ESP32 BLE beacon compatibility

[Ramyras]

Hello all,
I'm bit new working with ESP32 stuff and some guidance would be helpful particularly about compatibility of different devices.
I want to build on my ESP32 D0WDQ6 setup to read surrounding BLE beacons and based on they presence and possibly distance make some decisions (turn on relay, or send notification and so on...) But problem is that I can't see any beacons (I have couple USB dongles) that are visible for any BLE Scanners on mobile phone but ESP32 do not see them. I can see just some Samsung TV.
I suspects there can be some compatibility issues between ESP32 and surrounding BLEs but can't to understand what exactly.
Any guidance or points to relevant documentation or other resources can help me understand why I do not see BLEs
Thanks in advance

There may be few reasons, but without the code its impossible to say what is causing this.

Hi,

Can your phones detect those BLE devices?

I'm using the eddystone demo that comes with the esp-idf and am having the same problem. I have a Bluegiga module that sees about 8 devices.
