Figure 5: 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.

2.6 Multipoint
It is possible to configure a module to support up to 8 parallel Bluetooth connections. These connections can be
to 1 central and 7 peripherals in a multirole configuration. The AT+UBTCFG command is used to set the
maximum number of Bluetooth connections.
In data mode, data is transmitted over air to all the connected devices and the data received from remote
devices is interleaved.
Figure 7: Wireless Multidrop
In extended data mode, it is possible to transmit data to a specific remote device and to know from which
remote device data is received (see u-blox Extended Data Mode Protocol Specification [7]).
