Astream - Buffer size limit

[alvinmb]

I'm using an Astream to read data from a bluetooth credit card reader and I get the following error in the log file. Does the Astream have a buffer size limit and if so what is it?


short form

Are you using AsyncStreams in prefix mode? This error usually happens when only one side of the connection uses prefix mode. You should change InitializePrefix to Initialize.
