During a new design I am planning to use an RF 433MHz Key Fob transmitter. The supplier tells me that they are coming in three types, depending on the transmitted data format.
Unfortunately, the supplier cannot give me any information of what is the meaning of each format nor any explanation, because he is not technical.
Does anybody have the experiense on this issue to help me?
What is the meaning/difference of these 3 types? Are they software protocols, hopping data protocols etc. ?
Has anybody developed something similar to help me on the decoding code?
Thanks in advance.
