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

. 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:

, and ending with device paired with

Index

value:

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

https://www.qeedji.tech

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

on the Web site

https://www.qeedji.tech

☛

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

on the Web site

https://www.qeedji.tech

☛

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.
