   I am trying to decode OOK (ASK) from LP801B based 433Mhz remote (or similar PT2262)

   it has 24bit packet 16bit address and data

   sync short/wlong + 24bits

   short/long = 1
   long/short = 0

   example:
   (received before state machine (w) )
   " 1 19 1 2 2 1 1 2 2 1 1 2 1 2 1 2 2 1 1 2 1 2 1 2 2 1 1 2 2 1 1 2 2 1 2 1 2 1 1 2 1 2 1 2 1 2 1 2 1 2"

   it is:
   sync + 01 10 01 10 01 01 01 10 01 01 01 10 01 10 01 10 10 10 01 01 01 01 01 01

   01 10 01 10 01 01 01 10 01 01 01 10 01 10 01 10 10 10 01 01 01 01 01 01

   1010111011101010 00 11 11 11

   so problem:
   i can see data going into state machine, but no output, pls someone help me find my mistake! here is the soruce http://kaspars.id.lv/rf12b/ook433.pde

   I solved it! http://kaspars.id.lv/rf12b/433ookrx1.JPG

   It was something with data lenght (word...long...) now it decodes nice, maby will need to fine-tune the pulse sensing lenghts. code here http://kaspars.id.lv/rf12b/ook433.pde (updated file)

   Hello,

   Are you using a JeeNode/JeeLink to do the receiving? or are you using a dedicated 433MHz receiver? if so, what type of 433 MHz receiver are you using?
   Could you please provide a reference number from an online shop as an example?
   I am interested in receiving OOK, but thought it was not possible with the RF12 radios...
   Thanks

   Hi,

   In europe you can get the receiver from aurel, an italian company. They are cheap and work great. (I did the decoding of an other 433.92 Mhz wireless remote with it.)

   The AC-RX usually is just right.

   Yes, i am using 433Mhz AM receiver, just like JC. Any receiver similar (http://www.seeedstudio.com/depot/433mhz-rf-link-kit-p-127.html or else) will work. i used this one http://www.argus.lv/pub/datasheets/BC-NBKsf.pdf (cheapest available locally).
