Multi-Advertising...



1) scan can only get ESP_MULTI_ADV_LEGACY (i'm using an old handphone with android lollipop (with nrf connect app),
is that why not able to received the rest of the advertisements? )

2) i have another esp32-wroom-32, with LE capability. can i use that as a scanner on my laptop to scan for
BLE5 multi advertisement ?
(i'm using the below sketch)
https://raw.githubusercontent.com/espre ... d_scan.ino

3) Can i incorporate multi advertisement for multiple eddystone url format?
4) where can i find more info and example for multi advertisement in espressif?

Pls advise.
Thanks
