B4J Question Understanding Asyncstreamsobject

[HARRY]

I need to send from an Arduino structures to a Raspberry receiving those structures as types, and handling the received stuff using B4XSerializator. I understand that on the Raspberry I should receive those structures/types as objects. I tried it, but received an error message that the length was too great.

What should I do on the Arduino side to adhere to the requirements of Asyncstreamsobject on the Raspberry. The traffic is only in one direction: from Arduino to Raspberry.

1. There is no reason to use AsyncStreamsObject at all. You should use B4XSerializator instead.

2. Ignore point #1 when you communicate with Arduino and use B4RSerializator instead: https://www.b4x.com/android/forum/threads/72404/#content

ad1: So I should use AsyncStreamsText?

ad2: I assume that the received stream on the B4J side should contain information on the layout; at least on the length of Strings contained in that stream. What is the layout of that information? I must compose a stream on the Arduino side which B4J understands, shouldn't I?

You need to use B4RSerializator if you want to communicate between a raspberry pi and an Arduino. You can see the format in the source code: https://www.b4x.com/android/forum/t...ceive-objects-instead-of-bytes.72404/#content
