SPP
RFCOMM frame size for all RFCOMM based profiles.
23-512 range has a granularity of 1; 512 to 4096 range
has a granularity of 4.
For example: Setting 4095 sets a value of 4092 (round
down new values).
Note: Testing and calculations by our stack vendor show
that the incremental benefit above 990 is not worth
the downside of handling larger payloads.

General / GAP
Link supervision Timeout in seconds.
This value only reads on power up when the profiles are
registers. After changing the value it needs committed to
non-volatile memory using AT&W or
CMD_SREG_STORE and then the module needs a power
cycle.
