Just a heads up, but Michał was working on adding RTT console support for Mynewt and with those patches it should be possible to disable UART_0 ie. we are able to use console over RTT while using UART for HCI monitoring (other feature we are working on). Currently this is pending review and PR should be updated in upcoming days. Code is available at https://github.com/michal-narajowski/incubator-mynewt-core/tree/bletiny2 -- pozdrawiam Szymon Janc
