7. A tire pressure monitoring system comprising:
an electronic control unit (“ECU”) configured to transmit or receive a first Bluetooth Low Energy (“BLE”) advertising event at a Phase Auto-Location (“PAL”) block associated with the ECU; and
a processor configured to generate a random number to be used for an inter-event delay associated with a BLE system, wherein the inter-event delay includes a fixed time and a randomized delay, wherein the processor is further configured to calculate a time for the randomized delay and to add, using a processor, the time to an encoded Look Back Time (“LBT”) from the first BLE advertising event to generate frame contents, wherein the processor is further configured to provide the frame contents and the random number to a stack for transmission, wherein the processor is further configured to receive a scan request from the vehicle ECU to provide an inter-event delay, and wherein the processor is further configured to transmit the inter-event delay in a scan response to the vehicle ECU, wherein the scan response occurs without modifying frame contents between transmitted frames.
