Star-Dust,
The example you made is so fantastic.
Thank you
It settled the problem I was having with FCM.
Please can you tell me how to send an
Image - from
Phone to Desktop - using the same MQTT method.
You said about adding a Transmission Protocol:
how can I connect a mobile device via usb cable or wifi without necessarily having servers or similar. I would like to send messages through the messaging apps installed on my phone
Please show me how to integrate into your example B4A and B4J Apps.
Thank you so much again
