TIFS register to delay two consecutive TX packets

[saugatlogic]

Hello, 

I am trying to send two consecutive packets through NRF_RADIO with a fixed delay in between them. According to the specification there is TIFS register if set would delay the TX and RX packet and one of the devzone post also stated it is possible for two TX packets. I currently have the following setup with the short on END_DISABLE and DISABLED_TXEN, and have a defined the interspace register to 250us. But, in log it shows that the difference between consecutive READY and END signal is just 60us. 

nrf_radio_ifs_set(NRF_RADIO, RADIO_INTERSPACE_DELAY);
nrf_radio_shorts_enable(NRF_RADIO, NRF_RADIO_SHORT_READY_START_MASK |
                                           NRF_RADIO_SHORT_END_DISABLE_MASK | NRF_RADIO_SHORT_DISABLED_TXEN_MASK);

Thank you in advance.

Hi,

You could have a look at radio mode configuration register 0 - MODECNF0. When this register is enabled, TIFS is not enforced by hardware and the control of turning on the radio is done by the software.
