No external zigbee antenna on LM5-KCDZ

[stianj]

Hi!

I'm very intrigued by the new LM5-KCDZ, but as far as I can see there is no connector for an external ZigBee-antenna - unlike the RS232 ZigBee gateway (And Schneider SpaceLogic Hybrid for that matter)

Not sure this will work very well inside a metal closet..? Am I better off with a LM5Lp2 and the separate ZigBee gateway? Was hoping to both save a couple of TE, but mostly a RS232 interface that I can find better uses for...

Regards,
Stian

If you will use metal enclosure then better use https://openrb.com/zigbee-rs232-gateway/

Ok, thanks. That's a pity. In Norway (at least, not much knowledge of regulations in other countries) the enclosure in residential buildings has to comply with ISO 1182 - which effectively prohibits anything but metal. Of course the LM5-KCDZ can be in a separate casing outside the main enclosure, but that's rarely a good solution.

So that is indeed a pity.

I found a picture on Logic Machine Italia's Instagram, (https://www.instagram.com/p/C-iR2QvoA1d/?img_index=5) where something that at least looks like a MHF-connector is visible. But that doesn't do anything?

I had other plans for the RS232-port, that's why the KCDZ was so interesting.

Other than the CAN FT, Dali and Zigbee, is the hardware identical to the "normal" LM5 Lite? Same cpu and memory?

Thanks.

Gawking a bit more at those pictures, it looks like the LM5-KCDZ has a RF-BM-2652P2 - which is very interesting! Might we see BLE in the future?

[stianj]

Hmm. No feedback on wether the CPU and memory is the same as the other LM5 Lite?

(And about future BLE for that matter )

[Daniel]

CPU and memory is the same.
Why do you mention BLE?

[stianj]

Ok, thanks. Because looking at pictures it seems that LM5-KCDZ has RF-BM-2652P2 module from RF Star - which is a multi-protocol Zigbee/BLE/Thread module...

But I see that the image I mentioned earlier from Logic Machine Italia's Instagram is actually removed now

Yes it is but currently we are not planning to use it for anything else.
