# ========== LoRa Power Saving ==========
|
||||
# RX duty cycle defaults are in Kconfig:
|
||||
# ON for companion + SX1262/LLCC68 (safe, saves 60-70% RX current)
|
||||
# OFF for repeaters (latency > battery) and LR1110 (mid-preamble bug)
|
||||
# Override at runtime via CLI "set rxduty on/off".
|
||||
|
||||
# ========== ZephCore Log Levels ==========
|
||||
# Defaults are INF for all modules (Kconfig default — no explicit =y needed).
|
||||
# Override per-module on command line if needed:
|
||||
# -DCONFIG_ZEPHCORE_BLE_LOG_LEVEL_DBG=y (BLE adapter only)
|
||||
# -DCONFIG_ZEPHCORE_MAIN_LOG_LEVEL_DBG=y (mesh, companion, basechat, utils)
