Hi! I've just had exactly the same issue. Ordered some 4S 80A smart BMS. Their bluetooth module and app work, but I can't set any parameters. I also can't communicate with their BMS using the UART cable they sent me and the app posted here - https://diysolarforum.com/resources/daly-smart-bms-pc-software.50/
@Richard888 would it be possible for you upload the software somewhere? I haven't had anything back from Daly support, I suspect it's my gmail address causing issues.
