EmberZNet 7.3.2.0/7.4.0.0 firmware

[estimadarocha]

@xsp1989 do you expect to compile new version with 7.3.2 or 7.4.0?

Just a small apart dunno if this is the correct place to post it... this new versions working together with last z2m should support completely zgp devices?

Thanks

[Hedda]

@xsp1989 +1 but for newer Zigbee EmberZNet 7.3.3.0 (GSDK 4.3.3.0) and EmberZNet 7.4.1.0 (GSDK 4.4.1.0) respectivly:

https://github.com/SiliconLabs/gecko_sdk/releases/tag/v4.4.1

https://www.silabs.com/documents/public/release-notes/emberznet-release-notes-7.4.1.0.pdf

MattWestb has summarized the included fixes for Zigbee EmberZNet NCP and RCP here:

zigpy/zigpy#894 (comment)

zigpy/zigpy#894 (comment)

He mentions there that his guess is EmberZNet 7.3.3.0 might be the last bug fix for and then it will only get EmberZNet 7.3.3.x security updates. While the EmberZNet 7.4.x.x will continue to get new bug fix releases.

@estimadarocha FYI, you can also get newer unofficial firmware releases here:

Personally, I like to use the old version. The new version usually has new functions, and the new functions usually bring new bugs. Then the next few versions are to fix the bugs for this version. Of course, it is also possible It is to add new features, fix bugs, and add new bugs at the same time (joke: coding bug).

In terms of usage, a specific version may have a known problem, and you will know how to solve or circumvent the problem, so the problem may not be a problem. If a new problem arises, you may need to reanalyze the problem in order to solve it, or you can just complain.

A reason for updating is that they drop support for older versions in zigbee2mqtt

Koenkk/zigbee2mqtt#21462

I have an issue with Tims Firmware there

I've not seen anything that they have dropped ezsp backend, however the new ember backend is currently only available with 7.4.x firmwares.

I can confirm @sstidl's comment from my logs
[2024-05-05 17:55:49] warning: zh:ezsp: Deprecated driver 'ezsp' currently in use, 'ember' will become the officially supported EmberZNet driver in next release. If using Zigbee2MQTT see https://github.com/Koenkk/zigbee2mqtt/discussions/21462

I did manage to switch to Tims firmware:

Ahhhh @sstidl i'm using a one of these https://templates.blakadder.com/ewelink_ZB-GW03.html not sure how i'd go about flashing it

[raptr55]

Same here. I got this one from AliExpress
https://a.aliexpress.com/_EGwHi11

Not sure about flashing procedure and which new firmware I have to choose to fix the error

[darkxst]

using a one of these https://templates.blakadder.com/ewelink_ZB-GW03.html

I believe this requires signed firmware, so I am unable to include in my firmware builder.

[xsp1989]

I built a 7.4.3.0 firmware today. There are still some problems. If there are no problems, I will release it as soon as possible.

[xsp1989]

@jonny190 If you purchased the tasmota version, you need to use the signature firmware to refresh the zigbee firmware. If it is the ewelink version, you need to use the serial port to flash it. For details, please see https://thehelpfulidiot.com/a-wired-sonoff-zigbee-alternative

A reason for updating is that they drop support for older versions in zigbee2mqtt

I've not seen anything that they have dropped ezsp backend

Z2M have not dropped the support for it but they marked ezsp adapter as deprecated, see -> Koenkk/zigbee-herdsman#1039

Deprecated means it will no longer maintained and that users now have a grace period to migrate to the new ember adapter.

Their new ember adapter is suppose to fully replace old ezsp adapter but it does require EmberZNet 7.4.0.0 or later firmware.

• New ember adapter implementation targeting EZSP 13 and above Koenkk/zigbee-herdsman#918
• Improved Ember (EZSP) driver (experimental) Koenkk/zigbee2mqtt#21462

PS: Note that all Silicon Labs based adapters are still "experimental" in Z2M -> https://www.zigbee2mqtt.io/guide/adapters/

[xsp1989]

Firmware 7.4.3.0 has been updated, signed and unsigned versions have been released
