problem with sniffer not detecting probes from some phones

[salar-soltanpoor]

hi I used the code and made a few changes to make it compatible with Arduino platform. I tested it using an esp32 wroom. it is also noteworthy to mention that I modified the sniffing time to 50. the problem is the code only detects the probe requests of my phone which is a Xiaomi Redmi note 11 pro but it doesn't detects the probe requests from older phones of my co-workers. what might be the problem here ?
thanks in advance

Hi,
This is my own version, based on ETS-PoliTO, but with modifications, you could check inside wifi.c
