Bluetooth file transfers using FTP do not provide upper-layer reliability checking and rely on the Bluetooth device physical layer providing reliable data to upper layers of a Bluetooth stack. However, reliability checks implemented by the physical layer are typically not very robust and in some cases may fail to detect errors, thus may provide corrupted data to the upper layers for further processing and may result in data corruption/transfer failure. Non-FTP Bluetooth file transfers are typically more robust when it comes to reliability checking because of upper layer reliability checks. Functionality can be implemented to vary packet transmission parameters depending on a Bluetooth profile implemented on a communication link. A packet error rate of received packets can be compared against a different set of thresholds depending on whether the Bluetooth profile is an FTP profile. Appropriate values of packet transmission parameters can be selected based on the above comparison.

Profile-based packet rate adaptation for wireless systems

System and method for operating a wireless narrowband receiver. A signal may be received on a channel of the wireless narrowband receiver. At least a portion of the signal may be received from a first wireless narrowband transmitter. The wireless narrowband receiver may implement an adaptive frequency hopping algorithm. It may be determined if interference is present on the channel and one or more errors are detected in receiving the signal. In response to determining that interference is present on the channel and one or more errors are detected in receiving the signal, received signal strength of one or more neighboring frequencies of the channel may be measured, and the resulting measurements may be stored in a memory. The measurements may be used to determine interference sources interference on the channel.
