3.17 Data request
This command sends back the code of the eventual transponder that is present
in the buffer. When ‘continuous’ mode is enabled, the reply is immediate
because the BLUEBOX sends back the data hold in the buffer that is managed
by the ‘continuous’ identification activity; otherwise, the BLUEBOX performs
readily the identification task under time out protection and sends back the
result of the operation.
