RE: Testing BLE-LR using nRF52840 DK Boards

If you have two (or more) DKs available I suggest taking a look at our Testing Long Range blog post, which explains in detail how you can check the performance of Coded PHY versus the "regular" 1MBPS PHY using the DKs.

It's hard to say how much better the performance of a Coded PHY application will do in an indoor environment, as there are many factors affecting a connection in, for example, an office environment. As you can see, we were able to achieve ~two times the range using Coded PHY outdoors in an open environment with little to no interference at 0dBm. This performance will be affected by the antenna and board in your final design as well but should give an indication of what to expect at least.

Best regards,
