"AdvData" field structure (max 31 octets/bytes):
| Length | length of the payload | 1 octet (15) |
| Type | manufacturer specific data | 1 octet (ff) |
| ManufacturerData | company identifier |
| 2 octets ( |
15FF4F094F09) | ||
| Version | the version of this advertisement structure | 1 octet (uint) |
| UserData | user-configured part of the payload | 1 octet (uint) |
| Secret | optionally encrypted (AES-ECB) part of the payload |
|
| Info |
|---|
Please note that all multi-byte values are in little-endian. Meaning, that if, for example, you want to get the temperature value and #14 and #15 octets indicate the temperature as "a1 19" ("plus" temperature) → the real temperature value is going to be (0x19a1)/256 = 25.6 C. |

Example
An example of the payload configured in MikroTik's format (non-encrypted) would be:
...
15ff4f09 (first 4 octets) → ManufacturerData. Is the same (constant data) for every MikroTik format's payloadLength (0x15 hex-to-dec is 21). Type (0xff). Company identifier (0x4f09).
01 (4th octet) → Current version of the payload's structure. Should be the same for every payload (constant data).
...
5f (21st octet) → battery percentage of the tag = 95 %. 0x5f from hex to dec is95.
| Info |
|---|
Starting with v7.11, you can use the Peripheral Device section or/and Decode-ad feature to view decoded values! |
Script for decoding
Add a new script under the "System>Scripts" tab and import the script there (for non-encrypted payloads).
