B4R Question Buffering to transmit data...

Are you using ESP8266? The data is buffered automatically. It is sent when you call Flush or on the next message loop cycle.

Dear Erel,
Indeed I am using ESP8266. I want to sample an analog signal say ECG and send it across Wifi. The values take a long to reach the destination, hence I want to send a chunk of data at a time but unable to figure out how to do it!

Are you using AsyncStreams? If so then the data is already buffered.
