    Ok I did a short tutorial on IR for BK7238 (or any supported platform, in general):

    regarding submitted template, I think P26 would be better as WifiLED instead of LED and P9 as BtnScriptOnly (and some scripted use) instead of dInput

    Added after 33 [minutes]:

    OTA is not successful if you keep Tuya bootloader. I think users need to be aware they might need to overwrite bootloader. or a variant is released that caters for Tuya download partition, if standard (not looked).

    It's also not obvious how users can choose a variant solely from Easy Flasher. They would need to know to go to second releases list and to copy file to \firmwares folder in EF first.

    In IrRemoteESP, the IR driver is IRRemoteESP. In original OBK, IR driver is Arduino-IRRemote.

    IR2 driver is just a little experiment I made with @DeDaMrAz and it was presented in my IR tutorial:
    https://www.elektroda.com/rtvforum/topic4062643.html
    https://www.elektroda.com/rtvforum/topic4063469.html

    Why original bootloader is not working with our OTA RBL? So.... we probably can just add "T1" option to flasher and then silently enable bootloader overwrite?

    unsure yet. OpenBK7238 does OTA to 132000. Can't yet see obvious rbl header or 01PE partition information in pain-text in bootloader in factory dump.

    OTA fail with factory BL was same with Tuya soil tester with T1

    Quote:
    OpenBK7238 flashed over the top of factory firmware. I chose to overwrite the bootloader because keeping the factory BL meant OTA updates were not successful.

    @p.kaczmarek2 I have bought a new deivce, IHSENO TY_WIFI_TEMP_V1 wifi controlled temperature and humidity sensor. It had a T1-3S. I have attached photos of the board and the unknown microcontroller.

    I had to desolder the T1-3S from the board to flash it with OpenBeken - the TX1/RX1 ports are used by the microcontroller. It is now visible in Home Assistant via MQTT. Annoyingly, this device automatically turns on for 15 seconds and then turns off - so you have to work quickly when configuring, unless you desolder again! This is controlled at the base microcontroller level. Pressing the reset button can force it to start.

    Can anyone help me to try and get the temperature/humidity data from the UART stream from the microcontroller (coming into the T1-3S on pin 15 and 16 (which correspond to P10 and P11 on the IC). What I select in the OpenBeken device config page?

    that's a TuyaMCU device so you'll not be setting assignments in the config page but rather running the TuyaMCU driver and setting up dpIDs relevant to your device

    Hi there,

    Thanks for clarifying the device is TuyaMCU - I didn't even know this existed! I have attached the backup.

    I have attempted to work out the dpID list as described here Link.html but this doesn't really work. The only tuyaMCU information I receive after issuing the tuyaMcu_sendQueryState is this:


    Info:TuyaMCU:Consumed 7 unwanted non-header byte in Tuya MCU buffer
    Info:TuyaMCU:Skipped data (part) EC EC EC EC EC EC EC


    The basic firmware is extremely annoying - by the time the device starts, connects to wifi and mqtt, you only have about five seconds before it turns off!!! I wish I could disable this annoyance.

    how are you powering the device at the moment? I tend to solder direct to Tuya module GND/VCC so the TuyaMCU can't cut power (I think they usually cut ground)

    So you would solder jumper wires from the gnd and 3.3v pins on the MCU and power it that way?

    I'm powering it from the inbuilt battery supply, two AAA so 3.3V.

    tuyaMcu_setBaudRate 115200
    tuyaMcu_defWiFiState 4
    tuyaMcu_sendQueryState

    However, when I send the tuya_Mcy_sendQueryState, I get no response. I also have another browser tab with http://192.168.20.189/cm?cmnd=DP open, when I refresh this window, I get a Error:CMD:cmd DP NOT found (args ) return in the log.

    Ok, quick correction - tmSensor is required along with TuyaMCU for battery powered devices, but tuyaMcu_sendQueryState is not supported there. TuyaMCU battery powered devices are hard to work with and they don't allow state query, you have to follow their protocol exactly and they only send data if you do it as expected.

    It may be a good hint to keep channels used for TuyaMCU battery powered data persistent (-1 startup value) or make sure to publish their values after they are sent by MCU, to avoid sending zeroes.

    Adding startDriver tmsensor, I cannot see any tuyaMCU data being displayed.

    How does one find out what the 'protocol' used is? I have no idea what channels are in use, to set that -1 flag, or how to publish the values after they sent to the MCU.

    Is this something to put into the 'too hard' box (i.e. the bin?) xD

    There is no such command for battery powered devices and there is no place for that, protocol is strict.

    Battery powered TuyaMCU devices will never work correctly if you power Wi-Fi module externally.
    Read whole topic:
    https://www.elektroda.com/rtvforum/topic3975583.html
    Documentation fragment showing TuyaMCU Wi-Fi and MCU communication sequence
    As you can see in the image above, the OBK has to boot exactly after MCU turns on it power, and then tmSensor must send a packet. If you have OBK booted at different time (powered externally), it will now know when to send first packet, so transaction will not start.


    Garbage data can happen if you power Wi-Fi module externally.

    And in that state if you press the button on the device couple of times are there any changes in the log?

    Also set flags 37 and 51 and lower the "uptime in secondes..." on the bottom of the flags page to 3.

Topic summary

The discussion concerns the Tuya WiFi IR universal remote control module T1-3S and its compatibility with OpenBeken firmware. The user attempts to identify the chip and read UART logs via TX2/RX2 pins, encountering boot messages and errors indicating possible connection or user errors rather than firmware incompatibility. Respondents suggest using OpenBeken Easy Flasher in BK7238 mode, emphasizing correct wiring, power supply considerations (not powering the WiFi module solely from USB-UART 3.3V line), and using TX1/RX1 UART pins for user data instead of TX2/RX2, which are reserved for log output. Shortening cables and ensuring common ground among USB-TTL converter, power supply, and module are recommended. Despite multiple attempts and power cycling, module readout fails, likely due to connection issues rather than lack of OpenBeken support. The chip is identified as BK7238, and the module requires proper UART interface and power setup for successful flashing or communication.
