Bluetooth Low Energy link can not be maintained when using LFOSC only
Revisions Affected

Description
A small percentage of devices do not maintain a Bluetooth
Low Energy link if LFOSC is used as a sleep clock due to random timing error above
500 PPM.
Workaround
A software workaround are available in the SimpleLink F3 SDK
>= 8.10.xx to allow devices to operate in the broadcaster, observer and
peripheral roles when using LFOSC only. When the software workaround is used, the
device can see short periods of operation with reduced throughput and increased
power consumption when the timing error occurs. This software workaround does not
support the central role. To completely avoid the consequences of increased power
consumption and connection throughput or support the Central role, TI recommends
using an external 32.768kHz crystal.
