2 Key features

The possibility of replacing serial cables with simple wireless connections is a key feature of u-blox modules. It allows system hosts to transfer data to one another over wireless Bluetooth connections that are established between u-blox modules in Central/Peripheral configuration. Depending on the module capabilities, data from each host is transferred to local u-blox modules over a serial UART interface. u-blox modules can be configured to automatically establish new connections and/or accept incoming connections using AT commands. For connected hosts, this means that physical serial cables can be replaced with more convenient wireless solutions.
