The Bluetooth connection is bidirectional so conceivably that can be done

I don't know if the SPP profile supports it though

Give it a try

I assume you would do a textreader

I haven't done it so I cannot really say

Do you perhaps know how to do a textreader?

my mobile printer (p25i) has a credit card swiper.
Anyone could give a hand for this?

No I just got the printer and just realized it had a credit card swiper. I'm able to print (text only). I'm pretty sure reading wont be a problem, just gotta learn how to listen :/

try the demo/sample program that they have included to make sure it will read and everything is working

presumably the reader is an input device and you would use an input stream to read it

I have never done it - try some things - if they work let us know

It worked.

B4X:

cmp20 is Serial.

Dim inText As AsyncStreams      

inText.Initialize(cmp20.InputStream,cmp20.OutputStream,"inText")
      

Dim th As String
th = BytesToString(Buffer, 0, Buffer.Length, "ASCII")

Just make sure the device is connected and it will read it.
I recieve 3 seperate packets from time to time. Is there a way to wait for all data to be received instead of fetching new data one by one?

What are you receiving?

The AsyncStream has a stream finished event does it not?

I'm not too familiar.

B4X:

B45********885^C    /BRYANNE^20*******000000?
;45*********85=20********274?

It has CreditCard data so I **** it out.

A small note: you would need to be connected to the device, see the forums on how to or send me a message !

CountingInputStream is not asyncstream. So I cant use the stream finish :/ do they work the same?

For a very nice but really cheap printer check out these guys

http://rongtatech.com/

I get the RPP-02N model from Jeff for US$39 each

I have very satisfied customers - I just ordered another 20 units (already had 42 units from two previous orders)

THis printer RPP-02 can print with ESC/POS commands? I worked with something like that and I cant use the ESC/POS from B4A but I use another app and this it can.
