Hi, Anyone know how to parse a bitstring? I have values like this : <<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>> coming in from a sensor. I need to get 65 ad 100 out to of that without changing them to another number. Anyone have an idea as to how to do that? Thanks

Here you go: iex> :binary.bin_to_list x [170, 192, 65, 0, 100, 0, 61, 86, 56, 171]

Something like this: iex> x = <<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>> iex> << _ :: bytes-4, onehundred :: bytes-1, _ :: bytes-1, sixtyone :: bytes-1, _rest :: binary >> = x <<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>> iex> onehundred "d" iex> sixtyone "=" This assumes you want the f…

I’m sorry If I wasn’t clear. When I said I wanted to get 65 I mean literally a “65” from that bitstring. As in I want a list of all of the number values. Ex: a = <<170, 192, 65, 0, 100, 0, 61, 86, 56, 171>> b = some_function(a) b == [170, 192, 65, 0, 100, 0, 61, 86, 56, 171]

Yes, it is. Everything in Erlang is available in Elixir.

Is this from the Erlang library?
