In the figure above, a WRAP THOR Bluetooth module with iWRAP firmware could be connected to a host system for example via the UART interface. 1. If the host system has a processor, software can be used to control iWRAP by using ASCII based commands or GPIO events. 2. If there is no need to control iWRAP, or the host system does not need have a processor, iWRAP can be configured to be totally transparent and autonomous, in which case it only accepts connections or automatically opens them. 3. GPIO lines that WRAP THOR modules offer can also be used together with iWRAP to achieve additional functionality, such as Carrier Detect or DTR signaling. 4. Audio interfaces can be used to transmit audio over a Bluetooth link. 13

In the figure above, a WRAP THOR
Bluetooth
module with iWRAP firmware could be
connected to a host system for example via the UART interface.
1.
If the host system has a processor, software can be used to control iWRAP by using
ASCII based commands or GPIO events.
2.
If there is no need to control iWRAP, or the host system does not need have a
processor, iWRAP can be configured to be totally transparent and autonomous, in
which case it only accepts connections or automatically opens them.
3.
GPIO lines that WRAP THOR modules offer can also be used together with iWRAP to
achieve additional functionality, such as Carrier Detect or DTR signaling.
4.
Audio interfaces can be used to transmit audio over a
Bluetooth
link.
