and while we are on the subject, can anyone explain to me why that eNBT adapter costs so much ? It is only simple microcontroller with 2 can transciveres, 1 uart used and few digital IO pins...

This is the big problem of retrofiting in E series emulator costs from 30 to 40% of cost of retrofit

Yeah i agree, lets see how much interest we will get on the idea so we make it happen, im thinking about three base options for now:

1) arduino atmega328 + 2xMCP2515
2) arduino sam3x
3) stm32f

latter two are 32bit MCUs and have internal 2x CAN interfaces, so only transcievers and dc-dc converter would be needed additionally, on first option we have simple atmega328 which is 8bit and would need 2x interface + transciever so MCP2515 module would fit perfectly and dc-dc converter also. But i think for all three options even in single peace orders it would not exceed $20

and since im thinking about this, one more thing came up my mind who can help us on this, so ill talk to the doctor(Gini) tomorrow to see how he stands on this. he can make a gui and we can make then fully open source CAN device which can be anything: can gateway, can bridge, can filter, can emulator, enbt emulator etc.

The price charged for a product are factors of the actual HW involved, what the market will bear and what it cost in time to develop. I can image that to map all the messages from E series to F series took a fair amount of time with trial and error - if there was a document, if would be easy but it isn't that simple.

It does seem expensive but to duplicate from scratch would be a significant effort.

Can messages are almost the same, it is mainly different baud rate 100k->500k and they are all well documented, its just not public, same as all of these devices schematics and everything else.

I think the whole thing in the bootloader, you need to change it.
Remake the same combox from the f-series in the e-series!

The hardware emulator sounds like an excellent idea, I think an affordable solution would be wildly popular. The existing emulator costs as much as the NBT hardware itself.

[intel123]

Well just a little update, and we will probably make a separate thread on this, so i had talked to Dr Gini and he agreed to join on the project, i also had other members which can contribute with their knowledge and work to make all this go as fast as possible. Goal would be a device that can be All-In-One:

1) CAN GATEWAY/WAKE-UP DEVICE for PC or Standalone:
- connected to computer with windows GUI to send receive or monitor CAN messages.
- standalone mode: to send CAN wakeup messages for bench testing devices.
---------------------------------------------------------------------------------------------------------------
we can make it work on any baud rate, standard or protocol so it can be used for all devices, with it you would not need a CAS or ZGW to wakeup devices (for devices like ones that need MOST interface to wakeup, we would supply .prg files to switch wakeup mode to CAN), or in worst case scenario you can add ZGW to your bench and remove CAS etc.

2) standalone eNBT adapter - adapter which will translate 100k CAN into 500k CAN and add what is missing for NBT wakeup so it can be used in E series (like 0x12F etc.) (also so we are not behind others, we would have a complete programming GUI for NBT on Windows)

3) CAN filter/emulator of any kind in any car: pass thru can communication from interface 1 to interface 2 with modifications of messages or inserting message for connectivity, retrofits, message blocking, etc. This way you can retrofit anything in anything, filter and change VIN, ISN, MILAGE or whatever on the fly which will enable you normal function of devices that cannot be adopted to the car for some reason.

these are current ideas and the goal is to make it OpenSource project software-wise, hardware would be also based on opensource as we would publish all schematics with the firmware sources and tehnical documentation. Based on Arduino or STM32 MCU it cost should be =>20$

So, You think that can be possible to get for example combox/ulf from F series and simply program it by WinKFP in E series ? (both has the same part no).
Have you done something like this before?

Part numbers for these devices or types are not the same i dont know where is your info coming from but in general:

E series = BN2000
F series = BN2020

as device exists for both series there is no reason to research such thing.
