Figure 4: Data mode
The extended data mode is a simple protocol for the UART, which enables transmission of data to one
specific remote device and also informs the remote device from where the data originated. It is also
possible to execute AT commands as part of the extended data mode protocol. Hence, it is not
necessary to enter the command mode from the extended data mode.

☞
No extended data mode protocol data is available over the air. Only "raw" data is transmitted in the
same way as in the data mode over air. Hence, it is possible for one side to be configured for
extended data mode and the other side for the standard data mode.
