SiPy Bluetooth

[sk]

My program isn't finding my phone (which has its bluetooth visible to all). Is there a certain time I need to scan for, currently I scan for 10 seconds.

Program:

from network import Bluetooth
bluetooth = Bluetooth()

bluetooth.start_scan(10)
while bluetooth.isscanning():
    adv = bluetooth.get_adv()
    if adv:
        print(adv)
    else:
        print("NONE")

@jmarcelino is there any way to configure this? Any libraries or plug ins for the board's BT sensor I could use?

@sk
If your phone isn't advertising (as a BLE peripheral) then the SiPy will have no knowledge of it.

@jmarcelino is there any way to see a list of devices that SiPy has found whether or not it is advertising? Bluetooth must do an initial acknowledgement of some sort with other bluetooth devices, right? Is there a way to see the devices they acknowledge?

@jmarcelino Thank you.
I understand the problem now. I just wanted SiPy to act as a sniffer for cellphones with their bluetooth or wifi/hotspot on.

The only way for your phone to appear in the scan is to turn it into a Bluetooth LE (BLE) peripheral device, for example by running some app that puts it into that mode.

Phones are normally BLE central, so they don't advertise on BLE - they only scan for peripherals much like you're doing.

(You may be be thinking of Bluetooth Classic, which is different)
