microbox Active Member Licensed User Longtime User Sep 3, 2021 #1 Hello everyone, I need the simplicity of MQTT for a chat app. But I also I need the option to be able send file to a specific user online. Can you give an idea what is the best way to achieve this? I have tried using the example (Network + AsyncStreams + B4XSerializator) transferring file is working but I 'm having trouble reconnecting to other user(max 5) to send message.(always disconnecting). I appreciate any help.

The file is less than 4mb, is it the similar to Network + AsyncStreams + B4XSerializator? Can you please give a link/snippet incorporating MQTT? Upvote 0

DonManfred Expert Licensed User Longtime User Sep 4, 2021 #4 No. I do NOT see any problem here too. Convert the file to a bytearray and send this bytearray. As far as i know MQTT is able to have binary payload. What about writing 5 Lines of code by yourself? Upvote 0
