I am trying to use the WiFi library with Galileo and I'm seeing a delay of about 1 or 2 seconds when I call WiFiClient.available() and there is no data available on the connection. Here is the code I'm using after establishing a connection:
| Code to Read from Connection |
|---|
WiFiClient g_client = server.available(); if (g_client) { if (!g_client.connected()) { Serial.print("Closing client connection...\n"); g_client.flush(); g_client.stop(); } else { Serial.print("Connected to client!\n"); int numBytes = g_client.available(); Serial.print("Bytes Available: "); Serial.println(numBytes, DEC); if (numBytes > 0) { Serial.print("Reading from client...\n"); // read the bytes incoming from the client: char thisChar = g_client.read(); Serial.print("Received: "); // echo the bytes to the server as well: Serial.println(thisChar); incomingByte = thisChar; } } } |
The call in blue above takes about 1 or 2 seconds if there is no data. If there is data, it returns right away. (My client is sending 1 character on each send by the way.)
Any ideas why there is a delay? I don't want the loop in my sketch to have that delay when there is no data from the client.
