Hi,

That's odd. Maybe you could access it from here. https://www.nordicsemi.com/Products/Development-software/nRF5-SDK/Download

Go to "Documentation" -> "Hardware drivers" -> nRF 52833 Drivers -> "Radio HAL" -> nrf_radio_preamble_length_t

Hope that helps!

Hi,

Our hardware solution cannot achieve that as it is not conformant. See https://docs.nordicsemi.com/bundle/ps_nrf52840/page/radio.html#concept_hz4_cjl_4r__fig.packetonair for more details.

Hi,

Thanks for your answer, but however can I modify it?

I would like to set it to 0x42.

Thanks.

Hi,

By definition, the preamble is a fixed sequence of alternating 0 and 1 bits. Therefore, values like 0x41 or 0x42 do not meet this criterion. Could you please provide more details about your question?
