I was trying to implement it but not much luck. Couple reason - 1 is not sure how to setup the xml on how to pass a character string.
B4X:
<method>
<name DesignerName="SendPronto">SendPronto</name>
<returntype>B4R::void</returntype>
<parameter>
<name>data</name>
<type>char</type> <----------------------- this needs to be a character array or string
</parameter>
<parameter>
<name>repeat</name>
<type>bool</type>
</parameter>
<parameter>
<name>fallback</name>
<type>bool</type>
</parameter>
</method>
Is it possible to add this routine to the library?
