Set up FDD independent mode

AD9361, no OS library

I want to use the FDD independent mode to switch on/off the TX chain while receiving continuously.

How can I setup the FDD independent mode in the init structure? And what do I have to do after the init function?

I have set the frequency_division_duplex_mode_enable and frequency_division_duplex_independent_mode_enable bits.

After that I do  ad9361_set_en_state_machine_mode(ad9361_phy_a, ENSM_MODE_PINCTRL_FDD_INDEP);

But the RX/TX chains work only if I pull up the ENABLE / TXNRX signals before executing the init function.


Edit: When use ad9361_get_en_state_machine_mode after the procedure, I find that the ENSM is actually in ENSM_MODE_WAIT.
