Hi
I have nRF52840 DK with nRF5_SDK_17.0.2_d674dde
I am using radio_test example code under examples\peripheral\radio_test:
Radio Channel is fixed at 10,
The data packet is : from x01 to 0x1F
20 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F
Normally, it is ok, but occasionally, it received with a bit error:
uart_cli:~$ print_rx
20 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
10 11 12 13 14 15 56 17 18 19 1A 1B 1C 1D 1E 1F
My question is: radio receiving is when CRCOK event occurs,
nrf_radio_int_enable(NRF_RADIO_INT_CRCOK_MASK);
void RADIO_IRQHandler(void)
{
if (nrf_radio_event_check(NRF_RADIO_EVENT_CRCOK))
{
nrf_radio_event_clear(NRF_RADIO_EVENT_CRCOK);
/ / data packet recieved here
m_rx_packet_cnt++;
}
...
}
Why the packet is still received when there is CRC error? I believe that data byte 0x16 is changed to 0x56, CRC must be different.
Did I miss something here?
Thank you,
David Zhou.
