Daly Lifepo4 4s 12V 100A R05A1-HI24; no connection to pc

[Juhani]

Hi
Can someone please point out why I cant connect this BMS to pc and what am I doing wrong?
I have went through most of daly topics in this forum and still cant get it to work.
In the beginning I tried with arduino programmer and now ordered opto isolated FTDI.
Wiring is exactly the same as in this example http://blog.nicolas.cx/blog/2021/04/21/replacement-optoisolated-usb-uart-daly-smart-bms.
I just want to change dfittercur so that balancer would work with lower currents because charger is solar and 2A is hard to get in spring and autumn with 80w panel.

Hello,

i have the same problem with this Daly BMS "LifePo4 4s 100A R05A1-HK24"
I can't Connect with the original Daly USB-UART Cable with the Sinowealth BMS Tool.

BT works fine! (on UART Connector)!
The Daly BMS Monitor Tool (V1.2.8) works also, but this Tool is rubbish...in my opinion

My other BMS (4s 80A) works also with the Sinowealth Tool, but with the Daly USM-Monitor Cable
This BMS (R05A1-HK24) don't have this 3 Pin Monitor Connector.

Hope anybody has an idea!

Thank you in advance!

BR
