We are looking for BLE module for Social distancing application.
We want to use Only BLE tags to estimate relative distance with respect to nearby tags within 5 meter range.
Please confirm whether this is feasible using Nordic BLE chipset/module. also please let us know what level of distance accuracy we can achieve.
Kindly suggest suitable BLE module. ( key factor for consideration – Low BOM cost, Low power consumption, consistency and accuracy in distance measurement)
Also plz let us know if there is guide or case study document available for this use case.
