Daly_RS485 Failed to initialize

[jlmontes1697]

I have a raspberry py 3B with "WaveShare CAN HAT For Raspberry Pi, 2-Ch RS485 and 1-Ch CAN" (https://www.waveshare.com/rs485-can-hat-b.htm).
A Daly 7s 40A Smart BMS.
They are connected by RS485.

With the python library "python-daly-bms" I can read all the BMS parameters with the port /dev/ttySC0 but with the bms-to-inverter app I get the error: "Failed to initialize BMS"

I have the app configured:
BMS:
DALY_RS485
Id: 1
Port: /dev/ttySC0
Baudrate: 9600
Delay: 200
Inverter: HUAWEI_MODBUS (The inverter is not connected yet)
Services: HTTP

What is wrong with my configuration?
