5.2.2 Periodic Sampling
The ZE20S can be configured to send its I/O status to a remote device at a periodic rate. To configure this
way, please use the AT commands below:
AT+DESTLA=<IEEE address><CR>
Where <IEEE address> is the long address of a remote node to send sampled GPIO values of local node.
ATS42=<value><CR>
Where <value> is the GPIO sampling period in seconds. If set to 0, GPIO monitoring is disabled.
ATS43=<value><CR>
Where <value> is the GPIO monitoring node. If set to 0, the monitoring node is selected by AT+DESTLA.
If set to is 1, the sink node is set as the monitoring node.
ATZ<CR>
Reset the device to apply the changes
Also the ZE20S can be configured to display periodic sampling data coming from the other nodes. To
enable this feature, please use the AT command below:
ATS11=<value><CR>, where <value> determines whether incoming message will be presented or not. If
a user wants to display incoming message in command mode, S11 should be enabled.
If this feature is enabled, incoming message will display in the form of:
++<IEEE address>|<GPIO value><CR>.
5.2.3 Change Detection Sampling
The ZE20S module can take an I/O sample and transmit it to a remote device immediately whenever a
monitored digital I/O pin changes state. It is possible to configure it with periodic sampling simultaneously.
To configure this way, please use the AT commands below:
AT+DESTLA=<IEEE address><CR>
Where <IEEE address> is the long address of a remote node to send sampled GPIO values of local node.
