Over-the-Air Configuration
iWRAP3 has Over-the-Air (OTA) configuration interface, which allows one to configure
iWRAP settings over a
Bluetooth
SPP connection. OTA gives one access to standard iWRAP
commands which also available over UART interface. This example shows how OTA
interface can be accessed from another iWRAP device.

Figure 24:
Over-the-Air connection example
On a remote iWRAP OTA is simply activated by issuing iWRAP command:
SET PROFILE
OTA {
password
}
and by performing a reset.
In the
Bluetooth
interface OTA is seen as a standard Bluetooth Serial Port Profile service
with a fixed service name “
Bluegiga iWRAP
”.
When OTA connection is opened the first thing that needs to be done is to send the
password from the controlling device to the controlled iWRAP. If the password is correct
iWRAP boot prompt will be displayed, otherwise the connection will be closed.
There is a special use case for OTA to remotely read/write the GPIO pins of the iWRAP
under control.
