Method and system for Bluetooth low power link layer connection setup |
摘要 |
A mobile device such as a Bluetooth low energy (BLE) device detects out-of-band blocking signals and manages packet transmission in associated BLE link layer connections based on the detected out-of-band blocking signals. The BLE device is operable to measure out-of-band RSSI to detect out-of-band transmission interferences. The BLE device compares the measured out-of-band RSSI with an out-of-band energy profile such as a LTE energy profile or a WiMAX energy profile to determine the out-of-band blocking signals indicating cadence or periodic out-of-band traffic activities. A remote BLE deice (advertiser) aperiodically or periodically transmits an advertising packet to the BLE device for a specific link layer connection. If not connected within a determined time period, the remote BLE device (advertiser) reduces transmission power for transmitting the advertising packet. The BLE device receives the advertising packet and sends a connection request packet to the remote BLE device (advertiser). |
