Working with a hub
The SLATE106 device can work with a
SMH300
hub. In this case, the picture .PPK is generated by the hub then it is downloaded by the SLATE106 device through
WPAN1
.
The
SMH300
hub is able to work with up to 20 SLATE106 devices. A configuration must be done first to pair each SLATE106 device to the
SMH300
hub. Each SLATE106
device has an index value, between the
Index
valie
1
to
20
. Thanks to this
Index
, the .ppk picture to be displayed is stored in the
SMH300
hub appropriate WebDAV
director (one directory for each SLATE106 device).
WPAN1
The communication between the hub and the SLATE106 devices is done over
WPAN1
, BLE 4.1 protocol (Bluetooth Low Energy). Each SLATE106 device makes periodically
some connections with the
SMH300
hub. In case the .ppk picture to display is different from the current one, it downloads immediately the new .ppk picture then
displays it.
The BLE communication is exclusive and implies that the
SMH300
hub can communicate with only one SLATE106 device at a time.
Every 15 minutes (default and minimal period value), the
SMH300
hub starts to communicate with all the paired SLATE106 devices the one after the other, starting with
device paired with the
Index
value:
1
, and ending with device paired with
Index
value:
20
.
Pairing
To pair the SLATE106 device to a
SMH300
hub, connect to the Web configuration interface of the SMH300 hub and
Activate
the pairing process. For further information
about the pairing process with the
SMH300
hub or configration modification, refer to the
SMH300 User manual
on the Web site
By default, the SLATE106 device is configured to wake-up every 15 minutes. And the
Test card
is displayed.
So, wait for max. 15 minutes until the device is waking-up and is automatically detected by the
SMH300
hub and the pairing process is finalized.
☛
It is possible to not wait 15 minutes by forcing a SLATE106 device wake-up by plugging for 3 seconds a USB power bank (or to a labtop having an USB 2.0
connector)
☛
In case issue to complete the pairing configuration, ensure with the
APPLI.HTA
(application for SLATE106) that the keycode
Receive Message Overlay over WPAN1
is unchecked
.
Test card removing
To be able to display a .ppk picture other than the
Test card
content, the
Test card
needs to be inactivated in the
SMH300
hub Web configuration interface. For
further information, refer to the
SMH300 User manual
.
☛
The SLATE106 device has to wake up to be able to take a new configuration (add, modifiy or remove the
PIN code
, add or remove the
Test card
, change the
hostname)
When the
TestCard
is disappearing, do consider that the SLATE106 device is paired to the hub and is ready to update its .ppk picture.
SMH300 WebDAV directory .ppk picture update
Each time the .ppk picture of the appropriate SMH300 hub WebDAV directory
http://<SMH300_IP_Addr>/.output/n/
is updated, the SLATE106 device should display the
new .ppk picture is less than 15 minutes after (in default heartbeat value configuration).
☛
Some applications running with the
SMH300
hub allows to update the .ppk picture of the appropriate SMH300 WebDAV directory
http://<SMH300_IP_Addr>/.output/n/
. For further information, refer to the
SMH300 User manual
.
☛
To save battery energy, the .ppk picture is only updated when the new
HUB.PPK
picture is different. If the SMH300 hub WebDAV directory
http://<SMH300_IP_Addr>/.output/n/
is empty or the .ppk picture (default name :
HUB.PPK
) has not been updated, the SLATE106 device can not update its .ppk
picture. In case issue, check first that the
Index
associated to your SLATE106 device is correct.
.ppk update time
When the communication between the SLATE106 device and the SMH300 hub is very difficult, the .ppk picture downloading time for a new .ppk picture is lower than 10
seconds. This duration is used to compute the .ppk picture downloading success rate.
System files
When the pairing is successful, and the .ppk picture updated, these files are available on the USB mass storage:
.PAIRED
: present if the device is paired (or has been already paired) to a
SMH300
hub
HUB.PPK
: .ppk picture to display (propriety format) when
TestCard
is not inactivated. Default file name:
HUB.PPK
. This file name can be modified.
APPLI.CFG
: When the SLATE106 device is paired to a SMH300 hub, it inherits of the configuration file provided by the
SMH300
hub. So, in this case, do not modify
this file from the USB mass storage.
APPLI.HTA
: application allowing to edit and save parameters in
APPLI.CFG
file. When the SLATE106 device is paired to a SMH300 hub, it inherits of the
configuration file provided by the
SMH300
hub. So, in this case, do not execute this application from the USB mass storage.
