Hi All

remote device far from raspi. about 150meters I used RS485 converter point to point (there are one raspi and there ara one remote device
and baudrate 1200

a-) send query string on jerial and AsyncStreams all ok, receive time to time 5 or 6 bytes also I need 18 bytes. I thing newdata event rising first 5 or 6 bytes (some times 2 or 3 bytes)
b-) how can I pullling input stream amount to byte size ?

You should assume that network messages will be split or merged.

The NewData event, in non-prefix mode, is raised whenever there is data in the incoming buffer.

If you are working with text protocols then you can use AsyncStreamsText: https://www.b4x.com/android/forum/t...eful-when-working-with-streams-of-text.27002/
