Android source code to communicate via BLE to modify for my application

[jerry]

Hi I have a product that uses an Nrf52810 in a Raytec slave module. I am able to successfully send and receive packets of data using  your UART app in the nrf Toolbox

I would like to develop a custom Android phone app using a Windows 10 PC, as a cross compiler.. What source code should I download from Github and what platform does it run on(Android Studio or VS?)

Basically I need a driver for the communications in order send and receive data. ,

Thanks

Jerry

Okay so, I read that the UART app is not being supported any longer, so I tried The Nordic Toolbox. It runs and loads into the phone but when I try to connect the app just shuts down. I read that it would be simpler to start with the blinky app as it's simpler. When I try to build that I get this error...

• Cause: android.defaultConfig.versionCode is set to -1, but it should be a positive integer

How do i fix that?

Hi,

Did you resolve this? I am no Android developer, but looking at the code I wonder if you download the files instead of checking out the git repo? I expect that would cause problems as versionCode is set to getVersionCodeFromTags() in build.gradle, and that only works within a Git repo.
