One more thing might be interesting is that the nRF52840 has a low speed mode with better sensitivity: -103dBm sensitivity at 125kbps BLE vs -96dBm of the nRF52832 at 1Mbps. Also +8dBm max output vs +4dBm of the nRF52832.
That 7dBm receive sensitivity increase theoretically should double the range.
Has anyone tested, or has data on potential range improvement (preferably inside a building)? Nordic has published pretty impressive range outdoors...
Is there any gotcha? Other than there is no support for Bluetooth 5 on either my phone or laptop & I have no idea about the intricacies of Bluetooth versions....
