Android Question B4A BT_Printer - How to print from code module?

[mmanso]

Hi all,

I'm using Star-Dust's BT_printer library to print to a bluetooth printer.

I've declared:

Dim Printer As BT_Printer

in Main's Globals section.

Everything is working, I connect to the printer I want, all this in Main Activity.

In the same project I've a service that calls a code module that starts an HttpServer that has an Api to accept print commands from remote machines...

My question is, being that server implemented on a code module, how can I use the Printer defined on the Main activity?

Thanks.

You tried passing the Printer variable as a parameter to the service.

You can also try to declare the Printer variable in the Starter service module and get it from the activity or other services

I tried, but I get this warning from the IDE

You tried passing the Printer variable as a parameter to the service.

You can also use the Call command in the service to invoke methods of the activity where you enter printer commands.

Thanks... didn't remember about the CallSub (I'm new to B4x).

Will follow that route.

Thanks.
