All RPC calls (Remote Procedure Call) received by the programming interface are answered
immediately. This means that there is no need to wait for an acknowledgment of the RPC call
until the data transfer is completed. The completion of the data transmission is con󹪝rmed by an
event message provided for this purpose. The various event messages can be found in the
section "AUTOHOTSPOT".
The positive acknowledgment of an RPC call does not guarantee or indicate successful
transmission and display of new display contents on the transponder. This can happen if, for
example, the transponder was switched o󹪜 during this time or is not within radio range. Since
