Lopy4 to Lopy4 with BLE get_adv() always none [Solved]

[Amarulp]

Hello everyone!
I was trying to connect two Lopy4 with BLE, but bluetooth.get_adv() is always returning none. Just in a few cases it and using the same code work but then stopped.

import ubinascii
from network import Bluetooth
from time import sleep

bt = Bluetooth()
bt.init()

bt.set_advertisement(name="lopy", manufacturer_data="lopy_v1")
if bt.isscanning():
    bt.stop_scan()

bt.start_scan(-1)
while bt.isscanning():
    adv = bt.get_adv()
    if adv:
        print(adv)

Both with the same code, and different names (I also try it with the same name)

Thank you

Thank you so much!
It worked! Also, it can scan and advertise at the same time.

@amarulp Hello, I think you cannot, at same time, advertise and scan for device with a lopy but you can test it in case, with some luck it can work.
I suggest you to have on one lopy to advertise (btw you must add in your code bt.advertise(true) after your bt.set_advertisement according to documentation) and the other lopy do bluetooth scanning.
