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.
