STEVAL-ASTRA1B advertising packet

The

advertising packet includes the following options:

•

ble_dev_id = 0x0C

, where 0x0C =

•

ble_fw_id = 0x01

for the public firmware (

Astra1 - Asset tracking

)

•

ble_fw_id = 0xFE

for the development firmware

There are three option bytes:
•

battery level percentage

•

Enum String = Use case

(for example,

LOGISTICS

,

GOODS_MONITORING

, etc.)

•

Enum String = System Info

(for example,

Lora Joined

,

GNSS off

, etc.)

Figure 14.

STEVAL-ASTRA1B advertise

The

STAssetTracking

app adds other information, as soon as the board is recognized. The related information

is gathered from a json file downloaded from the web server (for example, firmware version, firmware name,
implemented characteristics, etc.).

4.2

Data exchange

The Bluetooth

®

Low Energy manager configures the device characteristics according to the data exchanged with

the Bluetooth
