Tuya WiFi IR T1-3S - does the module support OpenBeken? UART logs, chip identification

Question

I purchased the Tuya WiFi IR universal remote control . Upon opening the device, I encountered this measure . . T1-3S module. I don't know if it is supported by OpenBeken. I found documentation of the module , and link to Chip . When connected to TX2 and RX2 something like this appears in the...

Is OpenBeken Easy Flasher able to read it's flash?

divadiow · Answer

Surely. BK7238 mode. CEN or power-cycle 3.3v to start,

Nargo · Answer

Something like this: .

p.kaczmarek2 · Answer

This is more like user error. Something happened that the USB to UART converter was disconnected or overloaded. How do you connect it?

Nargo · Answer

I unplug the power supply .

divadiow · Answer

EF v49 does work OK dumping BK7238

Added after 1 [minutes]:

your com port is already open in another app?

I get this if mine is.

Added after 54 [seconds]:

are you getting the windows eject sound? are you connecting USB-TTL, 3.3V PSU and module grounds together? what does your wiring look like?

p.kaczmarek2 · Answer

And the power supply by feeding 5V to the LDO input on the board? Or by feeding 3.3V from the USB to UART converter to the 3.3V of the WIFi module? The USB to UART converter does not have enough current capacity to power the WIFi module. And shorten the wires. Try in BK7238 mode.

Nargo · Answer

In either case it is not possible to do a module readout. All modes tested.

divadiow · Answer

it looks like you are connected to TX2/RX2, not TX1/RX1 Code: TextLog in, to see the code .

Nargo · Answer

Nothing appears on tx1/rx1. But will try it tomorrow.

p.kaczmarek2 · Answer

I can't remember anymore, did you flash a regular BK7231? Same here. At this point it looks like OpenBeken for BK7238 (not BK7231) should work for you. But shorten the cables. The fact that it throws away the UART port is a connection or user error , not a compatibility issue.

Nargo · Answer

Enclosed is what it reads from UART1

What was wrong?

Your batch runs on my BK7238:

From this it appears that OpenBeken is working on your device. Can you give me (I'll use for the tutorial) an accurate and clearer picture of this module and information where the device came from, pictures of the case, any info you have?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Helpful post? Buy me a coffee.

I will send everything in the evening. Flashować OpenBK7238_QIO_1.18.140?

That's what I'm thinking, first on a trial basis with overwrite bootloader disabled, and if it doesn't start then with overwrite enabled

Writing sector 0xD4000... Writing sector 868352 failed!
Writing file data to chip failed.

Writing sector 0xDA000... Writing sector 892928 failed!
Writing file data to chip failed.

Writing sector 0xD6000... Writing sector 876544 failed!
Writing file data to chip failed.

Same every time.

When I try to restore the backup it also gives me errors.

In a random location? Then try a different baud.

Nargo · Answer

Sprawdzane 115200,230400,921600,1500000. Overwrite on/off too.

Another usb to uart converter? shorter cables? Or is TX1/RX1 being used for something on this board and interfering with something?

Nargo · Answer

Another converter:

Serial port open exception: System.IO.IOException: The device attached to the computer is not working.

w System.IO.Ports.InternalResources.WinIOError(Int32 errorCode, String str)
w System.IO.Ports.SerialStream.InitializeDCB(Int32 baudRate, Parity parity, Int32 dataBits, StopBits stopBits, Boolean discardNull)
w System.IO.Ports.SerialStream..ctor(String portName, Int32 baudRate, Parity parity, Int32 dataBits, StopBits stopBits, Int32 readTimeout, Int32 writeTimeout, Handshake handshake, Boolean dtrEnable, Boolean rtsEnable, Boolean discardNull, Byte parityReplace)
in System.IO.Ports.SerialPort.Open()
in BK7231Flasher.BK7231Flasher.openPort()
Failed to open serial port!

Will try from the laptop tonight.

Tuya WiFi IR T1-3S - does the module support OpenBeken? UART logs, chip identification
