Got it; will do, thx.
FYI; those bold can if they want to help beta-test latest cutting-edge Koenkk’s Z-Stack_3.x.0 coordinator firmware image(s) for CC2652 Zigbee Coordinator adapters available in his development branch here:
https://github.com/Koenkk/Z-Stack-firmware/issues/439
That pre-release firmware still development that Koenkk is currently working on will as it looks right now in turn be based on TI’s SimpleLink SDK 6.41.00.17 https://software-dl.ti.com/simplelink/esd/simplelink_cc13xx_cc26xx_sdk/6.41.00.17/exports/changelog.html

Hello @Hedda,
Could you share me the schematic of this Sonoff Zigbee 3.0 Dongle Plus (P)?
I’d like to understand the way they did to make this dongle could be flashed automatically without pushing any boot button.
Thank you very much.
@chinhhut Auto-BSL (automatic BSL mode) activation/usage is explained on Electrolama’s website and cc2538-bsl readme, but note ITead/Sonoff do not implement it in standard Texas Instruments way:
https://electrolama.com/radio-docs/bsl/
https://github.com/JelmerT/cc2538-bsl/blob/master/README.md#cc26xx-and-cc13xx
Please also see the code of read cc2538-bsl, the related pull request and previous discussions there:

https://github.com/JelmerT/cc2538-bsl/issues/113
https://github.com/JelmerT/cc2538-bsl/issues/63
You can also see open-source hardware and firmware as Auto-BSL (Pin 2) is a feature most Texas Instruments CC dongles support:

If want more info you might be best of asking the same question in https://github.com/Koenkk/Z-Stack-firmware/discussions and/or Koenkk/zigbee2mqtt · Discussions · GitHub are those are larger community for TI CC hardware and firmware enthusiasts.
But if you specifically want a hardware schematic of Sonoff ZBDongle-P then you have to ask ITead:

Thank you for your detail information. I will try to research more according to your suggestion.

Thanks for your ever quick and comprehensive feedback/heads up on the subject Zigbee. Appreciated.
Can the Home Assistant Skyconnect be flashed with the ZBdongle-E firmware to act as a zigbee router device since they use the same chipset?
The “ZBDongle-P” dongle discussed in this thread does not use the same chip as Home Assistant SkyConnect as the “ZBDongle-P” dongle is based on a CC2652P chip from Texas Instruments, so I guess that you meant to post that question in the thread about “ZBDongle-E” dongle which is instead based on an EFR32MG21 chip from Silicon Labs → ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus V2” (model "ZBDongle-E") based on Silicon Labs EFR32MG21 +20dBm radio SoC/MCU
Better might be to instead ask agners that same question here → Home Assistant SkyConnect - official radio USB dongle will be compatible with both Zigbee and OpenThread (including Matter/CHIP over Thread) …or perhaps try open a new feature request issue asking to suggest a dedicated Zigbee Router firmware image for the SkyConnect dongle in this Nabu Casa repository → https://github.com/NabuCasa/silabs-firmware/issues
Regardless I would not try flashing a firmware image meant for a other adapter/board/device myself as you risk bricking it because is not only the chip that matters but the GPIO (general purpose input and output) ports/pads/pins that have been mapped for the firmware software designed for that specific circuit board that is inside each product.
That is, as the chip has multiple GPIO ports/pads/pins that could be used for many different things it is up to the developer of each circuit board to choose what port/pad/pin will be physically traced to which function and then define that by mapping the same in the firmware for that device.
There is no standard for what function GPIO pins should be mapped to, (but most do use same pads).
If you successfully flash a firmware image that did not use the same mappings then you have technically “bricked” it, in this case meaning that you can no longer flash it again via USB using the ROM Bootloader (BSL), so you must then “unbrick” it by buying/getting a cJTAG ( c/JTAG) adapter like J-Link to flash it manually via the developer pins, see → https://electrolama.com/radio-docs/advanced/flash-jtag/

Okay I am at my wits end with this dongle. I was able to flash it with firmware just fine, but I am still seeing it listed when doing lsusb as a “Silicon Labs CP210x UART Bridge” so I must have one of the early ones shipped from what I’ve read?
There’s supposedly a tool to do this, but I can’t find it anywhere, and the link i did find takes me to the sonoff site where it says the account has been “deactivated.”
So I have no clue what to do here. This is the last thing not working on my Pi, just sucks because I have a ton of sensors I’ve been waiting to test out. Any help where to source this tool would be outstanding.
As this product is still being sold I suggest you contact the official Sonoff/Itead and ask them to republish the script and tool needed to rename the USB product description on the CP2102 EEPROM.
However you should note that it only nice to have feature of USB automatic discovery which not a need to have feature, so the adapter should still be full functional, you will only need to select the device serial port and radio type manually when installing the ZHA integration.
There is more information on the USB auto discovery feature in this other thread here → Community help wanted to whitelist all compatible Zigbee and Z-Wave dongles/adapters for automatic USB Discovery in Home Assistant
Just installed the Python Z-Stack-firmware flashing method for the Coordinator Release (20230507) for the Sonoff ZBDongle-Plus (V1) on my macOS Monterey with this great and easy to follow tutorial made by Dennis van Dalen.

Just to update all, after updating the firmware to the latest version, I see far less timeout errors in logs for ZHA, just the occasional. I used to get a lot of 1byte errors, but none so far for a week.

FYI, some users are having issues with the 20230507 firmware version with new problem symtoms that they did have with the 20221226 firmware version. Koenkk have therefor compiled new test firmware and is asking for updated feedback here → Z-Stack_3.x.0 coordinator 20230901/20230902 feedback · Koenkk/Z-Stack-firmware · Discussion #474 · GitHub

Thanks Hedda, I will check it out.
I still have the same battery devices going unavailable but they still do work, they wake up after being pressed. There is one motion sensor though that does not. All routers are up however and stable. I replaced a bunch of Osram bulbs with IKEA bulbs, they were shit routers and the IKEA bulbs improved quite a bit the responsiveness of the network.
Just looking at the logs though, from a ZHA perspective it seems quite clean, just 3 timeouts, I am assuming those were the devices that became unavailable. Basically before my log used to be full of ZHA messages.
Regardless of the setup I highly reading and try following all these tips → Guide for Zigbee interference avoidance and network range/coverage optimization

Thanks Hedda, your writeup is indeed my gospel for Zigbee. I have done almost all the items there:-
- Moved my zigbee channel to 11 (Wifi channels 1,2,3 are free in my home, all my neighbours are on wifi 11)
- USB powered cable to extend the dongle to the middle of the house
- Have 2 Sonoff Dongle Plus acting as routers
I am pretty much happy with the setup so far, it is rock solid, I have 140 devices on the network so it is fairly large. 50 of them are routers, the rest end devices.
It is always the same 3 end devices that go offline, might be that they arent binding correctly, 1 is a sonoff contact sensor, 1 ikea switch and 1 aqara motion sensor. I have other same devices in the network but they are rock solid. Funny thing is that even though they are unavailable, they still work if triggered.

Hi, I have been a smartthings user for 7 years switching to home assistant. New to the community. Can you please let me know if I should buy a sonoff E or P dongle. Also looking for a z-wave dongle as I have a few z-wave devices too. Thanks
At this community we assume you are able to use the search function. This thread is specifically for the p version. Advice on what to buy can be found on lots and lots of other threads.
