// TEMPORARY: units shipped with LR1110 transceiver FW 0x0303 (the original 2020 release), which cannot
// reliably demodulate 500 kHz LoRa - Turbo presets fail RX with ~41% byte errors while TX and narrower
// bandwidths are fine. 0x0303 also predates GetLoRaRxHeaderInfos, which computePacketTime() calls on every
// received packet. Confirmed fixed by updating to 0x0307; targeting 0x0402 additionally picks up the
// out-of-band emission fix for consecutive LoRa transmissions (0x0401) and three CVE fixes (0x0402).
// Costs ~240 kB of flash. Remove once the affected units are updated.
