nrf52 reconfigure PACKETPTR on address event in continuous receiving

[jane_song]

Hi all,

  I use nrf52 for continuous receiving when enabling the shortcut of END_START.We know when the shortcut of END_START is enabled,the radio start task is triggered without CPU after the end of last packet and  there is no time for us to reconfigure the  PACKETPTR.So I reconfigure the PACKETPTR  for next packet on address event.MY troubles are:can we reconfigure the PACKETPTR  at any time or it is worked only when the start task is triggerd?For example,when the rado is receiving the current packet,I reconfigure the  PACKETPTR  register,does it effect the current packet receiving?

HI,

According to the documentation: "The CPU should reconfigure this pointer every time before the RADIO is started via the START task." The packet pointer is double buffered, so the value that is in the buffer when start is calld will be used by easyDMA. There is a more lengthy discussion here.
