I'm going to consolidate some of the Daly Smart BMS questions into one thread concerning initialization and parameter setting, some of it I found here in odds and ends, some I discovered on my own. First off, thanks to those who pioneered ahead of me and found ways to get these to work. I purchased a Daly 24V 8S BMS off AliExpress Daly Factory Store. Shipping was quick, less than 2 weeks. I also purchased the Bluetooth module, the LCD display, the 485 cable and the UART/USB cable. I did not purchase the Light Board. After hooking to my fully charged top balanced bank, I could not get initialization and turn on. NTC was plugged in as was LCD display. Searched here among many threads, tried shorting P- to B-, ohmmeter trick, everything short taking a hammer to it. Balance leads had been checked several times, I had it wired correctly. Tried drawing a load, didn't work either. I had full battery voltage at P- until a load was put on it, then it dropped to about 6v. I finally came across a few threads about shorting the 2 pins together on older Smart BMS's, my BMS didn't have those ports. I looked at the BMS manuals found here in Resources, some of the info applies but much doesn't. All I have is what is pictured. I had one final try, I took a piece of wire, stripped the end, spread the wires out and made a key. I took the key and dragged it across the terminals inside the Light Board port and it turned on. Success finally.
Next came setting parameters. I had already downloaded the PC version, however the Malware software I have on my laptops indicated the Daly PC software is infected with Malware and prevented any operation of the software. I tried using an old Win XP laptop I have laying around, it needs a .NET program to work. So much for that idea. I abandoned any thought of a PC hookup. Next, I tried using my Chromebook and the Android app address listed on the "manual" that came with the BMS. This has Huawei listed in the link address and can be found in the resources here. Don't waste your time, you won't get it downloaded. I decided to try my phone with BT app. I did find you can unplug the display and hook up the BT connection without disconnecting power. It would have been nice to run both at the same time, either thru split ports or a splitter. I did go to Google Play and downloaded the app here. https://play.google.com/store/apps/details?id=com.inuker.bluetooth.daliy This one works and later I downloaded it to my Chromebook and it works on it also.
I did reinstall the display and went back to parameter settings again and tried to change settings there. I wasn't successful the first time, I kept hitting Set but nothing would happen the first time. The second attempt I hit the actual reading and it then asked for the usual password of 123456. After that input your desired setting, then hit Set. Works great. Be sure when you are in parameter settings to enter Zero Current Calibration with no draw on the battery. This will help with accuracy on SOC and Ah remaining.
It's been a time consuming process figuring much of this out plus scouring various threads here. Hopefully those who have trouble with initialization and parameter setting find this thread and it helps them. In the process, I learned much about the BMS and if I need to troubleshoot it.
