Hi everybdy !

I'm trying to access MBB logs with an OBD-II link with Gen3 (Zero S 2024/2025).
But it always answer : "log printing not supported".
All others cmd of help are working well.
Do someone know how to do ?

with help cmd :

-- MBB Event Log Management --
  elddh           - Log Dump by Date dump hex.  Usage: elddh [start date: MM DD YYYY HH MM SS]
  eldh             - Display event log contents in hex for export to .hex (need log decoder to decode)

My tests :

ZERO MBB> elddh

Enter an end time (MM DD YYYY HH MIN SEC)
02 16 2025 00 00 00 (entered)
log printing not supported

ZERO MBB> elddh 02 16 2025 00 00 00 > 02 17 2025 00 00 00

log printing not supported

ZERO MBB> eldh

******************************************************************
Current MBB time is Mon, 02/17/2025 09:46:21
VIN: PAG...,                     Serial: R...,  Model: S_A1,   MY: 2025
Board Name: MBB PDU POTTED GEN 3 STEP D1,     Board PN : 40...,     Board ID  : 05
Firmware Name : FIRMWARE MBB GEN3     , Firmware PN : 75..., Firmware Rev :37 
Build : 2024-05-28_... banka, Reset Source: Hib Wake Pin, Power-On, Supply WD, Power Val
******************************************************************
log printing not supported

Moreover, I don't arrive to access the BMS prompt : "ZERO BMS>"
I'd like to launch the "ZERO BMS> balance"

I've tried (bms login <bms> <level>) :
ZERO MBB> bms login 2 1

Logged in to BMS 2 at level none
Success

I choose <bms>=2 because "ZERO MBB> status" answers :

* * * BATTERY INFO * * *
 BMS | SOC |  Pack V  | Current | Capacity|  L cell  | H temp | L temp | Cont | Elig
 ----+-----+----------+---------+---------+----------+--------+--------+------+------+
   2   78 %  111405 mV  0 mA     137 AH    3976 mV    14 C    13 C      +     + +

What is level ? Do someone know how to access the prompt  "ZERO BMS>" ?

Thanks in advance !
