what is the maximum data rate that can be achieved by RN-131? with on board antenna, i could only send packet of 489 bytes[maximum](with on second delay), when i made packet of data above than 489 bytes, loss of bytes occured … only 489bytes/second is too slow…
I don’t know what the max is, but we were pushing out 1420 bytes per packet using UDP at a little more than 6 packets per second.
This was for a custom design using an LPC1756 as the controller gathering continuous data.
did you face missing of bytes during reception of data from wifly module(transmitter) to wifi_enabled_PC(server, receiver).??
Are you usiung UDP or TCP? I routinely send large amounts of data using TCP at rates above 10KBytes/sec. You may need to change some the parameters you have set. From the WiFly manual:
The UART receive buffer is approximately 1,500 bytes. At lower baud rates (less than 115 K), the system can send data over TCP/IP without flow control.Depending on the frequency and quantity of the data being sent, the comm parameters optimize Wi-Fi performance by specifying when the system sends IP packets. To minimize latency and TCP/IP overhead, use the flush size or match character to send data in a single IP packet. In most cases, you should set the flush timer to a large number to avoid fragmentation. For high throughput, increase the UART baud rate, set the flush size to 1,460, and set the flush timer to a large value so that full IP packets are sent.
