[SOLVED] Sending 25 bits at 1200bps
hey,
i got assignment investigate signal dog collar sending. used sdr signal , decoded 7 buttons , got this:
if notice, there 25 bits being sent in time period of 0.02 seconds. (i'll assume bps generic 1200).
now job make arduino transmit signal, receiver gets same thing. i'm kind of lost here... have 315mhz module needed, , have experience using virtualwire it, not sending raw binary over.
does know how send 25 bits using 1200bps? 25 bits abnormal thing... that's is. far googling solutions have found solutions sending bytes (8 bits) , nothing 3 bytes , 1 bit
attached .wav baseband recording of button (1) being pressed. if it's not possible send 25 bits, there way can play .wav file data port of transmitter?
thanks in advance!

did open collar or receiver see chips inside ?
the decoded '1' , '0' differ 4 bits. half byte.
you use virtualwire or radiohead transmit byte, or sent 25 bits. can transmit 4 bytes (4 bytes = 32 bits).
the major problem how create signal recogned receiver. helpful if protocol known.
when dog collar cheap, 2262/2272 chips.
