I’m trying to work with the as3933 using a demo board that comes with a sender/receiver.
I know how to use/setup the registers to have the receiver detect a given wake up signal and receive data.
However, I’m setting up the receiver (little keyfob) with the pattern correlation off and DAT_MASK disabled to be able to observe the entire demodulated incoming signal (carrier burst+preamble+pattern+data).
This entire demodulated signal should be now accessible on the DAT pin (according to the datasheet).
I’m basically trying to read the data from the DAT pin using an arduino uno: I simply connect the to the DAT pin and do a digitalread() but can’t see to find anything consistent.
My goal is to read the wake-up pattern + data. According to the spec I should see a bunch of 1’s coming from the carrier burst, then some bits for the preambles (1010) and then the pattern+data but nothing there. I even tried to set an interrupt on the WAKE pin (since data starts on rising WAKE) to narrow down where the pattern/data would be but no luck.
Anyone with experience reading and exploiting the data coming from the DAT pin on the as3933 ?
