Mancester decoding issue

Okay, you might want to check out:

… which talks about a CC1101 decoder that is also available in the “Extensions” tab of the Logic 2 GUI. With that High-Level Analyzer, you can dig into the SPI messages to the CC1101 chip.

My guess is that the high-level information you are looking for, such as:

… is buried deeper in the lower-level SPI data stream.

Thus, you’ll need to dig into the CC1101 chip and specifically the datasheet to learn more about what information actually is being passed in between MCU and the IC.

[Edit] I am curious how ISO 15693 which is at 13.56 MHz is being interfaced with a CC1101, which runs at higher frequencies (315/433/868/915 MHz)? This could also be part of your problem – they may have some clever use of the hardware, but then do some software-level decoding of the bitstream, such that the hexadecimal values you’re looking for are not present in the low-level SPI traffic.
