CONN-GUIDE-BT740_v0.2
This length may still be too big to send to the host in one packet. Therefore the name sends in a similar
fashion to ‘get friendly name’ described above. However, in this case, the event EVT_LCL_FNAME gets
the name to the host.

Note: SENTLEN could be less than MAXBYTES. It can happen if there is no space in the module’s
TX buffer to send events.
8.16.4 Set Local Friendly Name
This command sets the local friendly name in non-volatile memory so that it is used after a power up/reset
cycle.
Since the module can cope with large packets, the name sent to the module in a single command packet
as a null terminated string.
