Network Transfer Rates Are Important

LightWeight Mesh Radio Network

LWM Network Speed

K Bits Per Second Issue

0.6 Acknolwedgements “on”, 250 K bits/sec rate, sending messages > 1000 milliseconds, 50 character messages

5,200 Acknolwedgements “off”, 75 character messages, Sending messages > 250 milliseconds

90,000 Acknolwedgements “off”, 100 character messages, 1,000 K bits/second rate, send as often as possible

1 Megabyte Audio File in 1.6 Minutes

Solutions• Hit the LWM Send as often as possible

• Turn off acknowledgements

• Crank up the transfer rate from the default 250kb/sec to 2Mb/sec • EEPROM_writeAnything(8126, transferRate );

• Use unicast or broadcast, not multicast
