[Solved] Configuration of the Neo Coolcam NAS-MA01W mousetrap with OpenBeken and BK7231N

Neo Coolcam Mouse Trap NAS-MA01W

I have purchased a mouse trap with Tuya.
The trap is operated via a BK7231N.

I managed to flash OpenBeken.




On the right side are marked pads with RX, Tx, GND; 3.3V.

The mousetrap itself is controlled by the chip on the left-hand side. In the previous versions, the mousetrap was equipped with an ESP8266.

Does anyone have any idea how I need to configure this?
Can I read this from the tuya developer?
AI: What configuration steps have you taken so far to run the mousetrap with OpenBeken?
Tried to read config with 7231 Easy Uart Flasher, unfortunately without success.
AI: What exactly do you want to achieve with the configuration, or what specific problems are you experiencing?
Mouse catch signalling and display battery status.

Very interesting device, I haven't seen a mouse trap from Tuya before. How effective do you think it is? Let us know how you try it out.

As for changing the firmware, your device uses TuyaMCU. You should configure it according to this guide:

Although more precisely you need TuyaMCU in battery mode, i.e. TuyaMCU and tmSensor. You have the dpID in the Blakadder article:

.
You need to read about tmSensor at our forum:
https://www.elektroda.com/rtvforum/find.php?q=tmSensor
E.g. here is an example: https://www.elektroda.com/rtvforum/topic3975583.html
You can simplify it, you only have two dpID.

Can you post a 2MB copy of the batch? Remember that it may include your SSID and password if you have previously paired the device.

I tried to get a response from the TUYA Mcu with the command tuyaMcu_sendQueryState. See log extract.
I have set up autoexec.bat according to the instructions and according to the log extract it also works. I have already tried various baud rates such as 9600, 115200.




I believe the board has been heavily modified in this revision as the chip switches off after about 2 mins. The mousetrap is only switched on and connected to the Wi-Fi when a catch is made and when the battery status changes. The second chip is an ft61e0a5 from FMD which probably handles the entire mousetrap.

>>21520410 Got it working after all and Mausefalle is running.

tmsensor integrated, correct flags set.
