Programming interface
3.3 RPC calls
Since the commands to be transmitted in the wireless network do not reach the transponder
or reach it incompletely, no event message is generated in this case.
If an RPC call sets a field form to a value that is already set, an event message is sent
immediately. This happens during or very shortly after the RPC call. Event messages are sent
when a situation is reached.
If a field content still to be transmitted is overwritten again before the previous value could
be sent to the transponder, only the value set last is transmitted to the transponder. In this
case, only the writing of the last value is acknowledged by an event message.
The transmission of background images, fonts and theme files is given higher priority and
temporarily interrupts the transmission of text content.
