Today's Daly SmartBMS Android App Update forces a firmware update which fails

Hello,
How did you manage to flash with an iPhone? If you can direct me to any info, that would be great .
Since the last IOS update, smart BMS App doesn't work for me. It seems I can connect to my 2 Daly 4s 250A, but no info is displayed .
thanks

I have exactly the same issue, so it’s not just you. I can’t be sure but it might be since I updated to iOS 16.2.

I came to this thread to see if there’s a solution, but I tend to think that when an iOS update breaks an app, it’s normally just a matter of time until there’s an app update which fixes it, so if I need to just wait a while I can survive without bluetooth remote telemetry from my Daly. Especially this time of year.

They were both green and turn grey when I switch them. The inverter beeps to show absence of battery when I turn the Dischg indicator off. The inverter inverts properly too.

When set to volts instead of %, the inverter shows variable volts as it attempts and fails to charge the battery but uses the battery power and/or solar/pv to power loads. When the BMS is bypassed, the inverter charges with no trouble.

Today I experienced the inverse of your experience. I've not used the battery for a few days but needed it to power a 240V appliance this afternoon. The BMS turned on when I pressed the button on the BT module. Charge and Discharge showed green on the App main display. However the Inverter reported only 8V. I needed to apply a 12V charge across the BMS (Battery +ve to BMS -B) to get it power up and supply juice to the inverter.

Seems to be a firmware flaw which I can handle while I'm at home but will be useless when I'm camping in the summer. I guess I'll be changing Daly for JK after all. :mad:
 
That is the wisest option! I have already ordered JK BMS to replace my 2 Daly that will end up in the dump.
Hopefully, newcomers will get the right info here and avoid any Daly product.
I don't even imagine how it is possible, such a mess. Those people don't even test anything before publishing an update.
I'm not on Android , but on iOS. Not the same issue, but the App doesn't work since the last update .
I'm touring in the mountain, so I will need to go back down because of these clowns

I am getting a JBD instead. I don't have a 48+V charger to test. And since the inverter sees the complete battery volts, inverts but doesn't charge, I think ordering a separate charger would be of no use for now.

sure, It's with the phone of a collegue. It's version 2.0.15 if I remember well of the smart BMS for I phone App. i have a 17S bms so I enter the code 727825 (look above to see relation between code provided and firmware version ). the upload went a bit faster than on android but moreover it end well and the fw was well flashed. unfortunately I haven't manage to have a fully working bms yet. com can for example is not working , which was before the upgrade. I think best is to try and if doesn't work, wait for the proper firmware to come after cny. Be carefull all. the 3.3V tht power the ble failed. I have connected the ble power to my first lifepo4 cell. hoppefuly, the 3.3 ble and independant from the mcu voltage. that mean the bms is still in good health ( but you have no more ble power buit in ).
 
I got feedback from daly. Daly will not support us direct.
Only the direct buyers.

No Firmware Versions, no Support, no Informations!

It's a sham.

I'm still running on iOS 15.7. I haven't updated to 16.x . Things stop to work when I updated smart-Bms to 2.0.1.
So not related to iOS.
I have found this other thread , maybe a solution for us too :

Daly BMS connected Bluetooth but no data

Hi all. My Daly 250 BMS has been working fine for 2 years (and still is working fine I think). But now when I connect to the Bluetooth it connects but I get a screen with no data. Any suggestions? First noticed it today. Last checked it all a week ago and it was fine. Trouble shooting so...

Thanks for the info and the tip, I’ll check that other thread out (y)
 
2.5.2 läuft jetzt bei mir auch
Bisher einwandfrei.
Zumindest hat man sich mit der deutsch Übersetzung Mühe gegeben...Danke an Selina!
 
I am in the process of recovering my bms after this disaster fw upgrade. I discovered one important thing on the way. the upgrade can either work or not. For some reasons, during the upgrade process the bms can loose its hardware settings ( basically the number of cells to deal with, 17S for me ). If that happen . when connecting in uart or with the ble app, the interface will show an epprom error. If you have that error, your bms has lost its initial parameters and will not recover with firmwares available here at the moment. Daly will reconfigure a fw for me that will reset those parameters and the bms will start again for sure. I am now waiting for this firmware. If after an upgrade you have many errors showing and an eprrom error code, you have to contact daly to get the good custom firmware. As soon as I have my 17S / 500A F103 fw, I will post it here

Not sure which security code to use to update this version. Just 123456 or one of the other firmware related codes named in this topic. Using android app version 2.5.2
Software version. 20210729-1002A
Daly 4s 150A 12V

If your BMS has not stopped and you have sensible values in a working App, DO NOT update the firmware!

It was the firmware update which screwed all of us. Just resist the temptation!

The 123456 password is only for changing App parameters and is not the firmware password.

If you truly, desperately want to update your firmware then you MUST contact the vendor where you obtained your BMS and ask them to obtain the firmware code from Daly for you.

Good luck!
 
My problems are quite random. The system bounces between 2 and 13V for some time. I have to disconnect the power to regain power in my RV.
I first thought there was a connection with the temp sensor/ntc. But I could be very well the BMS firmware. I do not see any changes listed so it's a shot in the dark indeed .
But I am willing to take the plunge.
Not sure if my seller is any good in security codes for firmware.
 
Today I got a new firmware from Daly. It seems to solve the current problem. May someone else tested it? It is only for Hardware St103-309 and named Inverter Basic Version.

Could this firmware be good for this?

7s 24v 150A BMS R32U-HE18
BMS SW version: 11_220415_100B
BMS HD version: BMS-ST103-309E

Thanks

I had this issue and now it is resolved.
First of all if your BMS seems to not boot anymore. don't worry connect it to the PCS (still you will not see the battery stats) its normal.

1- try different firmware. i had to try like 4 different firmware from Daly before it was successfully updated/upgraded.
2-dont worry about the Firmware code. that's going to be displayed if you connect your BMS via Bluetooth while it failed the firmware upgrade/update.
3- be patient. even Daly support seemed they didn't know what they were asking sometimes.

even though my BMS works now i have replaced it to JBD.

good luck
 
It turned out to restore the BMS, after an unsuccessful firmware for 24s. Thank you! BmsSTM32F030_309_20220722.s19

Can you clarify what you mean by

"First of all if your BMS seems to not boot anymore. don't worry connect it to the PCS (still you will not see the battery stats) its normal."

I have a Daly 8S laying around which was bricked by a firmware upgrade. Can it be revived (without attaching it to 8 cells?)?
