Thank you.
So, in order to upgrade the dongle to the latest z2mqtt firmware we have to do all that complicated stuff?
I have now a cc2531 and am planning to upgrade. Im waiting to the end of November because according to Iteads web page they will have more stock available by then.
No. Go to section 1.2.2
https://sonoff.tech/wp-content/uploads/2021/09/Zigbee-3.0-USB-dongle-plus-firmware-flashing-1-1.docx
No you don’t. Just push the button and use TI’s Flash Programmer2 software.
No. I only posted those as alternative options to upgrade it without opening it or upgrading via Windows, and by including several different alternatives I made it more it sound more complex than it needs to be.
If have a Windows computer then the easiest is to follow Sonoff’s guide for Smart Flash Programmer 2. The downside with that is need to open the enclosure for button access to manually enter boot mode.
Not being able to enter BTL via “Auto BSL” using the software would mean not upgrading remotely.
That said, if don’t need alternatives or know why then follow this guide made simpler with fewer steps:
The main benefit of this method is that don’t need to open the dongles enclosure/casing, (this method could also be made to work across Windows, MacOS and Linux platforms if modify uartLog.py or better yet patch cc2538-bsl with working delays for CP2102N dongle uses).
python -m pip install --upgrade pip setuptools wheel gevent cc2538C:\temp\uartLog.py to get option and enter correct number for COM port (note that this step would no longer be needed in the future if and when “Auto BSL” gets patched with working delays for Sonoff USB Plus dongle in the cc2538-bsl script).python cc2538-bsl.py -p COM5 -evw C:\temp\CC1352P2_CC2652P_launchpad_coordinator_20210708.hex (replacing COM5 with correct COM port and right name/version and location of unpacked firmware file).Again, this guide could relatively easily be translated to Linux or Mac OS and be further automated via scripting, (the problem there is that the uartLog.py script from Sonoff has been hardcoded for Windows COM ports so the port manager in it needs to be modified).
Tip! cc2538-bsl can be replaced by experimental llama-bsl fork if willing to test it, though it has same “Auto BSL” delay issue with Sonoff USB Plus dongle, but developer of llama-bsl is considering adding several additional features that will make it more user-friendly than cc2538-bsl:

PS: ITead/Sonoff own developers could of course have made this much simpler if they themselves submitted patches to cc2538-bsl script.
Thank you. I am using linux.
I’ll report back when/if there is stock and test the dongle 
Hi all having trouble identifying which usb device this is when it’s plugged into HA. What device ID are you using in your zigbee2mqtt config?
Ahhh, I thought it could be that. Thanks so much.
Not sure what I am doing wrong, hopefully someone here can point out what’s wrong as after 20 minutes on the new coordinator the devices still aren’t connected.
I am coming from a CC2531 running 1.2 firmware and going to the sonoff zibgee stick 3.0, which I have flashed with CC1352P2_CC2652P_launchpad_coordinator_20210708. Z2M is running version 1.22 and there are no errors in the log other than when I try to turn a light off and it times out on receiving a signal. I stopped z2m unplug old coordinator, plug in new coordinator. Put the new serial id in (see below) and start up z2m. I have given up twice now and put in the old coordinator and everything just works still. Any pointers would be appreciated.

Did you try to re-pair ?
Thanks for the reply, do you mean re-pair each device or is there some global re-pair?
FYI, Everything Smart Home channel on YouTube posted a guide about ZHA backup and migrations.
He explain why backups are important and shortly how to migrate to ITead’s Sonoff Zigbee 3.0 USB Dongle Plus from another Zigbee dongle/stick/adapter using a hacked Sonoff ZBBridge as an example:
https://www.youtube.com/watch?v=ql58ZfXso1M&ab_channel=EverythingSmartHome
Other than talking to ZHA decs I guess that much of the information comes from these other threads:
PS: Also check out this request/suggestion to add backup features to ZHA’s UI and do nightly backups:
I just realised I may have missed a step when flashing the Sonoff stick, did you copy over your original IEEE mac address onto the new stick? It says optional in the Z2M instructions.
FYI, Koenkk made a “dev” pre-release of Z-Stack_3.x.0 20211114 community version for this as others:
https://github.com/Koenkk/Z-Stack-firmware/tree/develop/coordinator/Z-Stack_3.x.0
Note! CC1352P2_CC2652P_launchpad_coordinator_20211114 is a pre-releaser so not fully tested yet!
Z-Stack_3.x.0 20211114 community firmware is based on latest SDK which contains many bug-fixes:
20 dBm output power still not enabled so CC2652P will perform as 5 dBM CC2652R/CC2652RB, see:
https://github.com/Koenkk/Z-Stack-firmware/issues/323
Also, FYI, there is no real news on community firmware with Hardware Flow Control enabled, see:
I’ve tried Z-Stack_3.x.0 20211114 on this adapter and I had a hard time getting connections to my Zigbee devices. I am on ZHA though, not sure if that makes a difference. I had to fall back to CC1352P2_CC2652P_launchpad_coordinator_20210708. Hopefully someone else can try and perhaps it was just user error.
FYI, there are known issues with connection and joining using Zigbee router devices from some brands.
If possible start by upgrade the firmware on all your Zigbee devices that acts as Zigbee routers (usually mains-powered devices), and when troubleshooting see if Zigbee end-devices (usually battery-powered devices) with connection issues are connected to Zigbee Zigbee router(s) of the same type and brand or the same manufacturer. The issue could be that one or more of your Zigbee router devices is not properly routing all messages that should be routed through it.
Recently I had the opportunity to test the new Zigbee usb dongle from Sonoff (https://itead.cc/product/sonoff-zigbee-3-0-usb-dongle-plus/). Two main reasons to do this: a remarkable solid build device at an attractive price based on TI CC2652P + CP2102N chipset.
I have tested the Sonoff Zigbee dongle on a virgin RPI-4 HA installation.

Now let’s plug it in and see what’s happening:
Ai, I was expecting something else, better ignore. Apparently HA is recognising this as a ZWave device.
Let’s now install ZHA (Zigbee Home Automation) and select the Zigbee radio from the integration:
How powerful is this device? I am going to try pair a couple of zigbee units at 15 m from the dongle and with a few concrete walls and ceilings in between the dongle and the zigbee units.
My first conclusion: a solid device at a competitive price with a good range for home zigbee appliances.
Can you compare LQI values for motion sensor with sonoff and pre-sonoff?
Good idea, will do.
