User's Manual

It is important for the host to ensure a clean Bluetooth disconnection of any active links before the

bypass mode is invoked. Therefore, it is not possible to have active Bluetooth links while operating the

bypass mode.

The current consumption for a device in UART Bypass Mode is equal to the values quoted for a device

in standby mode.
