read: 0-1-0 s=0,c=0,t=0,pt=0,l=0,sg=0:
0;0;3;0;9;ver mismatch
...etc

The ethernet gateway is running Lib Ver 1.5 and sensors 1.4; is that the reason?

How should I solve this?

Yes, upgrade.

Out of interest - do differing versions work? Ie is "ver mismatch" a warning or an error?

[hek]

It's an error. Messages with the wrong version will not be processed. But it's is only updated when the over-the-air format has been changed.

Thanks @hek. Is there a way to tell from the version when the OTA format changes from versions? ie do you bump the major version etc? I have some sensors buried away so need to be cautious of using later versions.

Yes you can look in the following file:
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/core/MyMessage.h#L39

We try to keep the OTA updates to a minimum (because of the problems you describe). I don't even think we need to bump this when going to 2.0.

Any by OTA updates you mean over the air protocol updates, not over the air firmware updates, right?

[shabba]

Yes - the serial protocol.

Mo ha ha... I will take over ALL your sensors.
