Whether the RFU bit in the advertising package can be used to represent custom meanings

[Xphiting]

Hi,

I want to use the RFU bit in the advertising package to indicate the custom meaning, what I should do.

RFU means reserved for future use by the BLE spec, so it can't be used for other/custom purpose no.

Thank you for your answer. I've got it.
