(7/30/26 Draft version) 1.2.9.nnn - Enable Mobile Document Features

Property OID

1.2.9.1.1.1 / 0x010209010101

Name

Mobile Document Subscription

Description

Set the subscription period using a secured OID that stores ValidFrom (bytes 0–7) and ValidTo (bytes 8–15) as 64-bit Unix epoch timestamps. The OID shall be written using D112 (Set Property – Secured) encapsulated in EEEE (Send Secured Command to Device).

The payload uses 64-bit Unix epoch timestamps for forward compatibility. On current devices, each timestamp shall fit within a 32-bit Unix epoch value; therefore, the most-significant four bytes of each 64-bit field shall be 00 00 00 00.

The payload consists of two 64-bit Unix epoch timestamps:

Bytes 0–7 — ValidFrom

· Unsigned 64-bit Unix epoch timestamp, little-endian

Bytes 8–15 — ValidTo

· Unsigned 64-bit Unix epoch timestamp, little-endian

Disable subscription: All 16 bytes = 0x00.

Enable example (2026-07-14 through 2027-07-14):

· ValidFrom: 0x000000006A557C00 (2026-07-14 00:00:00 UTC) LE

· ValidTo: 0x000000006C36AF80 (2027-07-14 00:00:00 UTC) LE

· Full payload: 00 7C 55 6A 00 00 00 00 80 AF 36 6C 00 00 00 00

Validation rules (SET rejected if violated):

· Length must be exactly 16 bytes.

· Both timestamps equal to 0x0 are accepted (disables subscription).

· One timestamp equal to 0x0 and the other non-zero is rejected.

· ValidFrom shall be less than or equal to ValidTo.

· Each timestamp shall have the most-significant four bytes set to 00 00 00 00 and shall not represent a date later than 2099-12-31 23:59:59 UTC.

Securing Key

Refer to Command 0xD112 – Set Property (Secured). SET shall be delivered using Command 0xEEEE - Send Secured Command to Device.

Mobile Document Expiration Notification

Description

Specifies when the device begins sending Subscription Expiring Soon notifications before the configured subscription expiration date, and how frequently those notifications are sent.

Byte 0

0x00 = Notifications disabled

0x01–0x5A (1–90) = Start notifying this many days before ValidTo;

Send once per calendar day while

ValidTo − N (Byte0) ≤ today ≤ ValidTo

Example:

ValidTo = 2027-07-01

Byte0 = 0x03

Notifications are sent on these dates:

2027-06-28

2027-06-29

2027-06-30

2027-07-01

Byte 1

0x01–0x18 (1–24) = Send one notification every N hours
