DESCRIPTION
While working on Votsh Waves using Pinoccio technology and Atmel's LightWeight Mesh (LWM) radio network technology we found technology choices that improved network transfer speeds.

Votsh Waves
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
VOTSH
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
