Device match

[fangrui166]

uint8_t base_addr_0[4] = {0xE7, 0xE7, 0xE7, 0xE7};
uint8_t base_addr_1[4] = {0xC2, 0xC2, 0xC2, 0xC2};
uint8_t addr_prefix[8] = {0xE7, 0xC2, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8 };

i want to triger a interrupt via PPI when received package from pipe 2 ( 0xC3 0xC2, 0xC2, 0xC2, 0xC2). so how can I config DAB , DAP and DACNF registers ?

my PPI init like below, if it is correct ?

nrf_drv_gpiote_init();

nrf_drv_gpiote_out_config_t config = GPIOTE_CONFIG_OUT_TASK_TOGGLE(false);
nrf_drv_gpiote_out_init(LED_4, &config);
uint32_t gpiote_task_addr = nrf_drv_gpiote_out_task_addr_get(LED_4);

NRF_RADIO->DAB[?] = ?
NRF_RADIO->DAP[?] = ?
NRF_RADIO->DACNF |= ?

NRF_PPI->CH[NRF_ESB_PPI_POS_SYNC].EEP = (uint32_t)&NRF_RADIO->EVENTS_DEVMATCH;
NRF_PPI->CH[NRF_ESB_PPI_POS_SYNC].TEP = (uint32_t)gpiote_task_addr;
NRF_PPI->CHENSET = (1 << NRF_ESB_PPI_POS_SYNC) ;

nrf_drv_gpiote_out_task_enable(LED_4);

maybe DAB. DAP need to fill into MAC address .
so if PTX's MAC address is as below:

NRF_FICR->DEVICEADDR[0] = 0X01234567

NRF_FICR->DEVICEADDR[1] = 0X89ABCEF0

what's the value of those registers?

It is correct that the 48-bit BLE address is derived from the DEVICEADDR register in FICR. This is done in the SoftDevice, and not directly related to ESB. The “device address” is not the same thing as the on-air radio ADDRESS field(which is composed of the base address field and the address prefix field.). The device address is something you need to generate and add on your own in the payload part of the packet. (only if you actually need to use the device address match feature for white listing)

Note that you will get a radio address match event(EVENTS_ADDRESS), if the address is correct. Maybe this is what you are actually looking for ?

yes, and I'm base on ESB.  and my code is base on "nRF5_SDK_11.0.0_89a8197\examples\proprietary_rf\esb_prx (esb_ptx)"

So ,can you help me that what the value of those registers should be ?

and what's the payload I need to send ?

and any other need to change ?
