Social distancing example Range Setup

Hi Dialog support,

With your social distancing example i am able to get an danger alert when device is 1.2m apart each other. It is giving accuracy only for 1.2 m.

Which parameter i need to configure to acheive configurable range between two devices like 2m or 3m?

Thanks

Device:
DA1469x

Hi rohitkr.5293,

Hi rohitkr.5293,

Thanks for your question. I assume that you are use our DA1469x device, so I’ll change the initial device selection (DA14580).

You can change the danger alert threasholds in the distance_sw_fsm.c file. That file holds all the available configurations. Please check the DFLT_DANGER_ZONE_DISTANCE_LIMIT, DFLT_DANGER_ZONE_RSSI and NUM_OF_DANGER_ALERT_BEEPS macros.

Before using the STD example, please checkout the Manufacturing considerations :

Hi PM_Dialog,

Hi PM_Dialog,

Thanks for your reply.

After modifying range it to 2m, there is still no accuracy. How we can get accuracy after changing it to 1.2m to 2 or 3m?

Also how we can calculate the Distance Offset trimming for our custom PCB layout?

Thanks,

Rohit
