# RAK6421 WisMesh Pi HAT — RAK13302 (SX1262 + 1W SKY66122 FEM) in SLOT 2.

repeater_sx1262_cs_id: 1 # CE1 (BCM 7)
# -1 = hardware CS via spidev. The kernel spi driver owns the CE line, so a
# manual cs_pin here fails with EBUSY; manual CS is only for boards whose NSS
# is wired to a non-CE GPIO (e.g. Waveshare).
