B4R Question [Solved] How to remove Control Characters with HC-05 and readstring

[Yayou49]

Hi,

Using a nano and a HC-05 module, when in B4A sending a text with :

Starter.Manager.SendMessage("Hello") 'BluetoothManager

In arduino Serial Monitor, when receiving data (readstring), I can see some control characters.
I don't know how to remove them.

In the same time, if I try to use

Serial.println(Data.indexOf("Hello"))

, return is -1. Like if "Hello" is not reachable.

My final goal is to catch the message and plug different functions according to the value.

Any idea ?

Any idea ?

You are most probably using prefix mode in one of the sides only. Best option is to initialize AsyncStreams in prefix mode in both sides.

Problem solved with

AStreams.Initialize(Main.Serial1.InputStream, Main.Serial1.OutputStream, "AStreams")
