SPP Service “CONFIG”
This service enables access to the AT command interface and, thus, to device
configuration. For a detailed description of this, refer to the Section “AT
Command Interface”.
4.2
AT Command Interface
Access to the AT command interface of the WSA is gained via either the service
or radio interface, but not both simultaneously.
Figure 3: Access to the AT command interface via the radio interface (SPP “CONFIG” service)
Figure 4: Access to the AT command interface via the service interface
As two simultaneous links are possible using the radio interface, the WSA's AT
command interface can be accessed via one link. At the same time, the second
link can be used to access data on fieldbus couplers/controllers or transducers.
