Can't make TYWE1S motor work

[Дмитрий Карагеур]

Hi! 

Couple of two new motors that I can't make to control.

Chip is TYWE1S flashed with tasmota 9.2.

Setup is Tuya MCU (tuya RX & TX), mappings of fnId to dpId are 11,1 -  12,101 - 13,103.

I have three motors with TYWE3S that works ok for more than a year with the same settings.

I tried to readout commands that are sent from original firmware to MCU and it differs from the one described in the "Tuya Serial Port Communication Protocols for Curtains". Even the header is not the same (original header is "55aa", here I get "55fe").

Those commands I also tried to send by console or even directly by USB-TTL to MCU and no response from the motor.

Any advises would be appreciated.

Thanks!

I can't see communication between MCU and wifi chip

Even the heartbeat has no response, though settings are pretty straight forward

If you look at the 9.2 Release Notes there are changes for TuYa so might be worth a look.

I settled what commands are being sent to MCU from TYWE1S. 

It's not a Tuya standart protocol but I have some commands that 100% work if I send them from USB-TTL to MCU directly. 

Now the problem is - i can't make TYWE1S to send anything from U1TX (pin 2). 

I have connected U1TX to USB-TTL RX, set up the same settings 9600,8,1,N. 

I use console & SendSerial5 command and just nothing comes from the TYWE1S side. 

What could I miss? Any advices...
