Daly Smart BMS - odd behavior

[DiySolarU]

But before that it worked in your app? What did you do? There is no reset and also firmware is not downloadable. You have to contact Daly support to get a newer firmware, but it is hard to get it from Daly....

Happy New Year, everyone!
I had a (slight) problem with my 4s 250A Daly BMS (reading 2A off currents and cell1 voltage 250mV too low). I updated the firmware with PCMaster after reading that that helped for someone. Now I have a bigger problem getting an "EEPROM storage failure" and I cannot read any values any more. Only the stored parameters are readable.

I am using the software recommended here for the same hardware version.
Does anyone have a clue what to do?

@haluec

Maybe you tried to load the wrong firmeware. Daly 4S is not the same hardware as Daly 8/16S. You need to contact Daly support to get the latest firmware for the 4S and try to load the firmware.

After a series of mails, Daly now sent me firmware for the 4s boards in .hex format, which only works with the sinowealth software. But my board only connects with PCMaster. Any ideas? :-(

Lev-1 must always be a less aggressive value than Lev-2

Look at my setting above.

You also need to set the SOC level here to 25 and click Set

Thanks for this! I know this thread is old but this page is different than the Read Param page and I didn't notice this setting. Thank you thank you!
