Thank you, please try following configuration:- relay on P24- button on P6- WiFi LED n on P11Tell me if it's working for you.

Shorting CEN to ground really should help. I know because I have made those two boards (replaced ESP with WB3S and CB3S):

The RST button resets them by shorting CEN to ground and then I can flash them. But maybe your circuit is different.

Don't worry about the language. We are here to help. Please submit any other IoT devices that you have. We can help with configuration, or you can just post your configuration to help us.
We are making a list:

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600 and soon supporting RTL and W701:

Hello, do you have a multimeter? You will need to check where the traces are going, use the continuity test mode, the one with "beep".

Or do you maybe happen to have original firmware backup, full 2MB?

bozer1978 · Answer

Yes, there is a full backup, how can I disassemble it?

Yes it works, thank you very much. Please add support to the next firmware. BK7231T There are also two keyboard players. I can add a little later.

Much better, but please use syntax json tag next time. It makes post more readable.

bozer1978 · Answer

The only caveat, for firmware, power is required to be supplied for two nickels near the button. When soldered to the module, it cannot reboot into firmware mode. On the board, some kind of capacitor does not have time to discharge.

p.kaczmarek2 · Answer

It's also worth to save the device picture: But you have already flashed, right? If you have capacitor that prevents fast reboot, you can use CEN to reboot. Short CEN to ground for 0.25s

bozer1978 · Answer

CEN not help. Only connecting a separate power supply and breaking. He himself fought half the evening until he connected to these two heels ...

I am writing through google translator... There may be errors.

bozer1978 · Answer

It didn't help... I tried it in different ways... I'll try to flash two keyboardists today. Although I have repairs in the apartment and problems with time.

p.kaczmarek2 · Answer

Can you show the photos of those two devices that you are going to flash? There is no need to hurry, I can help you when you have time.

bozer1978 · Answer

In general, here is the data on the two-key. He seems to have died. Since I could remove the backup from it, I post it. When clearing the memory, the contact went away. Now I can't connect it. No combinations will go into firmware mode.

P.S. Soldered the wires. The effect is the same.No response from the chip.

bozer1978 · Answer

This Lonsonho Tuya X802A-L has (no neutral).. While I can not run the firmware on it ...

p.kaczmarek2 · Answer

I will forward the binary for analysis and post the details here later today.

How have you managed to lose the contact with the device? Can you check does it boot up? Connect USB to TTL RX to TXD2 pin of WB3S , set baud 115200 and check can you receive log?

bozer1978 · Answer

Hello, since I supplied power to the patch by closing and opening the contact. Then most likely when my wire got in the wrong place, then the power went on the ground, with all of this consequences. I removed the module with a soldering station. I soldered contacts to it, it is not recognized. Throw off the file, please, I will try to bring it back to life ... I have already flashed three single-key modules, they are perfectly sewn onto your firmware.

p.kaczmarek2 · Answer

Here is a template for Lonsonho Tuya X802A-L has (no neutral) BK7231T - 2gang:
- P1 - Button - Channel 1
- P10 - Button - Channel 2
- P14 - LED - Channel 1
- P26 - LED - Channel 2
- P9 - Relay - Channel 1
- P8 - Relay - Channel 2

bozer1978 · Answer

It turned out to flash the module ... It is recognized and quite normally appeared on the network. Began to set up, please explain how to assign channels? Pressing any of the buttons opens L1.

p.kaczmarek2 · Answer

You can assign channels in Config->Configure module.

bozer1978 · Answer

Here in the ( pin. setting: ) ?I tried, but the device completely stops responding to pressing.

p.kaczmarek2 · Answer

I will check this, but you can also do it outside web app , in the native HTTP interface...
