Overview AT Commands INSYS WLAN serial 2.1
Command Description
ATS8=<n>
Set waiting period for block formation
Sets the waiting time until a block is sent via the network. The unit is in 1/1000
seconds (1 ms). The time starts to run as soon as a character is received. As
soon as no more data is received from the serial interface during the period set
in S8, a data packet is sent. Small values in S8 lead to faster transmission of
short messages, but increase the number of packets and therefore the load on
the network side. Large packets in S8 lead to a delay of small data packets.
ATS8=2..255
Waiting period in milliseconds
(corresponds to 2ms ... 255 ms)
ATs8=50
50 ms (default)
ATS9=<n>
Set message end character for block formation
Sets the character for ending a message. With this setting, messages can be
sent immediately regardless of the setting in the S8 registry. As soon as the
character defined in S9 is received at the serial interface, the entire data block
collected until then is sent.
ATS9=0..254
Define message end character
ATS9=255
Deactivate message end ID (default)
ATS12=<n>
Pre and post run time for escape sequence
Minimum pre and post run time when sending the escape sequence („+++“)
ATS12=2...255
Time in units of 1/10 seconds
ATS12=10
1 second (default)
ATS<n>?
Query S-registry
n = 0,1,2,3,4,5,8,9,12
Query of the according registry
Access to other S-registries will not lead to errors, but also has no effect. When
reading non-implemented S-registries the value „0“ is returned.
AT*S<n>
Set baud rate
AT*S
sets the baud rate at the serial interface. The following baud rates are
supported:
AT*S1
300 bps
AT*S2
600 bps
AT*S3
1.200 bps
AT*S4
2.400 bps
AT*S5
4.800 bps
AT*S6
9.600 bps
AT*S7
19.200 bps (default)
AT*S8
38.400 bps
AT*S9
57.600 bps
AT*S10
115.200 bps
AT*S11
230.400 bps
AT*S12
460.800 bps
For settings of more than 115,200 bps the actual speed is 1.7 % higher than the
nominal speed (234,375 or 468,750 bps).
