# Some older bootloaders ignore the request and we fall back to 20 B writes.

# settle after a reset before it'll accept another START_DFU.

# Seconds to wait after a *post-connect* failure (response timeout, protocol
# error, link drop mid-stream). SDK 11-era bootloaders (stock Adafruit /
# RAK4631) that wedge mid-DFU only unstick when their internal inactivity
# watchdog fires — usually 60-120 s. Pre-connect failures still use the short
# retry_cooldown above.

# Default 0. Crank to 8 for max range; anything not in the list is
# silently rejected and the SoftDevice keeps the previous level.
