Is it possible to share your current synchronisation code?
I'm very intrested in RX-TX synchronisation

Give the current master code a try and be sure to set the appropriate samplerates before configuring the synchronous sample stream.

Also note that you want the META sampletype.

Check the samples in the documentation.

Hi,
I'm new to the BladeRF. But, working on an FMCW radar and need the right delay between RX and TX. Is this achievable now - Synchronous RX-TX? If yes, appreciate if anybody can share the method. I'm running using simulink and getting random rx time even in loopback mode.

Dear all,

I found this topic very interesting. I tried to follow the timestamp issue but I hit a wall. Mostly based of my lack of expertise in this matter. Attached is a GNURadio block diagram I made. All works well with the exception of TX/Rx sync. Anybody have a hint for it? Thanks in advance.
