How to send Carriage Return over nRF Toolbox UART Buttons?

[Cavemanatwork]

Hi together!

Ist it possible to send a CR (Carriage Return) over the programmable UART Buttons? When yes, what is the Syntax for?

For example, i need to send such a string: 58796541[CR]

Thank you very much and best Regards Michael from Germany

Ok, done. The app has been published on Play and the source code is now available on GitHub. You may also download the APK from there.

Since 1.16.4 this is no longer required. You may select the EOL type when you configure the button. Remember to add a new line to your command at the end of the line.

Hmmm? i think it doesn't works. Whatever i choose, my Oszi always shows me a LF.

Could you post here screens from the app (command dialog and the log after sending the data)?

Here is the trick to add " in the "nRF Toolbox" UART application for smartphones:

1. First - the Configure button text fields for editing the button data in the nRF toolbox app are multiline! Just press enter in the text field to make as many + pairs you like.
2. Secondly the EOL option [LF, CR, CR+LF] in the UART Configure button dialog act as a FILTER. For the filter option to work you first HAVE to add linebreaks to the text field.

Not so intuitive - as you may first think the UART app button command option selects what characters to append.

The second image displays a linebreak added in one of the the UART, Configure button text fields.
