Function llcc68_supports 

Source 
pub const fn llcc68_supports(
    spreading_factor: u8,
    bandwidth: LoraBandwidth,
) -> bool
Expand description

Reports whether an LLCC68 can use a spreading factor at a bandwidth.

The LLCC68 takes the SX1262’s commands but not all of its settings. Its datasheet (DS.LLCC68.W.APP Rev 1.1) lists SF5 to SF11 in Table 13-47 and only the 125, 250, and 500 kHz bandwidths in Table 13-48, and notes under Table 6-1 that not every spreading factor is available at every bandwidth. Semtech’s LLCC68 driver refuses SF10 and SF11 at 125 kHz and SF11 at 250 kHz, which leaves the LoRaWAN data rates the LLCC68 product page lists: up to SF9 at 125 kHz, SF10 at 250 kHz, and SF11 at 500 kHz.

§Arguments

  • spreading_factor - the spreading factor.
  • bandwidth - the signal bandwidth.

§Returns

true when the LLCC68 supports the pair.

§Examples

use pamoja_radios::sx126x::config::{llcc68_supports, LoraBandwidth};

assert!(llcc68_supports(9, LoraBandwidth::Khz125));
assert!(!llcc68_supports(10, LoraBandwidth::Khz125));
assert!(llcc68_supports(10, LoraBandwidth::Khz250));
assert!(!llcc68_supports(11, LoraBandwidth::Khz250));
assert!(llcc68_supports(11, LoraBandwidth::Khz500));
assert!(!llcc68_supports(12, LoraBandwidth::Khz500));
assert!(!llcc68_supports(7, LoraBandwidth::Khz62_5));
