NB (Parity) Command
<Serial Interfacing> The NB
command is used to select/read the
parity settings of the RF module for
UART communications.
PB (Polling Begin Address)
Command
<Networking & Security> PB
command is used to set/read the
module’s Polling Begin Address –
the first address polled Polling Mode
is enabled.
Polling Operations: The ‘Polling
Base’ (MD = 3) cycles through a
sequential range of addresses,
polling each ‘Polling Remote’ (MD =
4). The base then waits for a
response & proceeds to the next ‘Polling Remote’. Each ‘Polling Remote’ responds by
sending the data from the Data In buffer following the RB & RO parameters. When there is
no eligible data to send, the ‘Polling Remote’ will not respond. The ‘Polling Base’ will move
to the next address in the polling sequence after a short delay.
