Hi, * I am reading through the firmware C codes and trying to figure out how to carry the RSSI values from auxiliary ADC in the word0 section of each ethernet frame. I was confused by the structure of the firmware C codes. In the main() of txrx.c, there is no explicit function calls looks like send(), recv() for handing the ethernet frames. And I found in mimo_app_common_v2.c some functions like send_reply(), set_reply_hdr() and handle_control_chan_frame() which may correspond to this issue. I also tried to modify the u2p_set_word0() function in usrp2_eth_packet.h in order to carry the RSSI value. But it seems that this only works when starting streaming as every frame rceived on the host side shows the same value. I really want to know how does the frameware handle the samples and controlling frames. Any hints?
Thanks in advance. Hanwen
