No-one will read a bunch of 10101.

Before you repost, make sure you have a clear idea of the problem you’re
experiencing, and find a way to convey it to us in a clear fashion.

In your post, you also forget all relevant information, most
importantly which modulation you used, and how your receiver is
structured (or was it one of the stock receivers?).

If it helps, the packet framer actually inputs bytes, not bits. So thats
8 bits of information per byte. So rather than 1/0, you have 0-255 as
possibilities. – not sure if that effects your experiment, just FYI
