The “force_turbo=1” was part of the solution, if you wanted to *keep* BT
functionality
Eric’s already fixed this. The section:
------------------------------------------------------------------------
# Disable Bluetooth so serial-tty speed is no longer tied to CPU speed
dtoverlay=pi3-miniuart-bt-overlay
force_turbo=1
------------------------------------------------------------------------
Just adding the dtoverlay above resolves the issue. Eric can remove the
“force_turbo=1” on his Pi 3 & confirm the serial port is still reliable.
