I don't think you're guaranteed to have `0xC1` in the message, in [these examples](https://github.com/iwanders/OBD9141/blob/ff2d79538ec177c54da349f5d06b86f6b3bfd524/src/OBD9141.cpp#L267-L274), the start is `0xc2`, but that is not anywhere in the response?

Hmm, so the request you are sending is the start communication request; [this one](https://github.com/iwanders/OBD9141/blob/ff2d79538ec177c54da349f5d06b86f6b3bfd524/src/OBD9141.cpp#L481). But then for your system it returns more bytes than the expected 6 from [here](https://github.com/iwanders/OBD9141/blob/ff2d79538ec177c54da349f5d06b86f6b3bfd524/src/OBD9141.cpp#L485) Searching...

I'm not sure I understand, the `mrfc630_cmd_load_key` function is [pretty boring](https://github.com/iwanders/MFRC630/blob/577b0433a7dfae3fe3eba7a578d784982d90be69/mfrc630.c#L140-L145), it just writes the key to the fifo and then sends a command, if you need to send another...

@chcmq , good question, I have no idea if that's even possible. You'll want to read up on how nfc actually works, if the frequency / hardware protocol is even...

Following up here from https://github.com/linux-surface/kernel/pull/144#issuecomment-1858999412 . I pulled the `feature/thermal-sensors` branch at 004898c290c9f11cd4907902773aa0cc21be9843. On surface pro 9, the following thermal sensors appear; ``` ssam_thermal-virtual-0 Adapter: Virtual device temp1: +30.8C temp2:...
