https://devzone.nordicsemi.com/f/nordic-q-a/26477/setting-ant-power-levelI&#39;m wondering which is the proper way to adjust the ANT power level? I&#39;ve seen some posts that seem to suggest that the proper way is by the use of the the BLE Gap call: err_code = sd_ble_gap_tx_power_set(TX_POWER_LEVEL); APP_ERROR_CHECK(err_codeen-USTelligent Community 13Fri, 03 Nov 2017 05:17:20 GMThttps://devzone.nordicsemi.com/thread/104195?ContentTypeID=1Fri, 03 Nov 2017 05:17:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ca4ff5e6-2285-421e-9f5f-3823a2187489Petter Myhre<p>I see, I&#39;m not aware of any requirements. I assume it should work independent of the channel being open or not.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104194?ContentTypeID=1Fri, 03 Nov 2017 02:11:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d482886d-f905-4cc3-9179-ba12a56f0331Tim Clark<p>It &#39;seems&#39; to be working, but it&#39;s why I was inquiring in the separate thread on RSSi, so that I could make sure :-) Could you also tell me if there are any requirements for calling the sd_ant_channel_radio_tx_power_set(...) - whether the channel should be open, or if it&#39;s ok to do so before open, and/or when it&#39;s closed? The documentation is, shall we say, a bit &#39;sparse&#39; in this area. Thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/104196?ContentTypeID=1Thu, 02 Nov 2017 22:00:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b6b04fdd-1398-483a-8ee2-1aafe1cc0f4aPetter Myhre<p>If you are using ANT you should use sd_ant_channel_radio_tx_power_set(). Do you have any trouble using this?</p><div style="clear:both;"></div>
