Thank you, I was using SDK version 14.2. It worked when using version 14.0

Make sure that you are using SDK version 14.0. The patch is written for SDK 14.0

Hi John,

Thank you, I ran the example and it's straight forward.

Yes, I downloaded it but when applying the patch it seemed that some changes can't be applied !

Below the errors I got :

I don't use git often, soI'm not sure how to fix this ?

Thank you

Note that you need to use SoftDevice S140 version 6.0.0-6.alpha for maximum range. This version implements a range delay(packet time of flight compensation) corresponding to a distance of 5 km when using LE Coded PHY. You can download this version from here. The example John DeWitt mentioned(ble_app_att_mtu_throughput) is the best for testing the range. You can find a patch in the S140 version 6.0.0-6.alpha zip for the ble_app_att_mtu_throughput example, making it compatible with the S140 version 6.0.0-6.alpha.

Hi Chaabane,

You might want to start by looking at the through put example, it will allow you to choose the 2M, 1M or coded Phy as part of setting up he test. You can find it in the SDK folder hierarchy here for example: nRF5_SDK_14.2.0_17b948a\examples\ble_central_and_peripheral\experimental\ble_app_att_mtu_throughput

Hope this helps, JD
