Trying to read data from a 4s daly bms using uart usb cable that was included with a 16s deligreen bms.

Is the pin out different between 16s bms and 4s bms?

Im trying to connect to correct chipset. As you can see on pics port connection is ok but no data is retrieved.

Tried both 6 pins ports but none works for uart. Bluetooth works on one of the 6boin ports just fine

There are 2 different softwares to use with Daly BMS.
User shall verify what port they have on their unit and type of BMS.
Daly has multiple version and each software has differnt module support.
See list on https://www.dalyelec.com/newsshow.php?cid=25&id=77&lang=1

USB-UART
(4 pin cable) shall use BMSMonitor V1.2.8 latest (other versions V1.1.x exist as well)
I noticed that older version had multiple board support, where V1.2.8 looks like a single board version.
It offer config for multi cell BMS up to 48S

USB-Monitor
(3 pin cable) works with BMS tool V0.1 or V0.2
Support bms (3s to 10s) as seen from presentation panel.
