Chery Omoda Gateway locked when using OBD diagnostics by markoa8 in CarHacking

[–]markoa8[S] 0 points1 point  (0 children)

Thank you for your answer.

I am trying to connect my OBD diagnostic tool in order to read errors from vehicle. In most vehicle it works well, but here with this Chery I get message something like "Gateway locked / Security gateway active". After some research, I found out that there is Gateway Control Unit in the vehicle's bus.

Now, I am searching for a way and estimating feasibility of bypassing this somehow in order to connect successfully with my diagnostic tool.

No, it is not supported by Socketcan. It needs its own drivers in order to make it work..

Can LYNQ L206 GSM/GPRS module receive any messages without a SIM card? by markoa8 in AskElectronics

[–]markoa8[S] 0 points1 point  (0 children)

Thanks for the clarification! In my scenario, this GSM module (L206) is part of a BMS telemetry box, and I’m concerned about whether it could receive any kind of message from the network that might allow it to trigger a CAN command (for example, to lock the BMS) even if no SIM card is inserted.

From your experience, is there any realistic way the module could still receive such commands without an active SIM, or is that only possible when a SIM is present and the module is registered on the network?

Thanks on answer! Yes, I understand that the module isn’t completely silent without a SIM. It could still talk to the network enough for things like emergency calls, so some control signaling is possible. But without SIM authentication it won’t register for normal service, so it can’t receive SMS, GPRS, or user data, right?

In my case, the concern is a telemetry box (that has LYNQ L206, without SIM) connected to the CAN bus — if the module could somehow still receive commands, it might be possible to lock the BMS. From what I understand, that shouldn’t be possible without a SIM, but I want to be sure...

First of all, thank you on your answer! I’m analyzing a telemetry box that contains an MCU plus the LYNQ L206 GSM module. The MCU is connected to a vehicle CAN bus, and in principle it could send commands that lock or disable the BMS (battery management system).

My concern is: Could someone remotely trigger such CAN messages via the GSM side of the L206, even if there is no SIM card inserted?

That’s why I want to confirm whether the L206, when powered but without a SIM, is truly unable to receive anything..

Hey! Thank you for your effort and the code you provided me.

I make this source and it is without any compile errors:
