https://devzone.nordicsemi.com/f/nordic-q-a/10508/ant-changing-a-bidirectional-channel-into-tx-onlyI am using the nRF51422 for sensor. This sensor is paired to a slave in the most simple way: the slave searches with a wildcard for a sensor and the stores the devicenumber. I do not use the pairingbit, because there is no trigger t put it on or off.en-USTelligent Community 13Mon, 30 Nov 2015 16:24:42 GMThttps://devzone.nordicsemi.com/thread/39070?ContentTypeID=1Mon, 30 Nov 2015 16:24:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:200f90cc-e72b-4e1e-82db-36a278656d06Petter Myhre<p>Section 12.1 in the S210 SoftDevice specification should give you an idea on the difference in current, you can find it <a href="https://www.nordicsemi.com/eng/Products/ANT/nRF51422#Downloads">here</a>. The x-axis has a strange unit, but you can replace 50 with 1 ms, 100 with 2 ms, 150 with 3 ms, and so on.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/39071?ContentTypeID=1Sat, 28 Nov 2015 12:34:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1c87949a-f5e5-40f1-9f07-2bdd869b50fdErik<p>OK, that is clear. Thanks for answering. I will try to measure the increase of the average power consumption. Is there a rule of thumb about this increase, when changing from TX only to bidirectional channel?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/39069?ContentTypeID=1Fri, 27 Nov 2015 12:38:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0dc8a285-e098-48a6-93ec-caa639c4ef77Petter Myhre<p>You need to close the channel, make the changes, and then reopen it. Or else you will get the NRF_ANT_ERROR_CHANNEL_IN_WRONG_STATE error.</p><div style="clear:both;"></div>
