You shouldn't have to make any changes to the SoftDevice in order to make it compatible with nRF52811, as it is already compatible. For general guidelines on how to develop projects for the nRF52811, please check out our user guide on the matter, where you can see amongst other things, how to make an nRF52840 example project (with the S140 SoftDevice) compatible with nRF52811 hardware.

Best regards,

Simon

Thank you for your reply,

I thought "S140" only supports 52840...

I have a question

I don’t know how much code need to be changed to make S140 support 52811?

Thank you

The reason long-range (Coded PHY) is not supported on SoftDevices S112 and S113 is mainly that Coded PHY depends on data length extensions, which in and of itself is a rather large feature taking up a lot of space. Secondarily, Coded PHY is not a very widely used feature, partly because it has limited support on the phone side as of yet (only the newest flagship models are actually supporting this as of yet).

If you take a look at the nRF52811 compatibility matrix, you can see that it does support SoftDevice S140, which is the SoftDevice you'll have to use in order to use the Coded PHY feature.

Best regards,
