It turns out we don't really need the async in the transmit direction. If the blocking transmit turns out to be an issue, we can investigate async later. |

Fixes #140
To validate performance, I added a
PingandPongpacket types to the NET firmware, and logic to automatically respond to aPingwith aPong. It works reliably with the modified NET firmware flashed, though it's a bit finicky as to when in the lifecycle of the NET run you send thePing. I haven't gotten deep enough in the NET firmware to understand what's going on, but it's reliable enough that it seems like the basic UART logic works.There is a non-trivial conceptual shift here, in that
App::handleis nowasync. This works fine in theui-stm32crate, but is causing some trouble in theui-tauricrate (problems with holding locks on global state acrossawaitboundaries). As a result, the UART functionality is not currently implemented inui-tauri.
