Android Question astreams-how do i clear a buffer

[FFMan]

I'm using astreams to receive data over a Bluetooth link.

If the comms gets out of sync I need to clear the buffer, before I send another request for data. but I can't see how to clear the buffer, the astreams_newdata only fires when new data is received, if there is data in the buffer I want to discard how can I read this ?

thanks

I never clear the Buffer. I use

b = b & BytesToString(Buffer, 0, Buffer.Length, "UTF8")

, then use IndexOf and SubString2 to parse the string, to pull out commands to process, and to clear used part of string.

I think I get characters in the buffer when the app pauses and resumes, or when I kill and restart it, so there are characters in the buffer but the event doesn't fire. I need some way of clearing the buffer before I request new data, otherwise I guess I could code in a dummy request that causes a dummy return to fore the event.

just wondered if there was an easier way.

Have you tried setting Buffer.Length to zero?

When possible, I like to use a protocol, to give identity to the request, and reply. It helps sort the handling for various processing needs.

There is no buffer in AsyncStreams (unless you are using prefix mode). The events will be raised when the activity resumes.

I recommend you to use a service to manage the communication. It will be simpler.
