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:

.. code-block:: none

   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:

  +-------------+-------------------------------+---------+
  | Value       | Signal Strength (dBm)         | Level   |
  +=============+===============================+=========+
  | A7H to 80H  | -89 or less                   | 0       |
  +-------------+-------------------------------+---------+
  | A8H to ADH  | -88 to -83                    | 1       |
  +-------------+-------------------------------+---------+
  | AEH to B4H  | -82 to -76                    | 2       |
  +-------------+-------------------------------+---------+
  | B5H to BEH  | -75 to -66                    | 3       |
  +-------------+-------------------------------+---------+
  | BFH to FFH  | -65 or greater                | 4       |
  +-------------+-------------------------------+---------+
  | 63H         | Not known or not detectable   | /       |
