Calculating timestamp of thingy 52 scanning the data from another thingy 52

[manish_tyagi]

Hi folks, 

I want to calculate the timestamp for which my thingy 52 board was scanning from another thingy 52(may be more than one board). Is there any technique to get the time of scan based on the proximity condition.

condition: If distance b/w boards are < 2 mtr.

PS: It may contain hundreds of devices(thingy).

Hi,

I am not sure I understand what you want to do, but you could get a timestap based on the RSSI measurements when scanning for devices, but RSSI is not a recommended method for accurate distance measuring...

Hi msromero,

Thanks for your reply. I want to further know how can we get the timestamp using RTC(Real Time Clock). Do we need to add the external RTC for nordic thingy 52 board? 

I am using the RSSI concept to calculate the distance and want to add timestamp for the time the things boards are in contact with each other within specific distance.
