The RFX (FLEX) series of transceiver daughtercards include an onboard T/R switch to allow a half-duplex setup using the Tx/Rx connector and a single antenna.
In GnuRadio 3.3.0, under GRC, the choices for the "Transmit" parameter on a USRP Sink Block seem to be limited to "Unconfigured", "Enabled", or "Auto T/R". Since my application continuously produces transmit data, even while idle, I want to be able to manually control the T/R switch from an external entity, probably via a GRC variable that is set from a message source or UDP source. Is this even doable? GRC's block parameter editor does not show this parameter as underlined, meaning it cannot be changed dynamically. Would it be possible to dynamically control the transmit_enable by calling the appropriate method using a probe block? Although this application is locked into using GR 3.3.0, I've also looked at the GR 3.5.1 xml description for a GRC UHD_sink block, and can't even find where the transmit enable is. Any help on this? @(^.^)@ Ed _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
