Hi

Now I am using the kw36 development board to participate in a Bluetooth Car project. I want to use Bluetooth to measure the distance between two boards. If I don't want to use the RSSI attenuation formula of field strength, but I want to use Bluetooth as the transmission speed of electromagnetic wave to be constant, and use TOF (time of flight measurement) method for ranging, has anyone tried to write the relevant development program with Bluetooth through kw36? If not, does NXP have a similar TOF ranging routine? I hope some engineers who have seen similar programs can help me to provide a routine. Thank you very much.
