RSSI vs TOA for calculating distance - Can LoPy4 Support TOA?

[gt2rs]

I am currently using Pycom (LoPy4 modules) to calculate distance between each module - there are 3 modules setup as static reference points(1 as base station and 2 as referance points to base station) and 3 additional LoPy4) as moving terminals. I have setup communications using Lora and I am using RSSI to calculate the distances. Despite using various standard Multi-Path algorithms I am still getting large distance differences as my setup is on 100m radius and some devices are non line of sight and outdoors. Can LoPy4 support TOA for distance calculations and will this be more accurate - Any assitance on how to setup TOA will be gladly appreciated.

You can't use TOA I think with any PyCom hardware.
