https://devzone.nordicsemi.com/f/nordic-q-a/35443/channel-survey-with-s132v4-0-2Dear support team, Channel survey (RSSI report for each data channels) are now available on S132v6. However, for users who need to use v4.0.2, is there alternative method to achieve same functionality? 【Channel survey】 http://infocenter.nordicsemien-USTelligent Community 13Fri, 15 Jun 2018 09:31:03 GMThttps://devzone.nordicsemi.com/thread/136311?ContentTypeID=1Fri, 15 Jun 2018 09:31:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d065012-8399-4e55-8cf0-12b8cf4936f6Einar Thorsrud<p>Hi Jungo,</p> <p>I do not see a simple way of achieving this without SoftDevice support, as the information is hidden inside the SoftDevice and it protects the radio. The only option I can think about is to use the radio timeslot API to gain direct access to the radio peripheral, and then do the measure the RSSI for specific channels directly.</p> <p>Is the nRF a peripheral or central in this setup? If it is a peripheral, then some phones (at least iOS) will regularly check the RF environment and use channel map updates to avoid noisy channels without the nRF needing to do anything (other than use the new channel map, which is handled by the SoftDevice).</p><div style="clear:both;"></div>
