Re: [Discuss-gnuradio] USRP N210, sometimes, cannot receive packets

[Jeff Long]

How are the clocks in the N210s synced? What rates are you using? What symptoms are you seeing that tell you the sinks are not receiving packets?

Hallo guys,

I have a configuration using gnuradio-companion as follows;

#########              #########              #########

# sink_1 #  <- - - - -  # source #- - - - - --># sink_0  #
#########              #########              #########

The devices I am using are USRP N210s and it is with SBX daughterboard and without GPSDO. The distance between the nodes is 1 meter. I use BPSK Modulation to transmit the packets and the frequency is 2.485 GHz. I would like to broadcast packets from source to sink_0 and sink_1. One of the sink can receive the packet but the other one hardly can. In 10 times run of the program, both of the sink can successfully receive the packets only 1 or 2 times. Most of the run, only one sink can receive the packets. Moreover, If I disable one of the sink and run of the program to transmit the packet from source to sink. In the 10 times run, the sink can receive it only 5 or 6 times. There are 4 times it fail to receive the packets. I have known yet where is the problem. Any suggestion would be helpful.

Thank you in advance.

Best regard,

Kirianto
