Can NRF52840 in Long Range mode communicate with BLE devices in non-Long Range mode?

[cory123]

And a related question... can NRF52840 in long range mode pick up advertisements from further away BLE device which are not in long range mode?

Hi

Yes, a scanner configured to scan the Coded PHY will also see "normal" advertisements, as Coded PHY requires the use of extended advertisements, it must first be discovered on the primary advertising channels before reading the advertising data on the secondary channels, so it will see the initial advertisements of "regular" advertisements as well unless you filter these out somehow. I would suggest checking out this NovelBits blog post on Coded PHY over BLE. 

Best regards,

Simon
