can ble beacon receive scan request?

[pail]

hi dev

I'm not sure about beacon, so I'm posting questions to check.

General Ble process is like that

1) peripheral do advertise. during advertising interval, it sends "advertising data" to cental.

2) when central receives "advertising data", it sends a "scan request" to peripheral.

3) when peripheral receives "scan request" from central, it can send "scan response".

4) after that, they are connected each other.

but as far as I know, beacon is a device that keeps advertising without connection.

so does it mean that there is no scan requset and scan response between beacon and ble central device ?

Hi.

Seems that your understanding is correct.

But there is no reason that you can not use scan response with your beacon? Are you having trouble adding it?

hellow joakim,

thank you for your reply

I don't know if you saw it on my previous ticket...

As soon as the central device receives "advertisement data" from the beacon, I want to save the MAC address of the beacon to the central device

And I want to create a structure whenever central device receives data from a beacon, the central device detects a stored MAC address of the beacon, and it does a special action (for example, LED on).

All of this is because I want to connect the center and peripherals (beacons) without pairing and bonding.

And the reason I'm making this is because it's kind of my research topic

You can connect to your device without using pairing/bonding. There is no need to use non-connectable beacons if that is your requirement.
