[Tinyos-help] receiver throughput

[Vijay Gabale]

Hi there,

I am currently employing tmote sky platform mote to carry out some
experiments with tinyos 1.x.  On transmitting packet from mcu to radio tx
fifo over SPI, I could get maximum of 270 kbps of throughput but on
receiving packet from radio rx fifo to mcu over SPI, I observed that, the
throughput was around 145 kbps. I explored HPLCC2420M.nc to realize that
whenever you need to fetch a byte from radio fifo, you first need to
transmit a signal to radio. This effectively reduces throughtput while
receiving over SPI to half of that of transmitting. CC2420 data sheet does
not mention about this asynchronous fetch.

Has anybody encountered and tackled the same problem? Can we have solution
to this?

Vijay.
