help
ESP32 does not support switching between 240M and 80M.The root cause
is that when switching between 240M and 80M, we need to disable
BBPLL and then re-enable it with a different frequency.Since the
Bluetooth baseband works from PLL frequency, it will temporarily
lose its 80 MHz clock, while the BBPLL is disabled.
