From Nordic: "Interactive console in Smart Remote 3 for nRF52 Series"
Do you want to learn about new possibilities of automated testing of your products? Would you like to have the option to debug different configurations of your firmware without recompilation? The recent release of Smart Remote 3 v1.2 features an interactive console. The console is a powerful tool that lets you add you own commands to the firmware, giving you profound insight and runtime control over the device. You can connect with the console using Bluetooth Low Energy, UART, or RTT. Our video shows an example of how you can use the console for runtime reconfiguration of the Opus audio codec and testing the range and bandwidth of audio transmission over Bluetooth LE.
