Regarding the hardware triggering in HackRF

[swapnachallagundla]

What would you like to know?

I am trying to synchronize two HackRFs with two GPSDOs separately. The two hackRFs with GPSDOs are placed at different locations. I have connected 1pps to the sync_in pin on p28 interface and connected 10MHz to the clockin port of HackRF. The clock is detected on clockin port. And I am including -H command in hackrf_transfer to enable hardware triggering during recption of the signal. Even though i have included all these I am getting the delay in milli seconds between the signals recorded by two hackrfs simultaneously. Actually it should be in micro seconds as the two devices are synchronized with 1pps.
What could be the problem?

Hi @swapnachallagundla,

I've just written up a checklist in issue #1386 to help with synchronisation problems, because there's a lot of ways it can go wrong. Could you have a look through that checklist and see if it helps diagnose your problem?
