Publication number: 20230117443Abstract: An exemplary hearing device is configured to receive, from a source, a data packet, the data packet including a plurality of frames including a first frame and a second frame. The hearing device determines that the data packet has an invalid checksum. The hearing device accesses, in response to the determining that the data packet has the invalid checksum, a first frame checksum for the first frame and a second frame checksum for the second frame. The hearing device determines that the first frame checksum is invalid and that the second frame checksum is valid. The hearing device discards, based on the first frame checksum being invalid, the first frame and stores, based on the second frame checksum being valid, the second frame.Type: ApplicationFiled: February 24, 2020Publication date: April 20, 2023Inventors: Alessandro Gallo, Federico Ferrari
