How many packets are you receiving per second?

Example: if you receive 500 payloads per second, of 252 bytes each, that is 252*800*8bits / 1024 = ~788 kBit/s

Is that a change in nrf_esb.c? If yes; please revert that change.

Try setting the change in main, after init, but before starting the radio.

I put it in esb_init after setting all addresses just before return of NRF_SUCCESS.
But still no effect, 1000 packets per 1 sec. aproximately

changes this:
NRF_RADIO->MODECNF0 = (NRF_RADIO->MODECNF0 & ~RADIO_MODECNF0_RU_Msk) | RADIO_MODECNF0_RU_Default<< RADIO_MODECNF0_RU_Pos;

to this:

NRF_RADIO->MODECNF0 = (NRF_RADIO->MODECNF0 & ~RADIO_MODECNF0_RU_Msk) | RADIO_MODECNF0_RU_Fast << RADIO_MODECNF0_RU_Pos;

but actually nothing changes on speed...

NRF_RADIO->MODECNF0 = 1;

command like this right?
And where actually I need to set it, before ESB init or so?

Hi,

Try setting fast ramp up, field "RU" in register MODECNF0:

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/radio.html?cp=3_1_0_22_13_44#register.MODECNF0

Should be set on both sides, ie: the prx and ptx.

Cheers,

Håkon
