Add support to "Set type of VVDI wireless remote" #16

Open pispo1 opened 1 year ago

pispo1 commented 1 year ago

In the current version it is supported setting the type of the SuperChip transponder (e.g. ID7946 type). Setting the type of the transponder does not set the type of the wireless remote.

Without this feature, when it is programmed a SuperChip remote (e.g. XEMQB1EN), the transponder works but the remote not. Indeed, in the Xhorse app, there is a "Special function" called "Set type of VVDI wireless remote" that supports such functionality.

Please capture the communication between PCF7991 Base-Station IC and µC while using the "Set type of VVDI wireless remove" function. Only when this is provided to us, we can implement the same in hitager.

I personally do not have such tool, thus I do not have the chance to figure out how it is done.

Thanks @tusker-tools for your proposal. I have proxmark (sniffing) but do not have any VVDI programming tool. Is there anyone (e.g. @kivijakola) that can sniff such communication between SuperChip remote and SuperChip Tool key?

I did some sniffing couple of years ago but unfortunately there was huge difficulties with remote programming. Data amount was very big and crypted. I couldn't identify any parameters from transfered data. Maybe there was whole uC firmware trasnfered. Then didn't put very much effort for this.

I tried to find captures but unfortunately I have not archived them.
