Good luck! ?OK, thanks. The HW is different to mine, but I will try the next days over the APP beginning with your version and so on...
I'll post the result...
MONITOR/USB Kabel funktioniert NUR am 3 poligen MONITOR Port am BMS (NUR mit "Sinowealth" Software).Danke, aber funktioniert das UART-Kabel an BMS mit der Monitor-Buchse?
Richtig.Thanks a lot...
Also bei Verwendung von PC-Master BT-Dongle gegen UART-Kabel tauschen, richtig?
Mit RS485 Kabel (USB/RS485) am PC Master (und BT Dongle in UART an BMS), aber NUR, wenn RS485 Port am BMS aktiviert ist (Sonderoption beim Kauf).Eine Möglichkeit zur dauerhaften Verwendung von BT und PC-Master habe ich dann an meinem BMS nicht, oder?
OMG! You made my day!
Jetzt kommt Kabel Nr. 3 ins Spiel. Ich glaub diese Option schenk ich mir - weiß gar nicht ob der RS485 aktiv ist...
Nein, die Aktivierung bestellt man normalerweise bei BMS Kauf (als Option). Vielleicht gibt Geräte die sind mit RS485 vom Werk geliefert (das macht z.B. HiBMS, Daly Baugleich). Einzige sichere Möglichkeit ist, das USB/RS485 Kabel am BMS ausprobieren.Bedeutet das jetzt daß, wenn die Ports da sind, diese auch aktiv sind? Oder können die vorhanden und nicht belegt oder freigeschaltet sein?
I'm having the same issue after a failed update with iPhone. Connected to the USB and not getting any readings from PCMaster. I have an identical Daly BMS (LifePO4, 150A, 4S) and I get readings with that one right away. I think I bricked my BMS with the firmware update.Hi! It is my 1st time here. I bought recently a Daly BMS 3S 12V 250A with fan for a Li-Ion 400Ah battery installed in a motorhome, which I received and installed during early december and it worked well until 24 december, after this unsuccess firmware upgrade. I received a message to upgrade the firmware and I followed the instructions, which has been a huge mistake. The battery was running with PV charging and equipments were connected. Everything were working well. I tried to complet several times but always was given an error related with the code. After, I reinstall the app but it was given the same error. After that, I tried several things, such restart the BMS disconnecting B- and balance wires. After that, the BMS simply don't get activated and Bluetooth not working anymore. I read a lot of good information available here and tried almost everything to activate the BMS unfortunately without any success. Actually I read around 2.8v between P- and B+ and around 11,8v between B- and B+ without any charge/discharge connections. If I connect some equipment to the battery, it will work but if I disconnect the equipament it will goes under sleep. The BMS does not accept any charge thought B+ and P-, only discharge. I connected the BMS with PC Master Software and Sinowealth through RS485 but I don’t have any readings. Is it possible that I lost the firmware? I read here in a manual that the CAN communication wakes up the BMS when under-voltage fault of the BMS occurs. Is it true? Any help that you give will be very appreciated! Thank you all!
AliExpress chat. Via a rebrander company. So it was a Daly, but I didn't actually deal with Daly.@Martijn , how did you get their customer support?
I have sent several requests at daly@dalyelec.com with no luck .
