<p>Sorry I put a comment here https://developer.legrand.com/forums/topic/nlt-nld-ota-update-process/ as I didn’t find the way to create a new topic.<br /><br />But now, I found it. So happy to go this way</p><p>I’m using a Zigbee Gateway with the Zigbee For Domoticz plugin. Until a while they were no issue to OTA upgrade any Legrand/Netatmo devices such as Cable Connect, Switch …</p><p>Today we are trying to upgrade a Cable connect from 13 to 39 version (retreived on Legrand site). All the OTA firmware process works well. It finished with the Zigbee Upgrade End Response message.<br /><br />However, the device, still behave as before, and especially when quering Cluster 0x0000, Attribute 0x4000 I still get the previous version.</p><p>I found someone in the forum talking a Legrand OTA post-upgrade. Would it be possible to have some insight please ?</p>

Hi Patrick,

I opened an internal ticket to the teams in order to investigate. If I need more information, I’ll answer to the email you sent us 🙂

I’ll tell you once I know more

<p>Leslie,<br /><br />Thanks very much. If needed I can share a Wireshark, of the all OTA. <br />At the end everything goes well, but the device still query the old version :-(</p>

Hi Patrick,

Yes, a wireshark capture would be great 🙂

Can you please send it via the WWL contact email ?
