Hi Marcel!
When I ran my main program with "hcidump -t"
running in other terminal, the following occurs:
When I choose an item and then the other menu, for
which the items are found in MySQL DB, is generated,
the hcidump -t shows

Then when I choose other item and wait for generating
other menu, where the items are also found from MySQL
DB, the hcidump -t shows

Then does it mean that the items are too much that
the sending of AT command from PC to T610 has delay?
And what is the cause of the delay?
