update_rescue into your HTTP directory, the URL will be

http://www.myserver.net/streamingclient/update/compound.bin

• create new text file

http://www.myserver.net/streamingclient/update/update.txt containing :

Content of the update.txt

VERSION=1

FW_VERSION =0131

FW_URL=http://www.myserver.net/streamingclient/update/compound.bin

• configure your devices “Update URL” field with

http://www.myserver.net/streamingclient/update/update.txt

• push the “Apply” button on the WEB interface. The device will reboot and

automatically update the firmware. If you want the device to check the update file

every 30 minutes set the configuration field “Remote Update Period” to 30.

IMPORTANT: Remote firmware update is supported only on devices with 2MB

and more flash memory. The flash memory size and availability of the firmware

update can be retrieved from the device WEB UI via the &Lstate parameters 46

and 47.

9.4 How to configure the device remotely

In previous section we configured the HTTP server and the device for remote update

and updated the firmware. In this section we will use the same server and paths

but will alter the file update.txt.

In this example we will change the streaming URLs and set volume to 25% (Volume

range is 0 to 20). Change the update.txt as follows:

Content of the update.txt

VERSION=2

url2=rtp://85.124.188.115:4000

url1=http://vruk.sc.llnwd.net:12265

volume_100=62

The device will change the three configuration fields and then reboot.

In situations where we want to change temporarily (without rebooting) CGI

commands can be used instead of configuration change directives.

The following example shows how to change the volume without rebooting:

Content of the update.txt

VERSION=3

v=10

This way we can issue any CGI command. See chapter WEB for available

commands.

Device dependent update files

Sometimes we need to update devices with different configurations. This can be

easily done using the URL Variable Substitution in the Update URL.

Let us imagine we have two devices and want to load them with different settings

(e.g. to play two different radio stations).

Let us assume the devices have IP addresses 192.168.2.100 and 192.168.2.101.
