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

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.
