compile error of bluetooth esb ptx sample

[idan.bismut]

I cannot get the esb ptx sample to compile on NRF52833 device when using VS Code v1.64.2 running windows 10 64bit .

I've installed everything according to videos, and when attempting to compile the Bluetooth sample, i'm getting the following error:

In file included from C:\Users\idan.bismut\ncs\v1.9.1\nrf\subsys\esb\esb.c:10:
C:\Users\idan.bismut\ncs\v1.9.1\nrf\include\esb.h:122:24: error: 'RADIO_MODE_MODE_Nrf_250Kbit' undeclared here (not in a function); did you mean 'RADIO_MODE_MODE_Nrf_2Mbit'?
  122 |  ESB_BITRATE_250KBPS = RADIO_MODE_MODE_Nrf_250Kbit,

      |                        RADIO_MODE_MODE_Nrf_2Mbit

how do i fix this one ?

I am not sure which example you are referring to, however there is no proprietarty 250kbps mode on the nRF52833.

Looks like the ESB library have some define that include 250kbps (likely for legacy reasons), but this is not supported. I suggest to comment out ESB_BITRATE_250KBPS from nrf.h or just set is to (default) ESB_BITRATE_250KBPS = RADIO_MODE_MODE_Nrf_1Mbit (then it will at least compile, just make sure not to use it, since it's not supported).
