xM1+ and HID multiCLASS se readers

Boo Indeed
I wanted to get the flex before potentially bricking my xM1+ on a yale doorman lock, but I guess I’ll just have to try, then see how it fairies, still keeping one original tag with me in the beginning to see how it holds up

@anon3825968 did some testing on the Yale doorman V2N with a xM1 and it didn’t work
You got a prototype M1 Flex gen1 that I could buy @amal? It ould be fun to test it, to see if it’s big enough to trigger the read

This was posted 2 weeks ago, so I am not sure of what stock they have remaining, but…

@amal

China is going through both the Chinese New Year and the Kung Flu (coronavirus)… so shipments are delayed until further notice… so we’re not listing the product until we are able to mass produce here in Seattle… however… if you want to order one now we do have some early units made with test sample coils… we have both gen1a and gen2 versions available …

This was his reply 3 days ago

@amal

I do literally only have a couple on the shelf at this point… waiting for a delivery of production qty antennas for these, but the early test units work fine and are in inventory now… just don’t have them listed yet. If you want one, I will DM you with details.

So fingers crossed

Thanks for the tip @Pilgrimsmaster I sent a DM, since I guess Amal is quite buissy and might not get to read every post he’s tagged in

[Pilgrimsmaster]

Absolutely, a very busy guy. He will be busy coming up with new stuff for us…

Thank you for breaking all of that down. Lol I was wondering why a Gen1a magic card I purchased from one vendor didn’t work on my front door, while the one I got from another did. I guess it’s kinda hard to standardize something that’s not supposed to exist.

I found a document from NXP Semiconductors that explains what BCC bits are. It says it’s a calculated value, so I don’t think people are likely to fuck them up. I really have no idea though.

I’m waiting on a Gen1a & Gen2 a to arrive from the company I linked to previously. Is there any way to check if they match the chips you use? I have a Proxmark3 and the tag info app.

Brilliant find… makes sense now. I wonder if writing the wrong BCC bits to a magic mifare chip actually bricks the chip, or rather breaks the ISO14443 standard and thus it is the reader that rejects talking to a the magic mifare chip because the BCC bits are wrong. If that’s the case, then surely a proxmark3 could fix the problem.
