Patent attributes
The present disclosure describes methods and apparatuses for location service offload for Bluetooth positioning. In some aspects a Bluetooth radio frequency (RF) signal is sampled by a Bluetooth transceiver to produce a set of samples corresponding to an advertisement packet and the set of samples are stored in a shared memory. Another transceiver is signaled that the set of samples are stored in the shared memory, causing the other transceiver to generate the Angle of Arrival (AoA) of the Bluetooth RF signal. A signal is received from the other transceiver indicating that the generated AoA is available in the shared memory. The generated AoA is read from the shared memory by the Bluetooth transceiver and sent to a host processor. By so doing, data transfer between the Bluetooth transceiver and the host processor is reduced, as well as, reducing the computational load on the host processor.
