pub extern "C" fn pamoja_lora_messages_per_hour(
    link: PamojaLoraLink,
    payload_len: usize,
    duty_cycle_permille: u32,
) -> u64
Expand description

Returns how many transmissions of a payload fit in an hour under a duty-cycle limit.

A transmission really costs its airtime plus the silence the limit forces after it.

§Arguments

  • link - the link settings.
  • payload_len - the payload length in bytes.
  • duty_cycle_permille - the limit in parts per thousand, so 10 is 1%.

§Returns

The number of whole transmissions an hour, or 0 when the limit is zero.
