1. A first device, comprising:
a first communication interface using a first wireless communication protocol;
a second communication interface using a second wireless communication protocol, wherein signals communicated over the second communication interface have a shorter range compared to the first communication interface; and
a controller configured to manage communications between the first device and a second device, wherein the first device and the second device form a wireless body area network of medical devices, and wherein the controller comprises one or more processors configured to:
determine a security level for data to be transmitted from the first device to the second device; and
transmit the data using the second communication interface based on determining that the security level for the data is higher than that associated with the first communication interface, wherein to transmit the data using the second communication interface, the controller is configured to:
establish a communication channel to the second device using the second communication interface, or
switch to the second communication interface after establishing an initial communication channel using the first communication interface.
