@p.kaczmarek2 I was based on the list here: https://openbekeniot.github.io/webapp/devicesList.html where it is the same socket and the same module.
I can try to take the plate off. Is it somehow soldered to the module? do you have to or are there other ways?

You can try hot air with the right amount of flux, you can also try to add ordinary lead binder, but I don't know how much space there is and what module it is.

Or provide more complete logs instead of downloading the screen.

This is what the log from BK7231 looks like, do you get such a log in the UART?

There was a sticker on the other side of the module. When I removed it, this message appeared:

For 99% it is NOT BK7231T but some F8088 from Foneric or something similar. The rest of the logs confirm this:

Their site... is not very helpful :-\ https://www.foneric.com/fusion-sdk
On the main page there is a button "Start your Adventure with us!" and you can email them.

Honestly, this is the first time I see something like this too.

PS Maybe it's worth adding information about this weirdo to https://openbekeniot.github.io/webapp/devicesList.html? Because I was misled that it is BK7231T

I've uploaded a fix. From what I can see, the entry about MW013_V02 comes from a post by some user who described two sockets in one post, so some error could have crept in.

I saw it. But no one made a custom batch for this chip, so even if you managed to throw something in, it's not much.

Unfortunately I do not have. I didn't even try to enter them.
But if necessary, I can solder it again and check.
Only ... there are quite a lot of combinations so I'd be happy to take suggestions as to what exactly we want to know.

Hi,

Long time no see

Just compiled and updated my Nedis Smart plug and got changed MAC-address C8478C000000. I can not change it back to original.

Edit. That "Restore RF config" fixed this, so by gone

Cheers Timo

He is preparing a teardown from a decorative LSC 970729 bulb (for which there is no cloudcutter profile) in which all electronics sit in an E27 socket.
I managed to extract the electronics, desolder the WBL5C module, rip the 2MB batch using CH340 and BKwriter, but I can't upload anything for nothing.
I tried:
- normally using RX1, TX1
- with external 3.3V power supply
- by soldering to RX2 TX2
- desoldering RX1
- using different speeds
- using NodeMCU v3 with ESP disabled
I thought that maybe something from the TX1 pad was damaged, but by desoldering from it, the ripping of the batch did not go.

Each time BKwriter immediately after connecting the WBL5C power supply spits out the error:
Flash ID:0x00000000
Time:2.827s
Speed of Programm:115200bps
erasing flash:0x00011000...FAILED

I also installed everything for ripping/uploading via python, but even the ripping wouldn't start there.

Show where you get 3.3V, put a 100nF capacitor after the LDO regulator, make sure you reset by cutting off VDD between the module itself and the 3.3V regulator output (and if so, try to cut off together with the entire 3.3V regulator), change the USB to UART converter to another one, change to other baudrate...

Sometimes a slightly higher baud may work and a lower one may not. E.g. 921600 might work.

I reset for LDO.
I gave a 10nF capacitor (because I had no other) for the LDO.
This capacitor and changed to baudrate 921600 helped! Thx
I have always been taught by experience that it is better to program at lower speeds and I did not think that higher speeds might be required here :)

Accidentally, through many attempts, the RX pad from the PCB fell off, but I managed to stick a pin in the tin connecting the chip with the PCB

Hello @marioalmeida, it's nice to see you after so long time! OBK is now much more stable, it's good you're updating devices.

Regarding your question, see a screenshot from our FAQ:

BTW, Windows port with a working scripting demo will be soon released! You will be able to quickly develop and test OBK advanced scripting on Windows machine, without even having an IoT device!

Hello p.kaczmarek2, yes after long time. After the issue of BK7231N hanging where I had to toggle the circuit breaker, I gave up on all the BK7231 T/N devices, now thought to revisit and started to upgrade to the latest firmware but ended up with duplicate mac address, I am not sure how the TLV header of RF partition was overwritten as I just upgraded from 1.12.54 to 1.15.x
After executing "Restore RF Config (T and N, not fully tested, dont click)" button and then reboot, I was able to change the mac address

@marioalmeida we are sorry that you experienced that issue with early version of OBK. We had a MQTT issue that was appearing in a certain usage scenario, it should be now fixed. I am testing dozens of devices daily and they are stable:

Our team has resolved this issue already. If anything else bad happens, please report.

PS: "startDriver SSDP" , I recommend putting that in startup. Devices will show up in Network Devices then.

Your support is very valuable, we need users and testers in order to improve the firmware.

@p.kaczmarek2 Very nice, I'll find some device to try out as most of the N modules are replaced with T

What is the use case of this? autoexec, firmware upgrade?

In this new version I have seen 2 mqtt topics energycounter and energycounter_last_hour, is this Wh, KWh ? or something else?

Now both T and N are stable, the only thing that is missing is a power saving mode, but we have a proof of concept working, so stay tuned.

SSDP? It lists all devices in Windows Network devices section and when you open a device, it leads you to its web page. Very handy.

I think it's Wh. You need to run NTP for that. This was mostly added by our contributor @valeklubomir who also did a great fixes for MQTT stability. We will add more documentation later.

@p.kaczmarek2 , is it possible to add these mqtt topics to HA auto discovery?
rssi, uptime, freeheap and mac but entity_category must be diagnostic

@marioalmeida if Home Assistant Discovery protocol supports that kind of values, there is no problem. I can look into it if you want, but it might be faster to ask our contributor @iprak who wrote the HA discovery support for OBK.

@p.kaczmarek2 , yes that is possible, check this image which is configured with manual MQTT.

@iprak, appreciate if you can add that as I can avoid to configure it manually.

@p.kaczmarek2
With my scheduled router reboot (close to 5 am daily)
I noticed my N device took longer to reconnect while T reconnects instantly.
Is there a timer event if wifi offline I can use to trigger restart with the script?

Hi, I was able to flash OpenBK on a Tuya light bulb with cloud cutter using the generic driver. The maker is Antela (best seller light bulb in Italy on Amazon). Link
The device work and I can access it's configuration page. The problem is no matter what I try, it doesn't turn on. I've tried lots of PWM roles but it hasn't lit up even once.
I'm a total beginner and I don't know how to solder. Anyway, I destroyed one of my bulb to see the PCB and chip but I'm lost. The only thing I'm sure is that it's a BK7231N module and that it use C2BL. Any help?
Thanks in advance

EDIT:
Ok, after a lot of reading I think I'm almost there.
Pretty much the same configuration as Daybetter 800 Lumens 120V 9W RGB+2700-6500K bulbs (BK7231N/CB2L/BP5758D) found in the wiki. Now I don't know if I need to remap channels...
Anyway leaving this here in case anyone has a problem with this particular bulb.
Really <3 for the project. Thanks!

Thank you for your huge contribution to the development of the software and its continuous development.
I have three power metering sockets based on W600 and BL0937 purchased three years ago.
So far, I've used them with a replaced module for esp8266.
Recently I found the OpenBK7231T project page and decided to go back to the W600 TW-02 V2.0 module.
I managed to replace the firmware and connect to the wifi network.
OTA updates and integration with Home Assistant work without problems.
I configured the pins and the button and relay work, but there are no readings from BL0937.
I tried to load the BL0937 driver via Command Tool but I get the error: Error:CMD:cmd startDriver NOT found (args BL0937)
What can I do to enable BL0937 support?
Also, remembering the last state of the butcher doesn't work.
If I enter 1, it is on after startup, and if I enter -1, it is always off.
Is it possible to configure it so that the relay does not turn off for a second after restarting (esp8266 does not have this effect).

If the red, green, blue colors doesn't match when you're choosing the colors (eg red is green or green is blue) then you'd need to remap the channels

I'd recommend using tuya-cloudcutterso you avoid can soldering and flash the firmware via ota, pretty useful when you have a dozen or more bulbs without having to teardown each one

@ferguson88 I didn't know about LSPA on the W600 beforehand. This is useful information. BL0937 is not compiled there. I can add them to the build and try to run them, can you help with testing if needed?

I'll try to fix the things you mentioned. I need to find where my W600 dev board is...

I will also ask @iprak what time he has.
