Question

Someone who can help me with the correct parsing settings (Type, Data Offset, Data Size etc.) of my raw BLE Eddystone TLM sensor:

I need the Reserved value as BLE Custom 1  IO data element:

Answer 1

Hello Stefan,

Good day. Thank you for the query. From the raw data that you have provided, please try out the following settings:

First line :-

Type: FE - indicate to work with the whole data packet and not just a single data type or simply means to look from the start of the packet

Data Offset: 14 – indicates that the device will look from the 14^th byte for the Match i.e AAFE

Data Size: 2 – size in bytes of AAFE

Action: Match – Validate a certain data in packet, i.e AAFE

IO: None - Only selected if the action is SAVED, otherwise its None.

Match: AAFE - hex string to be matched with BLE sensor data

Endianness: little endian - endianness of data:  (ex. 0x1122). Used only with Save action.

Multiplier: 1 - value to be used to multiply output data. Used only with Save action.

Offset: 0 – value to be added to output data. Used only with Save action.

Second line :-

Type: FE - indicate to work with the whole data packet and not just a single data type or simply means to look from the start of the packet

Data Offset: 34 – indicates that the device will look from the 34^th byte for the reserved data i.e. C73E29B3

Data Size: 4 – size in bytes of C73E29B3

Action: SAVE – Save data to AVL record

IO: Custom – type of BLE sensor used shows to which I/O element data will be saved, in this case it's Custom, so it will be I/O Parameter BLE Custom 1 and the corresponding parameter has to be enabled in the configuration for it to be sent to the server

Match:  leave blank – since IO has been selected

Endianness: little endian - endianness of data:  (ex. 0x1122). Used only with Save action.

Multiplier: 1 - value to be used to multiply output data. Used only with Save action.

Offset: 0 – value to be added to output data. Used only with Save action.

For reference on how the selection was made, you may refer to https://teltonika-gps.com/downloads/en/blue-coin-t/Sensor-and-Beacon-testing-instructions-v1.2.pdf from page 8 onwards.
