Data 100 (Wi-Fi Hotspot)

The Wi-Fi hotspot information collected by terminal scanning.

Each Wi-Fi hotspot occupies 7 bytes, including MAC and RSSI.

The frame format of the Data 100 unit is as follows:

For example (Total 17 bytes):
64 0F 02 C8 D3 A3 4C 64 00 B0 C2 D3 A3 88 45 99 B3

  • Number

    Indicates how many Wi-Fi hotspots the following data comes from.

    If the value of this field is 00H, no other fields are included.

  • MAC

    The MAC of a Wi-Fi hotspot.

    For example, C8D3A34C6400H means MAC “C8-D3-A3-4C-64-00”.

  • RSSI

    The received signal strength.

    Expressed as an 8-bit signed integer and the unit is dBm. When the RSSI value is less than -128 (80H), it is also filled in as 80H, and when the RSSI value is greater than -1 (FFH), it is also filled in as FFH. In particular, 63H means the signal strength is not known or not detectable.

    Typical values are as follows:
