When using a baud rate of 460 kbps or more on
the serial interface, a combination of link policy 1
on the sender and link policy 2 on the receiver
gives the highest throughput. When using a
slower baud rate, then the default link policy
gives equally high throughput.
If the remote device rejects the link policy re-
quested by the SPA, then the red LED gives an
error indication. If the remote device rejects the
link policy, then the default link policy is used.
Command Pa-
rameters
Type Value
link_policy integer Link policy configuration.
0: Default, No sniff, All packet sizes.
1: Sender, No sniff, 5 slot packets
2: Receiver, No sniff, 1 slot packets
3: QoS, No sniff, All packet sizes, Short poll
interval
4: Sniff, interval 10ms, 1 slot packets
5: Sniff, interval 50ms, 1 slot packets
6: Sniff, interval 100ms, 1 slot packets
7: Sniff, interval 200ms, 1 slot packets
8: Sniff, interval 500ms, 1 slot packets
The link policies with sniff may be used to get
a link with a specific response time or to de-
crease the power consumption.
parameter integer Bit 0: Exit sniff on data activity. Only used
when link policy supports sniff.
If set the SPA will try to temporarily exit sniff
when receiving data on the serial interface.
When no data has been received on the serial
interface for 1s, then the link will be put back
into sniff mode. If not set, then the link will
always be in sniff.
Using exit sniff on data activity may be useful
when using longer sniff intervals since these
links have a low throughput.
store_in_startup_database enumerator 0: The setting will only be valid for the current
power cycle.
1: The Serial Port Adapter will remember the
setting between power cycles. The settings
database in the Serial Port Adapter will be
updated.
