Techniques are described herein for low power page scanning through identifier sensing. An example method includes a first computing device determining that an operation of a first core of the first computing device during a first duration corresponds to a paging message scan by a second core of the first computing device scheduled during a second duration. The first computing device can determine the operation of the first core prevents transmission of a paging message response for establishing a connection with a second computing device via a short range transmission protocol. The first computing device can determine a third duration for the paging message scan such that the operation of a first core does not prevent the transmission of the paging message response. The first computing device can cause the second core to scan for a paging message during the third duration.
