Advertising flag, “BR/EDR Not Supported.”, how is it interpreted?

If the “BR/EDR Not Supported.” bit is set as "0" or "1" what does that mean? I have been confused for the last hour about how to interpret it.

If the bit is set as 1, does that mean the "BR/EDR Not Supported" is false which means that BR/EDR is indeed supported? Or is it the other way around with the bit set as "0"?

Solution

  • The following is from BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 3, Part C:

    • For a device of the LE-only device type with all the following flags set as described:

    a) The ‘BR/EDR Not Supported’ flag to set one.

    b) The ‘Simultaneous LE and BR/EDR to Same Device Capable (Controller)’ flag set to zero.

    Having a 1 for the BR/EDR Not Supported flag means it does not support BR/EDR. i.e: it is an LE only device.
