Function pamoja_lora_low_data_rate_optimization 

#[unsafe(no_mangle)]
pub extern "C" fn pamoja_lora_low_data_rate_optimization(
    link: PamojaLoraLink,
) -> bool

Reports whether a link uses low data rate optimization.

It is on when a symbol lasts longer than 16 ms, which is SF11 and SF12 at 125 kHz and SF12 at 250 kHz. The airtime assumes it, so a radio set up from these settings must turn it on too.

Arguments

• link - the link settings.

Returns

true when the symbol time exceeds 16 ms.
