Notes After closing the connection, the device will
attempt to reconnect using the FRIEND list.
The purpose of this command is to provide
an abort to the TCP stack level retries.
Currently, the number of retries is 10 and
the amount of time varies based on
calculated round trip time. The minimum
time allowed is 120 seconds.
Attempts to set the retry timeout to a value
less than 120 or more than 65535 will result
in an error.
