we were been facing problems in throughput of CC2530 as it is TI MAC and Zigbee stack ,typically the data rate is maximum 250Kbps and hardly we are getting a throughput of only 50Kbps as out network involves voice streaming through multiple nodes,so i have seen CC2545 with higher data rate about 2Mbps which could rescue us,but now our problem is TI MAC is only available for CC2530
what to do if i need a MAC for CC2545 ? are there any thirdparties who are giving MAC needed for CC2545
if a MAC is available we can afford to write our own datalink layer bypassing zigbee,i need some suggestions on this from experts
