Greetings....
It is great that you provided SDK UART coexistence example for nRF5 SDK for Mesh v3.1.0 and nRF5 SDK v15.2.0 release for Client node with nRF52832 DK. However, I am sorry to say that we don't have a similar one for the Server node since for nRF5 SDK for Mesh v3.1.0 and nRF5 SDK v15.2.0, because the Friend node implementation was done by using Zephyr binary.
Since SDK UART coexistence example for nRF5 SDK for Mesh v3.2.0 and nRF5 SDK v15.3.0 release for Client node is no longer working, will it be possible for you to restore it for this latest release. Now that Server node also implements Friend feature, will it be possible for you to add this into your SDK UART coexistence example as well for both nRF52832 and nRF52840 DK?
This may greatly help us the beginners in understanding the complicated Mesh environment and better use your BLE products!
Thank you so much for your consideration!
