Send and receive bits

[mariliahoshino]

I'd like send and receiver bits of data,not character
I will use in maintenance of machine

I'd like set the bits 32 33 and 34
I need sent slot of zero and position 32 33 and 34 send 1
I need sent this 000000000000000000000000000000 0111000000000000000000000000000000

Tks

I suggest creating a custom struct in C (e.g. bit field [1]) and sending it as bytes.
Sending individual bits via API calls is typically very inefficient.
