Updated the app to work with the nrf52DK Uart Precompiled Sample

[AllyTechEngineering]

The code as is will not connect (after you update the code to the current flutter version). I assume others have worked on this. The one key area is that the nrf52 code has two characteristics so you need to use the servicesWithCharacteristicsToDiscover to make it connect. I have not take care of the overflow for the persistentFooterButtons area. In the short term I made the font smaller. Ran on my iPhone 14 Pro and you can see the screen shot. Here is the main problem:

original code: // _currentConnectionStream = flutterReactiveBle.connectToAdvertisingDevice( // id: _foundBleUARTDevices[index].id, // prescanDuration: Duration(seconds: 2), // withServices: [_UART_UUID, _UART_RX, _UART_TX], // // withServices: [_UART_UUID], // ); Updated code - works: _currentConnectionStream = flutterReactiveBle.connectToDevice( id: _foundBleUARTDevices[index].id, servicesWithCharacteristicsToDiscover: {_UART_UUID: [_UART_RX, _UART_TX]}, connectionTimeout: const Duration(seconds: 2), );

I did not clone the work so not sure if someone else has fixed this? I can put in a link to my github if you would like.
