Testing BLE-LR using nRF52840 DK Boards

[justNordic]

I have two Nordic nRF52840 DK Boards and I need to check the performance of BLR-LR i.e. how much range do I get in Indoor Environment and in Open Environment.

Can someone please suggest any example that can be used here ? Should I start with the folloiwng:

nRF5_SDK_16.0.0_98a08e2\examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput

As of now, I'm looking for quick and easy way to test BLE-LR so that I can decide if 810/832 is good enough for my use case of I need to go for 811/833.

Hi

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,
