Specifying channels to use in PAwR train

[Mohammad Afaneh]

I am using nRF Connect SDK v2.4.0 and an nRF5340 DK set up as a PAwR advertiser. Is it possible to specify the channels to use in the Periodic Advertising train? I found the API bt_le_set_chan_map(), but wondering if this is restricted to connections or if it can also be used for PAwR.

Hi, 

bt_le_set_chan_map() should work for:

• Connections as Central
• Extended Advertisers
• Periodic Advertisers
• PAwR Advertisers
• BIS sources. 

So you can use it for a PAwR Advertiser. It will take 10 Periodic Intervals (time from one Subevent #0 to the next Subevent #0) after the call to bt_le_set_chan_map() before the channel map update takes effect. This is to ensure all synchronized devices receive the updated channel map before switching.
