There isn't any IMEI linkage. I think the post you reply to is implying the link between Bluetooth MAC address to IMEI could be established by a state actor. That isn't the case though, due to Bluetooth MAC address randomisation, which the paper does address - the 10-minutely identifiers advertised are updated in sync with the local device updating its own MAC address, to prevent correlation between the last MAC address and next one.
