Android Question Bluetooth example t (CRLF) his is a test

[Beja]

Hi all,
did anyone experienced this or only I.
Running Bluetooth admin example, sending text from device to PC is ok.
but when I sent "this is a test" from PC back to device, it was displayed like this:

t
his is a test.
any explanation?

BUT:
When I made a space before the sentence:
this is a test, the result was normal

Are you using prefix mode (see AsyncStreams tutorial)?

 

[Beja]

no prefix..
Now I added a space and sent " this is a test" and the result was
:
: this is a test.

So the space resulted in a CRLF then the complete sentence without a space. This means to me
that the incoming data is coming like this:
1- the first character whether it is a letter or a space
2- CRLF
3- the rest of the string

example 1:
I send "testing". the result is:
:t
:esting

example 2:
I send (Space)testing. the result is:
Space)
:testing

You should not assume that messages sent from the PC will arrive as a single message on the device. This is exactly the purpose of prefix mode.

However if you cannot use prefix mode then you can use AsyncStreamsText (assuming that each message ends with an end of line character).
