Gazell how to update channel table using num_channel_switches

HI, I look at nRF5 SDK doc about Gazell,see that 'the nrf_gzll_device_tx_info_t contains the num_channel_switches parameter which can be used by application to determine wheather the RF channels are reliable.'But I don't know how to achieve that,for example,when to update the channal table?Shoul change all the channals or only change the bad channal?

  • Hi

    It is not common to dynamically change the channel table in Gazell. The channel table is assumed to be fixed, but the channel you will use at any time can change.

    If you have a lot of channel switches it could also be caused by being at the limits of the range, so there is no guarantee that updating the channel table should work.

    The most important factor is to make sure the channels in the table are spread over the entire 2.4GHz ISM band (2400-2483.5MHz).

    Best regards
