Hi Troy,

Are you unhappy with the range of one of TI's development kits (CC85xxDK or CC85XXDK-HEADSET) or your own boards? Are you using the CC85xx + CC2590 (range extender)?

Hi, Jim

I am very happy with the range of CC85xx+CC2590.

Our customer require the auto-pairing of two audio devices when they are close enough, so I want to known if there is method to known the distance of two RF devices.

Thanks

Troy,

You have to run the slave in host controlled operation (needs an external MCU), and perform NWM_DO_SCAN repeatedly. This method lists information of up to 8 networks, including the average RSSI value of the packets received from the masters (the masters must have the network enabled). If the master runs in autonomous mode the network is enabled whenever the master is on. If the master is host controlled you must perform NWM_CONTROL_ENABLE on the master. You can then join a network (NWM_DO_JOIN) if the RSSI value is above a certain value.
