Could someone help me understand what these lines mean and the data in them? How do I make it intelligible?

Encontrado:, 33: C0: AB: 09: B7: 2C, RSSI = -55, (MyMap) {-1 = [B @ eefdf2c, 0 = [B @ a299df5}
Encontrado:, 17: D3: 81: 66: 0E: 04, RSSI = -79, (MyMap) {-1 = [B @ 257178a, 0 = [B @ 6fd41fb}
Encontrado:, 5F: 6D: B8: F8: 78: A7, RSSI = -76, (MyMap) {-1 = [B @ aebf573, 0 = [B @ 532bc30}
Encontrado:, 17: D3: 81: 66: 0E: 04, RSSI = -79, (MyMap) {-1 = [B @ 910f0a9, 0 = [B @ 140262e}
Encontrado:, 33: C0: AB: 09: B7: 2C, RSSI = -57, (MyMap) {-1 = [B @ 98675cf, 0 = [B @ 33f6b5c}

Encontrado:, 40: C9: F3: BF: 3B: 34, RSSI = -71, (MyMap) {1 = [B @ 2d50be1, -1 = [B @ f5acd06, 0 = [B @ cc54fc7}

My best *guess* is the first two fields on each line are MAC addresses and signal strengths. So you have a list of nearby WiFi devices.
The rest of the items are probably meaningless to anyone unless you explain what you are trying to do - ideally with an example project attached.

[B = array of bytes

B4X:

Dim bc As ByteConverter
For Each k As Object In YourMap.Keys
 Dim b() As Byte = YourMap.Get(k)
 Log(bc.HexFromBytes(b))
Next

Hi MikeSW17, I want to identify the ESP32 I am using. I need to tie my android app with that ESP32 that is running a machine that I also created.
