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.
