Hi, i own some fishing alarms like


And my dog, have eat receiver, so now they are just pinging, but i can't go far away without remote receiver.

I want to rebuild it, i have logic analyzer, i received some packets with 433mhz receiver, i see that packets actually are not that long, and they are repeating, and i can assume that

risin+falling (200 + 200 us) is 1 or 0
falling+rising (200 + 200 us) is 0 or 1

But im not sure, there is also some data with 240us length low or high, or with 160, or with 440
Here is screen of data from one alarm


here form another

Im not asking to do job instead of me, maybe some one have done same, or you seen similar protos, i will appreciate any help

Thank you.
